General Information
Communications
The Tracer LCI-I controller communicates via Trane Comm5 protocol. Typically, a communication
link is applied between unit controllers and a building automation system. Communication also is
possible via Rover service tool. Peer-to-peer communication across controllers is possible even
when a building automation system is not present.
You do not need to observe polarity for Comm5 communication links.
The controller provides four terminals (see figure 1) for the Comm5 communication link
connections, as follows:
•
Two terminals for communication to the board
•
Two terminals for communication from the board to the next unit (daisy chain)
The Comm5 communications protocol allows peer to peer communications between controllers,
which allows controllers to share information or data. A communicated variable input such as
setpoint, space temperature, or outdoor air temperature has priority over a locally wired input to
the controller.
For example: If the LCI-I controller has a wired outdoor air temperature sensor and Tracer Summit
or another Comm5 controller sends it a communicated outdoor air temperature, the
communicated value is used by the LCI-I controller. If a communicated input value is lost, the LCII controller reverts to using the locally wired sensor input.
Device addressing
Comm5 devices are given a unique address by the manufacturer. This address is called a Neuron
ID. Each LCI-I controller can be identified by its unique Neuron ID, which is printed on a label on
the controller (see figure 1.) The Neuron ID is also displayed when communication is established
using Tracer Summit or Rover service tool. The Neuron ID format is 00-01-64-1C-2B-00.
LonTalk communication link wiring requirements
The LonTalk communications link is for connection to a Building LonTalk Network.
The Communications link wiring is dependent on the network architecture. It is recommended that
a System Integrator refer to "LonWorks FTT-10A Free Topology Transceiver User's Guide" by the
Echelon Corporation for proper wire selection. The physical limits are defined in Chapter 4,
Network Cabling And Connection. This User's Guide is available on the Echelon Web page. A
typical wire recommendation is Belden 85102, single twisted pair, stranded 19/29, unshielded, 150
C.
Wire characteristics
UCM communication-link wiring must be low capacitance, 18-gauge, shielded, twisted pair with
stranded, tinned-copper conductors. For daisy chain configurations, limit the wire run length to
5,000 ft (1524 m). Truck and branch configurations are significantly shorter (see Figure 8). Comm5
wire length limitations can be extended through the use of a link repeater.
Wire capacitance (measured in picofarads/foot [pF/ft] or picofarads/meter [pF/m]) between
conductors must be 23+/-2 pF/ft (72+/-6 pF/m).
Link configuration and termination
Communication-link wiring must use one of the following configurations:
10
•
Daisy chain configuration (preferred), shown in Figure 3, p. 11
•
Trunk and branch configuration, shown in Figure 4, p. 12
RT-SVP06A-EN
General Information
Daisy chain configuration for communication-link wiring (preferred
configuration)
•
Limit total wire length to 5,000 ft (1,524 m). (Comm5 wire length limitations can be extended
through the use of a link repeater).
•
See the following section on Termination resistance placement for Comm5 links.
Trunk and branch configuration for communication link wiring
•
Total wire length for all branches is limited to 1,600 ft (500 m). (Comm5 wire length limitations
can be extended through the use of a link repeater.)
•
The maximum number of branches is ten.
Note: See the following section on termination resistance placement for Comm5 links.
Figure 3. Daisy chain configuration for communication-link wiring (preferred configuration)
RT-SVP06A-EN
11
General Information
Figure 4. Trunk and branch configuration for communication link wiring)
Termination resistance placement for Comm5 links
To correctly install a Comm5 link, termination resistors are required. For daisy chain configurations,
the termination resistance (measured in ohms) must be 100 ohms at each end. For trunk and branch
configurations, the termination resistance must be 50 ohms (use two termination resistors in
parallel).
For correct termination placement, follow the guidelines below:
12
•
Terminate the daisy chain configuration with a resistor at the extreme end of each wire.
•
Terminate a trunk and branch configuration with a resistor or resistors placed at one point on
the link. The termination resistance for trunk and branch configuration can be achieved by using
two terminating resistors in parallel. While it is not necessary that the termination resistance
be placed at the controller, it may be the most convenient.
•
When terminating a trunk and branch configuration, it is best to terminate at the point where
the branching occurs or at a point very close to it.
•
If the link contains more than one type of wire, the link will probably have to be manually tuned.
Trane recommends that only one type of wire be used for the Comm5 communication link.
•
A set of as-built drawings or a map of the communication wire layout should be made during
installation. Any sketch of the communication layout should feature the terminating resistor
placement.
RT-SVP06A-EN
General Information
Figure 5. Daisy chain resistor placement
Recommended wiring practices
The following guidelines should be followed while installing communication wire.
•
Comm5 is not polarity sensitive. Trane recommends that the installer keep polarity consistent
throughout the site.
•
Only strip away 2" maximum of the outer conductor of shielded cable.
•
Make sure that the 24VAC power supplies are consistent in how they are grounded. Avoid
sharing 24VAC between Comm5 UCMs.
•
Avoid over-tightening cable ties and other forms of cable wraps. A tight tie or wrap could
damage the wires inside the cable.
•
Do not run Comm5 cable alongside or in the same conduit as 24VAC power.
•
In an open plenum, avoid lighting ballasts, especially those using 277VAC.
•
Do not use a trunk and branch configuration, if possible. Trunk and branch configurations
shorten the distance cable can be run.
Network variable summary
The following section describes network variable support for both the DAC and SCC profiles, as
well as "open" variables (utilizing SNVT/SCPT) from Trane Extensions. The three columns on the
right indicate which variables are supported on which product(s). If a row is grayed out, the
corresponding variable is not implemented or not used by the controller at this time. Refer to the
Lonmark profiles for more details on standard network variables:

Network Variable Input Definitions
The network variable input definitions are listed alphabetically by the nviName. When an NVI is
invalid, the unit will decide proper operation based on its local inputs.
Application Mode Input, nviApplicMode
network input SNVT_hvac_mode nviApplicMode; SCC and DAC profile
Used to coordinate the controller with any supervisory controller. Default value will be adopted at
power-up and in case of not receiving an update within the specified receive heartbeat time. Refer
to Appendix Table 44, p. 95 for more details on how nviApplicMode is utilized. Default service type
= unacknowledged.
IntelliPak FAU products will only use HVAC_AUTO, HVAC_OFF, HVAC_FAN_ONLY and HVAC_NUL.
IntelliPak RT and CSC products will only use HVAC_AUTO, HVAC_HEAT, HVAC_MRNG_WRMUP,
HVAC_NIGHT_PURGE, HVAC_PRE_COOL, HVAC_COOL, HVAC_OFF, HVAC_FAN_ONLY and
HVAC_NUL. HVAC_NUL is treated the same as HVAC_AUTO. All other enumerations are defined
as HVAC_AUTO for IntelliPak products. For the HVAC_FAN_ONLY enumeration, heating and
cooling are locked out and will override nviAuxHeatEnable, nviComprEnable, nviPriCoolEnable,
and nviPriHeatEnable. HVAC_DEHUMIDIFICATION (14) is not supported in nviApplicMode by
IntelliPak products, as dehumidification is only activated by setpoints and space conditions. The
unit should be unoccupied before sending the HVAC_MRNG_WRMUP, HVAC_NIGHT_PURGE, or
HVAC_PRE_COOL.
For IntelliPak Rooftop or CSC products, when nviApplicMode = HVAC_MRNG_WRMUP,
HVAC_NIGHT_PURGE, or HVAC_PRE_COOL, refer to the table below for network variable

Note 1: The Morning Warmup function must be disabled at the human interface General Unit Functions Setup Submenu.
Note 2: The Morning Warmup function must be enabled at the human interface General Unit Functions Setup Submenu.
Note 3: If the unit was unoccupied or off before receiving HVAC_MRNG_WRMUP and the space temperature is below the morning warmup setpoint, the
unit will transition into it’s native morning warmup mode and report HVAC_MAX_HEAT, otherwise it will report HVAC_MRNG_WRMUP.
Note 4: Although the communicated occupancy indicates unoccupied mode, as expected, the unit is actually in occupied mode, which is displayed at the
human interface. This is required since the IntelliPak unit controller design only provides duct static pressure control and economizing to the
discharge air temperature setpoint in occupied modes.
Network Variable
Auxiliary Heat Enable Input, nviAuxHeatEnable

First of two inputs used by a slave unit to allow control by a master unit in a multi-unit cluster.
Before a unit will become a slave, nviMasterSlave1 and nviMasterSlave2 must be bound and
nvoMasterSlave1 and nvoMasterSlave2 must be unbound. Once a unit is a slave, all control data
comes from the master unit and all other NVIs are ignored. All NVOs are still processed as usual.
Default value will be adopted at power-up and in case of not receiving an update within the
specified receive heartbeat time. Default service type = unacknowledged.
Clustering is currently supported only in IntelliPak Rooftop products.

Minimum Outdoor Air Flow Setpoint Input, nviMinOAFlowSP
network input SNVT_flow nviMinOAFlowSP;
DAC profile
Used to set the minimum outdoor air flow rate setpoint from the network. When a valid value is
present, this input has priority over any local minimum outdoor air flow setpoint. Invalid value will
be adopted at power-up, until an update is received. Does not use the receive heartbeat function.
Default service type = unacknowledged.
Range, 0 to 28,317 liters/sec
Invalid Value, 0xFFFF = 65,535 liters/sec
Outdoor Air Minimum Position Input, nviOAMinPos
network input SNVT_lev_percent nviOAMinPos;
SCC and DAC profile (see nviTraneVar1)
Used to set the minimum outdoor air damper position. When a valid value is present, this input
has priority over any local minimum outdoor air damper position setpoint. Invalid value will be
adopted at power-up, until an update is received. Does not use the receive heartbeat function.
Default service type = unacknowledged.
For IntelliPak FAU products without a return air damper, minimum position requests below 25% are
ignored. nviOAMinPos is overridden when nviApplicMode or nviHeatCool (SCC) is set to
HVAC_MRNG_WRMUP, HVAC_NIGHT_PURGE, or HVAC_PRE_COOL. nviOAMinPos can be
overridden by Trane proprietary profile extension variables.

Occupancy Override Input, nviOccManCmd
network input SNVT_occupancy nviOccManCmd;
SCC and DAC profile
Used to manually command the controller into different occupancy modes. This input is used in
conjunction with nviOccSchedule and nviOccSensor (if installed) to determine the effective
occupancy mode. nviOccSchedule appears in both SCC and DAC profiles, nviOccSensor in SCC
profile only. Default value will be adopted at power-up. Does not use the receive heartbeat
function. Should not be bound to a send heartbeat nvo. Refer to Table 24, p. 84, Effect of
Occupancy Commands on the Controller for more details on how nviOccManCmd is utilized.
Default service type = unacknowledged.
For IntelliPak products, there is no time-out for nviOccManCmd, it is not heartbeated, and the value
is not preserved when power is lost (it is always initialized to OCC_NUL on power-up.)
nviOccManCmd enumerations of OC_UNOCCUPIED and OC_STANDBY can be bypassed. Pressing
the zone sensor module Timed Override On button (if installed) can change the effective occupancy
from unoccupied to standby or bypass. The bypass timer is set to the value in nciBypassTime
whenever nviOccManCmd equals OC_BYPASS or the local zone sensor Timed Override On request
is received. After the bypass timer is set to nciBypassTime, the controller begins counting down
to zero. The bypass timer is cleared to zero whenever nviOccManCmd does not equal OC_BYPASS
or the local zone sensor with Timed Override Cancel request is received. If nciBypassTime is set
to zero, it disables the OC_BYPASS enumeration for nviOccManCmd and nviOccSchedule. The
human interface displays "Occupied TOV" when placed in bypass by a local zone senor with Timed
Override On button and "Occupied" when placed in bypass by nviOccManCmd, nviOccSchedule,
or nviOccSensor.
For IntelliPak products, the values 4 through 254 are manufacturer-defined to be OC_NUL.

Node Object Behavior
normal
The Request does not change the state of the object. The Status of the object is sent via nvoStatus. See nciApplication for
a description of how to determine the unit type and which profile is supported.
update status
Status of the node object is sent via nvoStatus. The status bits of the node object (with the exception of invalid_request and
invalid_id) are defined to be the inclusive OR of the status bits of all the other objects in the node, SCC and DAC in this case.
report mask
Send a mask of supported status bits via nvoStatus. A one bit in the mask means that the node may set the corresponding
bit in nvoStatus when the condition defined for that bit occurs. A zero means that the bit will never be set by the node.
clear status
No status bits cleared. Status of the object is sent via nvoStatus.
clear alarm
Clears most latching diagnostics. Re-sends automatically resetting diagnostics if no latching diagnostics are present.

(see SCCX and DACX
A structure used to report the current Enable/Disable status of the discharge air controller
economizer. A space temp controller uses nvoTraneVar7. See the spec for a complete description
of when the economizer is enabled and disabled.
nvoEconEnabled is the enable/disable status of the economizer. It is defined in the profile as
"binary". If the economizer is enabled, it reports (1, 200). If the economizer is disabled, it reports (0,

IntelliPak products can have both an air-side economizer and a water-side economizer. Either or
both can be enabled or disabled independent of the other. If only the air-side or only the water-side
economizer is installed then the status of that economizer is reported. If both air-side and waterside economizers are installed, the status of the water-side economizer is reported. IntelliPak

Effective Occupancy Output, nvoEffectOccup
network output SNVT_occupancy nvoEffectOccup;
SCC and DAC profile
Used to indicate the current occupancy of the controller. This information is typically reported to
a supervisory controller, or provided to another controller to coordinate the operation of multiple
units. The occupancy mode is determined by a combination of optional input network variables
and logic in the controller, as defined by the controller manufacturer. Network variables which can
impact the occupancy state of the controller are nviOccManCmd (SCC/DAC), nviOccSchedule (SCC/
DAC), and nviOccSensor (SCC only). The unit is always in one of the four possible occupancy
states. Refer to Table 24, p. 84, Effect of Occupancy Commands on the Controller for more details
on how nvoEffectOccup is utilized.
For IntelliPak products, there is no time-out for nviOccManCmd, it is not heartbeated, and the value
is not preserved when power is lost (it is always initialized to OCC_NUL on power-up.)
nviOccManCmd enumerations of OC_UNOCCUPIED and OC_STANDBY can be bypassed. Pressing
the zone sensor module Timed Override On button (if installed) for less than 8 seconds can change
the effective occupancy from unoccupied or standby to bypass. The bypass timer is set to the value
in nciBypassTime whenever nviOccManCmd equals OC_BYPASS or the local zone sensor Timed
Override On request is received. After the bypass timer is set to nciBypassTime, the controller
begins counting down to zero. The bypass timer is cleared to zero whenever nviOccManCmd does
not equal OC_BYPASS or the local zone sensor with Timed Override Cancel request is received. If
nciBypassTime is set to zero, it disables the OC_BYPASS enumeration for nviOccManCmd and
nviOccSchedule. If nciBypassTime is set to zero, it does not disable the TOV Request or TOV Cancel
Request in nvoTraneVar7. The human interface displays "Occupied TOV" when placed in bypass
by a local zone senor with Timed Override On button and "Occupied" when placed in bypass by
nviOccManCmd, nviOccSchedule, or nviOccSensor. Pressing the zone sensor module Timed
Override On button for more than 8 seconds will cause the LCI-I controller to broadcast a Service
Pin Message (Neuron ID and Program ID.)

Local Space Temperature Output, nvoLocalSpaceTmp
network output SNVT_temp_p nvoLocalSpaceTmp;SCC profile
Value of hardwired input. Can be used for averaging or monitoring.
When a large area is to be controlled with multiple units the effective space temperature should
be shared by all units to prevent unequal loading / fighting. This requires a method to average the
temperatures near each unit. This variable also can provide a means to monitor local conditions
if a communicated space temperature is being used. This is not intended as a way of using the
hardwired input as a general purpose input when nviSpaceTemp is present.
For IntelliPak products, when nviSpaceTemp is invalid, nvoLocalSpaceTmp will equal one of the
following values, in this order, based on sensor source assignments at the human interface:
1. Monitor Temperature Source
2. Morning Warm Up Temperature Source during Morning Warm Up
3. Unoccupied Zone Temperature Source during unoccupied mode

Note: Highlighted fields are NOT supported by the controller, they will always be 0 in nvoStatus.
invalid_id
A status of invalid_id is reported whenever an nviRequest is received for an object id
that is not implemented in the node. Invalid_id is mandatory and is always present and
is not set in the report mask.
invalid_request
A status of invalid_request is reported whenever an nviRequest is received for an nonimplemented function. Invalid_request is mandatory and is always present and is not
set in the report mask.
disabled
A status of disabled is reported if a valid object request code is received for the
disabled object. The node object is never disabled. The SCC object is disabled when
the LCI unit type is FAU, CSC DAC, or RT DAC. The DAC object is disabled when the LCI
unit type is CSC SCC or RT SCC. See nciApplication for details on how the LCI unit type
and supported profile is determined.
The disabled and the out_of_service bits are always both set at the same time in the
IntelliPak unit.
out_of_service
A status of out_of_service is reported if a valid object request code is received for the
out_of_service object. The node object is never out_of_service. The SCC object is
out_of_service when the LCI unit type is FAU, CSC DAC, or RT DAC. The DAC object is
out_of_service when the LCI unit type is CSC SCC or RT SCC. See nciApplication for
details on how the LCI unit type and supported profile is determined.
locked_out
A status of locked out is reported if a valid object request code is received for the
locked out object. The node object is never locked out. The DAC and SCC objects are
66
RT-SVP06A-EN
Network Variable Output Definitions
locked out when one or more circuits are locked out due to 1) Demand Limit, 2) Frost
Protection, 3) Low Ambient, or 4) Low Condenser Water temp (CSC water-cooled
condenser or Rooftop evaporative condenser only). See nciApplication for details on
how the LCI unit type and supported profile is determined.
manual_control
A value of TRUE is reported if the controller is under local control. Tracer Summit will
use this bit to indicate whether the IntelliPak unit is in local or remote control.
in_alarm
A value of TRUE is reported if the controller has a diagnostic condition. See
nvoAlarmMessage for the list of IntelliPak diagnostics that set this bit and
nvoUnitStatus in_alarm bit.
report_mask
Report_mask status is used to document the optional status bits that are supported by
the object. The obj_request code RQ_REPORT_MASK causes the object to respond
with a mask of supported optional status bits via nvoStatus. A ONE in the mask means
that the object may set the corresponding optional bit in the object status when the
condition defined for that optional bit occurs. A ZERO means that the optional bit will
never be set by the object. When reporting status in response to a RQ_REPORT_MASK,
the report_mask bit will be set to distinguish this from other forms of status. The
invalid_id and invalid_request bits are mandatory and are not set in the report_mask
status.
When Transmitted
nvoStatus is transmitted whenever a request is received on the nviRequest input and
as one of the heartbeat nvo's. The node object status is sent during the first heartbeat
nvoStatus transmission. Then either the SCC object status or the DAC object status is
sent during the second heartbeat nvoStatus transmission, depending on which profile
is being used. And then the cycle repeats.
Update Rule
The application must update the status such that a poll of the status following the
request returns a reasonable value.

Unit Status Output, nvoUnitStatus
network output SNVT_hvac_status nvoUnitStatus;
SCC and DAC profile
A structure used to report controller status.
For IntelliPak CSC and RT products, the electric heat capacity reported in the
"heat_output_primary" field is divided equally between the number of stages available.
This may or may not reflect the actual capacity step for a given stage. This was done
because of the number of variations in capacity steps due to model number variations,
line voltage, wiring, and sizes of heater elements.
Unlike nvoEconEnabled, nvoUnitStatus.econ_output shows percent open.
nvoEconEnabled is the enable/disable status of the economizer and is defined in the
profile as "binary" (does not show percent.) If the economizer is enabled, it reports (1,
200). If the economizer is disabled, it reports (0, 0). If there is no economizer, it reports

This configuration property is not used by the controller for any purpose. It is used to identify the
type of HVAC unit that is being controlled. Although the HVAC Unit Type can be read via the
network, it typically should not be changed. The configuration property SCPThvacType should be
declared using the device_specific_flg so that it can be protected by the network configuration tool
to avoid inadvertent modification in the field by the installer. The use of the device_specific_flg will
also allow devices to have a common *.XIF file where the only network interface difference is the
value of this configuration property. If it is changed, the user must verify the application for the
selected HVAC Unit Type.

Sequence of Operation
Sequence of Operation
The Tracer LCI-I is a configurable controller. All of the controller's sequences of operation are
predefined with no need for programming the controller. Configurable parameters are provided to
allow user adjustments to the controller's operation. For example, the minimum occupied outdoor
air damper position can be changed.
All configuration parameters are set to defaults predetermined through extensive unit testing in
several different operating conditions. The factory default settings are also based on the unit
configuration and ordering information.
The Tracer LCI-I controller is configurable to operate in one of three air handling modes of
operation:
•
constant volume (CV) space temperature control
•
constant volume (CV) discharge air temperature control
•
variable air volume (VAV) discharge air temperature control
For constant volume space temperature control operation (also called cascade control), the Tracer
LCI-I controller requires both a space temperature and discharge air temperature sensor. In this
control mode, the controller compares the space temperature to the space heat/cool setpoint to
generate a discharge air temperature setpoint. The controller modulates its heating or cooling
outputs to control the discharge air temperature to the discharge air temperature setpoint. This
calculated discharge air temperature setpoint is the desired discharge air temperature (supply air
temperature) that the unit must deliver to maintain space temperature at the space heating or
cooling setpoint.
The space temperature can be hardwired to RTM module's Zone Temp input (10k OHM thermistor
only) or can be communicated to the controller via Comm5. Similarly, cooling and/or heating
setpoint(s) can be provided via a hardwired zone sensor, a night setback panel, a Comm5
communicated value, or by using the stored default setpoints in the controller.
The discharge air temperature must be a hardwired analog input to the RTM module (10k OHM
thermistor only).
The Tracer LCI-I controller can be configured to operate in a constant volume discharge air
temperature control mode. The controller only requires a discharge air sensor (10k OHM thermistor
only) to operate in this mode. Constant volume discharge air temperature control modulates the
heating or cooling outputs to maintain the discharge air temperature at the discharge air
temperature setpoint.
When the Tracer LCI-I controller is configured for variable air volume (VAV) discharge air
temperature control, the controller maintains a discharge air temperature according to the cool/
heat discharge air setpoint, and duct static pressure at the duct static pressure setpoint. The
controller maintains duct static pressure by modulating the supply fan's inlet guide vanes (IGV) or
the variable frequency drive (VFD).
The duct static pressure input can either be hardwired or communicated to the controller via
Comm5. If both a communicated value and a hardwired duct static pressure value exists, the
communicated value has precedence. Similarly, the duct static pressure setpoint can either be
configured (default) or communicated. If a communicated value is present, the communicated
value has precedence.
If a space temperature input is provided to the controller when configured as constant volume
discharge air control or variable air volume control, the controller can be configured to use the
space temperature to perform morning warmup and daytime warmup functions. Morning or
daytime warmup functions allow the controller to automatically change to heating if space
temperature is less than the heating setpoint. Morning or daytime warmup functions cannot be
initiated through a communicated request.
Other temperature inputs, such as mixed air temperature or outdoor air temperature, aid the
controller's ability to maintain comfort and protect the unit.
RT-SVP06A-EN
81
Sequence of Operation
Active heating and cooling setpoints are affected by the controller's occupancy mode. Valid
occupancy modes for the three different control modes are shown below.
Table 23. Tracer LCI-I occupancy modes of operation
Constant volume space temperature control
• Occupied (default)
• Unoccupied
• Occupied standby
• Occupied bypass
Constant volume discharge air temperature control
• Occupied (default)
• Unoccupied
• Occupied bypass
Variable air volume discharge air temperature control
• Occupied (default)
• Unoccupied
• Occupied bypass
The controller occupancy mode is determined by either a zone sensor, night setback panel,
changeover switch or via a communicated request (from a system-level controller or another peer
controller).
Power up sequence
When 24VAC power is initially applied to the Tracer LCI-I controller and UCM, the following
sequence occurs:
•
Red Service LED and green Status LED blink intermittently.
•
Internal unit communications begins (IPC TXA and RXA LEDs blink)
•
Green Status LED turns on solid.
•
Unit will remain in local (standalone) control until Comm5 control data is received. Note: The
unit must also be changed from LOCAL to BAS/NETWORK (remote) control in the Human
Interface (HI) Setup menu.
•
Power-up control wait feature is applied.The controller waits 300 seconds to allow ample time
for the communicated control data to arrive. If after 300 seconds, the controller has not received
any communicated control data, the unit assumes local (standalone) operation.
•
Normal operation begins.
Service test cannot be initiated until the power up sequence has completed. Refer to the Service
Test section of the Programming and Troubleshooting Guide.
Occupied and Unoccupied Operation
The valid occupancy modes of the Tracer LCI-I controller are:
82
RT-SVP06A-EN
Sequence of Operation
Occupied
Normal operating mode for occupied spaces or daytime operation.
Unoccupied
Normal operating mode for unoccupied spaces or nighttime operation.
Occupied Standby
Constant volume mode used to reduce the heating and cooling demands during the occupied
hours when the space is vacant or unoccupied. For example, the controller may use occupied
standby mode for a classroom while the students are out of the room.
Occupied Bypass
Mode used for timed override conditions. For example, if the controller is in unoccupied mode and
someone presses the On button on the zone sensor or night setback panel, the controller is placed
in occupied bypass mode for 120 minutes (adjustable) or until someone presses the Cancel button
on the zone sensor.
The occupancy mode can be hardwired to the controller via the occupancy binary input or
communicated to the controller.
Determining the occupancy mode
The occupancy of the controller is determined by evaluating the combination of three potential
communicating inputs, as well as the hardwired occupancy input and the occupied bypass timer.
Three different communicating inputs affect the controller occupancy mode:
•
Occupancy—manual command
•
Occupancy—schedule
•
Occupancy—sensor
These inputs provide maximum flexibility, but the number of inputs you decide to use varies with
the application and the features available in your building automation system.
Occupancy—manual command. Some communicating devices may request occupancy
based on the information communicated in the network variable nvoOccManCmd. Trane systems
and zone sensors do not communicate this information to the controller, but the Tracer LCI-I
controller accepts this network variable as communicated input nviOccManCmd.
Occupancy—schedule. Building automation systems normally communicate an occupancy
request using the occupancy—schedule input. The Tracer LCI-I controller accepts communicated
occupancy schedule as a network variable input nviOccSchedule.
Occupancy—sensor. Some occupancy sensors may be equipped with the ability to
communicate an occupancy mode to the controller. In such devices, network variable input
nviOccSensor is used to communicate occupancy to the controller. Trane systems and zone
sensors do not currently send this variable. The hardwired occupancy input of this controller is
handled as if it is a communicated occupancy sensor input. When both a hardwired input and a
communicated input exist, the communicated input is used.

Notes:
1. The bypass timer is set to the value in nciBypassTime every time one of the following occurs:
1) receive nviOccManCmd = bypass
2) receive timed override ON request from the local zone sensor module
After the bypass timer is set to nciBypassTime, it counts down to zero.
The bypass timer is cleared to zero every time one of the following occurs:
1) receive nviOccManCmd = (occupied or unoccupied or standby or undefined)
2) receive timed override CANCEL request from the local zone sensor module
To disable the network bypass timer, set nciBypassTime to zero. This disables the nviOccManCmd and nviOccSchedule OC_BYPASS enumeration.
This does not disable the local bypass timer, used by the zone sensor with timed override button, which is hard-coded to be three hours. However, if
nciBypassTime is set to zero and either nviOccManCmd or nviOccSchedule are set to OC_BYPASS, the local zone sensor timed override button is
disabled.
2. nviOccSensor is SCC only. The DAC profile uses the NUL rows in this column.
Emergency override modes
The Tracer LCI-I controller can be placed into emergency override via the communication link.
Emergency override allows a building automation system such as Trane Tracer Summit to
pressurize, depressurize, or purge the air from a building space. It can also be used to shut down
the controller's operation of the unit.
The emergency override command influences the controller's supply fan, inlet guide vanes,
exhaust fan, exhaust dampers, outdoor air damper, heat, Occ/Unocc relay, ventilation override
relay, and outdoor air preheater state to create the desired condition, as shown in the table below.

Configuration
Configurable parameters
The Tracer LCI-I controller is factory configured and commissioned with fixed sequences of
operation. All of the controller's configuration parameters are predefined and loaded based upon
the unit configuration. Some "as-built" configuration parameters are adjustable only at the human
interface. Tracer Summit or the Trane Rover service tool provides access to these parameters to
make adjustments to the controller's operation.
The Tracer LCI-I contains configuration parameters for the unit type to select the type of control
mode, cooling source, heating source, and outdoor air damper. Refer to Table 26. The control mode
selects the desired unit operation: constant volume space temperature control, constant volume
discharge air temperature control, or variable air volume control.

Application Information
Location Identifier
The Tracer LCI-I includes unit configuration for a location identifier. The maximum length of the
location identifier is 30 characters. You can modify this identifier and easily identify the unit based
on its physical location.
Standalone
Occupied/unoccupied
You can utilize the RTM module's occupancy input to switch between occupied and unoccupied
modes of operation. The standalone controller switches to occupied mode when the input is open.
Timed override
The range for the timed override bypass time is 0 to 240 minutes (configurable, nciBypassTime).
The default value for the bypass time is 120 minutes for SCC units and 0 minutes for DAC units.
The controller's space temperature analog input generates timed override On and Cancel requests
in the following manner. The controller interprets a momentary short of the space temperature
analog input as a timed override On request. The controller always accepts this timed override On
request and resets the bypass time. The controller only changes to occupied bypass if the controller
is in either the unoccupied or occupied standby mode. The controller stays in the occupied bypass
mode for the occupied bypass time or until someone presses the zone sensor's Cancel button.
The controller interprets a momentary fixed resistance of 1.5K OHM on the space temperature
analog input as a timed override Cancel request. The controller always accepts the Cancel request
and sets the bypass time to zero. The controller only acts on a Cancel request during occupied
bypass.
Morning warmup and daytime warmup
If the Tracer LCI-I controller is configured for constant volume discharge air temperature control or
variable air volume control, a space temperature sensor can be wired to the controller to provide
the morning warmup and daytime warmup sequence of operation. The space temperature and
setpoint inputs are used by the controller to determine if heating or cooling air should be supplied
to the space.
In heating, the controller creates a supply air temperature according to the configured discharge
air heating setpoint or communicated discharge air heating setpoint input. In cooling, the controller
maintains a supply air temperature according to the configured discharge air cooling setpoint or
communicated discharge air cooling setpoint input. If a valid communicated discharge air setpoint
exists, the controller uses the communicated value.
Configuration
Use the human interface to modify any of the controller's configuration parameters. Refer to the
current Programming and Troubleshooting Guide for more information.
Setpoint operation
Standalone unit controllers can use several different setpoint sources; the local zone sensor or
night setback panel input, Generic Building Automation System (GBAS) module, or the default (HI
keypad) setpoints (nciSetpoints).
Standalone peer-to-peer
Tracer LCI-I controllers allow peer-to-peer (also referred to as master/slave) data communication.
Data such as space temperature, setpoint, and occupancy can be shared from a master control to
a peer control with or without the presence of Tracer Summit.

RT-SVP06A-EN
Application Information
Table 37. Emergency override commands
Master
Controller
Zone
Sensor
Comm5 Link
Controller
Slave
Controller
Slave
Occupied/unoccupied
The standalone controller uses the binary input to switch between occupied and unoccupied.
The master controller (the unit controller with the hardwired occupancy input) in peer-to-peer
communication can send its occupancy mode to one or more slave controllers (so they all track
each other's occupancy mode). For these applications, you must use Rover service tool to set up
the controller. Refer to the Rover service tool product literature for more information.
Timed override
Peer-to-peer timed override requires at least two controllers. The first controller, commonly
referred to as the master, passes occupancy information to other controllers, commonly referred
to as slaves.
The master controller's zone sensor generates timed override On and Cancel requests in the
following manner. The master controller interprets a momentary short (greater than 3 seconds) on
the space temperature input as a timed override On request. During unoccupied mode, the On
request places the master controller in occupied bypass mode until the three hour (not
configurable) occupied timer expires or until someone presses the zone sensor Cancel button.
When the master controller's occupancy mode is communicated to one or more slave controllers,
the slave controllers echo the master's occupancy mode, including both On and Cancel requests.
The controller interprets a momentary fixed resistance (greater than 3 seconds) of 1.5K OHM by the
space temperature input as a timed override Cancel request. During occupied bypass mode, the
controller uses a Cancel request to return the controller to unoccupied mode.
Setpoint operation
Controllers sharing information peer-to-peer, also referred to as master/slave, can share a variety
of data, including the heating/cooling setpoint (communicated from a master to a slave).
Each controller derives its effective setpoint and default setpoints (including deadbands between
setpoints) from the setpoint input (hardwired or communicated). To make sure the peer-to-peer
setpoint application results in identical setpoints for each communicating controller, each
controller must have exactly the same default setpoints.
The standalone master controller derives its setpoint from either the local hardwired setpoint input
(if present) or from its default setpoints. Peer-to-peer applications often require the use of one
hardwired setpoint to be shared across two or more controllers. You can achieve this by wiring the
adjustable setpoint (typically included as a part of the Trane zone sensor module) to one controllerdefined as the master. Next, use Rover to set up the master and one or more slaves to share that
setpoint. For this application, each communicating controller uses the same setpoint.

Service push button
The Service push button (also known as Service Pin) is located on the left center board edge of the
Tracer LCI-I controller. It can be used to install the controller in a communication network. Pressing
the service push button will cause the LCI-I controller to broadcast it's Neuron ID and Program ID.
Refer to the Rover service tool product literature for more information.
Note:
1. If the Service push button is held down for more than 15 seconds, the controller will un-install from the communication
network (unconfigured state) and will no longer control the unit. This mode is indicated by the red Service LED flashing
once every second. Refer to the previous section on Red Service LED for more information. Use the Rover service tool or
another network management tool to restore the unit to normal operation. Refer to the Rover product literature for more

Troubleshooting
Diagnostics
Three different types of diagnostics are generated by the Tracer LCI-I controller to help you
troubleshoot abnormal unit operation.
Table 43. Diagnostic types
Alarm
The controller shuts down the unit to protect the unit and avert possible damage, or the controller cannot
operate until the diagnostic condition is corrected.
Service required
The controller disables certain sequences of operation only and attempts to maintain unit operation. For
example, if the outdoor air temperature sensor fails or is not wired, the Tracer LCI-I controller disables
(does not allow) economizer operation.
Informational
This type of diagnostic does not affect controller operation.
Notes:
1. When a local temperature/pressure sensor or setpoint has failed after being valid, the controller generates a diagnostic to
indicate the sensor or setpoint loss condition. The controller automatically clears the diagnostic once a valid sensor or
setpoint value is present (non-latching diagnostic).
2. If the local outdoor air temperature sensor fails and a communicated value is not present, the outdoor air damper is
opened to minimum position and economizer operation is disabled.
3. A space temperature failure diagnostic disables morning and daytime warmup sequence of operation when the controller
is configured for constant volume discharge air control or variable air volume control.
4. Some diagnostic messages can be configured as a service required or critical alarm using Tracer Summit or Rover service
tool.
5. See nvoAlarmMessage for a list of diagnostic messages.
Translating multiple diagnostics
The controller senses and records each diagnostic independently of other diagnostics. It is possible
to have multiple diagnostics present simultaneously. The diagnostics are reported in the order they
occur. Non-latching diagnostics automatically reset when the input is present and valid.
Resetting diagnostics
A reset clears any latching diagnostics and allows the controller to try to run the unit normally. If
the latching condition is still present, the controller immediately shuts down the unit. A reset will
reset a unit that is running normally. A reset is similar to cycling power to the unit. Unit diagnostics
can be reset from the local or remote human interface, by cycling power to the unit, or by sending
a request through the LCI-I controller.
There are many ways to reset unit diagnostics:
1. Local human interface
2. Remote human interface
3. Cycling power to the controller
4. Sending a reset request through the LCI-I controller via nviRequest enumeration 10 to the
correct DAC/SCC object or node.
Cycling power
When the controller's 24VAC power is turned off, then on, the unit cycles through a power up
sequence. By default, the controller attempts to reset all diagnostics at power up. Diagnostics
present at power up and those that occur after power up are handled according to the defined unit
diagnostics sequences (see the previous Diagnostics table).

Notes:
1. See the section titled "Local Fan Mode Arbitration" for more information on determining local fan mode arbitration.
2. Per the SCC profile, nviApplicMode overrides nviHeatCool, unless nviApplicMode is HVAC_AUTO, HVAC_TEST, or HVAC_NUL (for IntelliPak units, HVAC_TEST and HVAC_NUL are treated
as HVAC_AUTO.) If nviApplicMode is HVAC_AUTO, then nviHeatCool determines the effective mode of the unit.
3. nviApplicMode (and/or nviHeatCool) with an unsupported enumeration (other than 0, 6 or 9 for FAU and other than 0, 1, 3, 6 or 9 for RT/CSC) is treated as HVAC_AUTO.
4. See nviAuxHeatEnable (SCC), nviComprEnable (SCC), nviPriCoolEnable (DAC) and nviPriHeatEnable (DAC) for more information on cooling and heating lockout arbitration.

Notes:
1. NSB Occ Zone Cooling Setpoint and NSB Occ Zone Heating Setpoint are not communicated internally by the RTM.
Therefore, for these two cases, we must fall back to using Default Occ Zone Cooling Setpoint and Default Occ Zone
Heating Setpoint, respectively.
2. At the time of this writing, the GBAS 0-10V module is not available.
3. When a local temperature/pressure sensor or setpoint has failed after being valid, the controller generates a diagnostic to
indicate the sensor or setpoint loss condition. The controller automatically clears the diagnostic once a valid sensor or
setpoint value is present (non-latching diagnostic).
4. If the local outdoor air temperature sensor fails and a communicated value is not present, the outdoor air damper is
opened to minimum position and economizer operation is disabled.
5. A space temperature failure diagnostic disables morning and daytime warm-up sequence of operation when the controller
is configured for constant volume discharge air control or variable air volume control.
6. Some diagnostic messages can be configured as a service required or critical alarm using Tracer Summit or Rover service
tool.
7. See nvoAlarmMessage for a list of diagnostic messages.
