Components and Options
Residential applications include: Condominiums, apartments, student residences/dormitories,
assisted living/retirement facilities, and military barracks.
Trane recommends the remote mounting of low voltage (24V) thermostats to achieve optimal zone
control. When thermostats are remote mounted, a terminal strip is provided inside the unit for field
connection to the remote thermostat. Unit mounting of thermostat is also available, however all
thermostats are shipped loose for field installation after the unit is installed, drywall is applied and
the walls are painted.
The standard standalone thermostats listed above cycle a two position (on/off) valve and feature
discrete speed fan speed operation. If modulating (0-10V DC or 3-wire floating point) valve
actuators or modulating or 0-10V DC EC motors are a requirement, a thermostat or controller with
the necessary analog outputs must be used.
Tracer ZN521 Zone Controller
The Tracer ZN521 is a factory-installed LonTalk® control board designed to provide control of the
fan-coil products (see Figure 9).
The Tracer ZN521 controller is designed to be used in the following applications:
• As part of the Trane Tracer Summit building automation system, the Tracer ZN521 becomes an
important part of the Trane Integrated Comfort system (ICS).
• The Tracer ZN521 can function as a completely standalone controller in situations where a
building automation system (BAS) is not present.
• For situations when a non-Trane BAS is present, the Tracer ZN521 can be where ever a LonTalk
front-end system is present.
Through building management of the HVAC system, optimizing energy consumption becomes
possible at a zone level. Each unit is capable of functioning independently of one another during
occupied and unoccupied hours of the day. This allows the temperature setpoint and ventilation
setting to be changed automatically based on zone usage (see Figure 10).
Figure 9. Tracer ZN521 controller
Features include:
• Automatic fan-speed reset
• Automatic ventilation reset
• Manual output test
• Filter maintenance
• Master slave
• Water valve override
• Freeze avoidance
• Interoperability
• Three generic I/O ports

Components and Options
Two Systems in One
In an ICS environment, the Tracer ZN521 is pre-designed to install quickly and easily into the
system. Since the controller is mounted on the unit, the start-up time for the entire system is
minimized. Trane becomes the single source of responsibility for the equipment, unit controls, and
building automation system.
Once power is applied to the controller, it will automatically start up and run based upon the
setpoint on the local zone sensor. The Tracer ZN521 is certified to the interoperable L
ON
M
ARK
®
Space Comfort Controller profile. This allows the controller to be used with another vendor’s BAS
and thereby still provide the high quality of factory installation. In addition, the Tracer ZN521
provides one of the most extensive interoperable data lists of any controller of its type in the
industry.
Automatic Fan and Ventilation Reset
With the Tracer ZN521 controller, a multi-speed fan control for the fan coil delivers the airflow
output customized to support the cfm space needs. When less cfm is necessary to meet the load
of the zone (typically 75 to 80 percent of the time), the equipment operates on low speed. However,
if the room temperature rises, the controller will switch to high speed.
Manual Output Test
The Tracer ZN521 controller includes a manual output test function. This function may be initiated
from the blue test push button on the controller or through the Rover™ service tool. This feature
is used to manually exercise the outputs in a defined sequence.
The purpose of this test sequence is to verify output and end device operation. The manual output
test function may also be used in the following situations:
• Reset latching diagnostics
• Verify output wiring and operation
• Force the water valve(s) open to balance the hydronic system during installation set-up or
service.

Components and Options
Filter Maintenance
Filter status for the controller is based on the cumulative run hours of the unit fan. The controller
compares the amount of fan run time against an adjustable fan run hour (stored in the controller)
to determine when maintenance is recommended for the unit. The run-hours value may be user
edited as required (through Rover). The valid range for the fan run hours limit is 0 to 5000 hours
with a default of 600 hours. Once the run hours limit has been exceeded, the controller generates
a maintenance required diagnostic (unit will not shut-down). The user will be notified of this
diagnostic through the building automation system or when a Trane Service Tool is communicating
with the controller.
Master Slave (Data Sharing)
Because the Tracer ZN521 controller utilizes L
ON
W
ORKS
® technology, the controller can send or
receive data (setpoint, heat/cool mode, fan request, space temperature, etc.) to and from other
controllers on the communication link with or without the existence of a building automation
system. This applies to applications where multiple units might share one zone sensor for both
stand-alone (with communication wiring between units) and a building automation system.
Water Valve Override
The Tracer ZN521 can be commanded via the Rover service tool to open all hydronic valves
100 percent. This allows for the faster water balancing of each unit and the entire system when the
command is sent globally to all controllers. A properly balanced system is essential for proper and
efficient operation.
Hydronic Coil Freeze Protection (Freeze Avoidance)
Fan coil systems in cold climates need to take precautions to avoid hydronic coil freeze-up. The
Tracer ZN521 does this from three different aspects. Any of these methods of protections will result
in the unit fan being disabled, the outside air damper being shut, and the hydronic valves being
opened 100 percent.
The three methods of freeze avoidance include:
1. A binary freeze protection thermostat is mounted on the coil and will cause a latching diagnostic
if the coil temperature falls below 35°F.
2. An analog discharge air sensor monitors the temperature of the air coming off of the coil and
if the temperature falls below 40°F the outside air damper is closed, the fan is turned off and
the valves are fully opened.
3. When in the unoccupied mode the Tracer ZN521 has an adjustable freeze avoidance setpoint.
If the outside air temperature is below the setpoint the unit will open the valves to allow water
to flow through the coils.
Interoperability
Interoperability allows the owner freedom to select multiple vendors, and multiple products. With
this advantage, the owner can choose the best products, the best application, and the best service
from a variety of suppliers to meet their evolving building control needs in a cost effective manner.
Generic Binary Input/Output
The three generic binary inputs/outputs are not part of the normal control, but are actually
controlled through the Tracer Summit system (when present) to issue commands to the Tracer
ZN521 control to turn the generic inputs/outputs of add-on equipment (such as baseboard heating,
exhaust fans, occupancy sensor, lighting, etc.) on and off. This binary port is not affected when
other binary diagnostics interrupt unit operation.

Components and Options
Tracer UC400 Controller
The Tracer UC400 is a factory-installed BACnet® MS/TP control designed to provide control of the
fan coil (see Figure 11). The Tracer UC400 controller is designed to be used in the following
applications: as stand-alone operation, part of the Trane Tracer SC building automation system, or
part of another BACnet MS/TP Building Automation System. The Tracer UC400 can function as a
completely standalone controller in situations where a building automation system (BAS) is not
present.
The Tracer UC400 is designed to install quickly and easily into the system. Trane becomes the single
source of responsibility for the equipment, unit controls, and building automation system. As a
standalone controller, the Tracer UC400 is ideally suited for fix-on-fail replacement of units with old
pneumatic controllers, or in situations where a BAS will be added at a later date. Once power is
applied to the controller, it will automatically start up and run based upon the setpoint on the local
zone sensor. An individual time clock can be added to the unit for local scheduling. The Tracer
UC400 is BTL listed as B-ASC profile. This ensures the controller to be used with other BACnet®
building automation systems.
The Tracer UC400 controller delivers single zone VAV control and can be used in a stand-alone
application or as part of a Trane Integrated Comfort™ System (ICS).
In the stand-alone configuration, Tracer UC400 receives operation commands from the zone sensor
and/or the auto changeover sensor (on auto changeover units). The entering water temperature is
read from the auto changeover sensor and determines if the unit is capable of cooling or heating.
The zone sensor module is capable of transmitting the following information to the controller:
• Timed override on/cancel request
• Zone setpoint
• Current zone temperature
• Fan mode selection (off-auto-high-med-low)
For optimal system performance, fan coils can operate as part of an ICS building automation
system controlled by Tracer Summit. The controller is linked directly to the Summit control panel
via a twisted pair communication wire, requiring no additional interface device (i.e., a command
unit). The Trane ICS system can monitor or override Tracer UC400 control points. This includes such
points as temperature and output positions.

Features include:
• Single Zone VAV
• Automatic ventilation reset
• Filter maintenance
• Water valve override
• Freeze avoidance
• Interoperability
• Unused I/O can be used as generic I/O

Components and Options
Single Zone VAV with Fully Modulating Fan Speed
With a single zone VAV with fully modulating fan speed, and EDM with modulating signal is
required. The Tracer UC400 will minimize fan speed, and in turn energy usage, by only delivering
the air flow needed. See Figure 12.
Filter Maintenance
Filter status for the controller is based on the cumulative run hours of the unit fan. The controller
compares the amount of fan run time against an adjustable fan run hour (stored in the controller)
to determine when maintenance is recommended for the unit. The run-hours value may be user
edited as required. The valid range for the fan run hours limit is 0 to 5000 hours with a default of
600 hours. Once the run hours limit has been exceeded, the controller generates a maintenance
required diagnostic (unit will not shut-down). The user will be notified of this diagnostic through
the building automation system or when a Trane® service tool is communicating with the
controller.
Hydronic Coil Freeze Protection (Freeze Avoidance)
Fan coil systems in cold climates need to take precautions to avoid hydronic coil freeze-up. The
controller does this from three different aspects. Any of these methods of protections will result
in the unit fan being disabled, the outside air damper being shut, and the hydronic valves being
opened 100 percent.
The three methods of freeze avoidance include:
1. A binary freeze protection thermostat is mounted on the coil and will cause a latching diagnostic
if the coil temperature falls below 35°F.
2. An analog discharge air sensor monitors the temperature of the air coming off of the coil and
if the temperature falls below 40°F the outside air damper is closed, the fan is turned off and
the valves are fully opened.
3. When in the unoccupied mode, the controller has an adjustable freeze avoidance setpoint. If the
outside air temperature is below the setpoint, the unit will open the valves to allow water to flow
through the coils.
Interoperability
Interoperability allows the owner freedom to select multiple vendors, and multiple products. With
this advantage, the owner can choose the best products, the best application, and the best service
from a variety of suppliers to meet their evolving building control needs in a cost effective manner.
