Features and Benefits
The UniTrane fan-coil meets the standards of today’s market, as well as the anticipated needs of
tomorrow’s market. The tradition that company founder Reuben Trane began in the 1930s
continues with the latest generation of fan-coils from The Trane Company.
The UniTrane fan-coil is the leader in these key areas:
• Energy Efficiency
• Indoor Air Quality (IAQ)
• Controls
•Flexibility
•Quality
• Serviceability
Today’s HVAC market is concerned with issues such as indoor air quality (IAQ) and CFCs that
demand a change in HVAC products. In addition, renovation has overtaken new construction in the
fan-coil market—demanding a design that caters to renovation issues. Trane is concerned with
these issues, too. That’s why we designed the UniTrane fan-coil as an integral part of the company’s
system solutions with standard IAQ-related features that fully comply with ASHRAE 62.
Energy Efficiency
Trane’s commitment to providing premium quality products has led to the exclusive use of
Electronically Commutated Motors (ECM) in all fan coil models. These brushless DC motors
incorporate the latest technology for optimized energy efficiency, acoustical abatement,
maintenance free and extended motor life. Each motor has a built-in microprocessor that allows
for programmability, soft ramp-up, better airflow control, and serial communication.
• Trane units equipped with ECMs are significantly more efficient than the standard Permanent
Split Capacitor (PSC) motor.
• Lower operating costs on average of 50 percent (versus a PSC motor).
• The Reduced FLA feature allows units to ship with a nameplate FLA rating much lower than a
typical ECM unit.
IAQ Design
• Closed-cell insulation is standard on all units to help prevent fiberglass in the airstream.
• The main and auxiliary drain pans are constructed of a noncorrosive engineered plastic (ABS
and CyColac T).
• The main and auxiliary drain pans are positively sloped in every plane to assure proper
drainage and help maximize protection from microbial growth.
• The drain pans are removable for cleaning.
• Easy filter access encourages frequent changing.
• The auto-economizer damper option allows free cooling and ventilation to help comply with
ASHRAE 62—and save energy and operating costs.
• UniTrane fan-coils have a blow-thru design. Low vertical units are drawthru.
Controls
• This is the industry’s first solution that is factory-mounted, -wired, and -programmed for infinite
modulation of fan speed based on space loads, using the Tracer UC400. Auto Fan Speed control
with the Tracer ZN520 ramps the fan speed up and down to meet space loads.
• All controls are factory-mounted and tested to minimize field setup and improve reliability.
• Controls are wired with a 24 Vac transformer to keep only a single source power connection
requirement to the unit.

Features and Benefits
• All wall-mounted zone sensors require only low voltage control wiring from the device to the
unit control box. (No line voltage.)
• The controller automatically determines the unit’s correct operating mode (heat/cool) by
utilizing a proportional/integral (PI) control algorithm to maintain the space temperature at the
active setpoint, allowing total comfort control.
• Entering water temperature sampling eliminates the need for inefficient bleedlines to sense
automatic changeover on two-pipe changeover units.
• The random start-up feature helps reduce electrical demand peaks by randomly staggering
multiple units at start-up.
• Occupied/unoccupied operation allows the controller to utilize unoccupied temperature
setpoints for energy savings.
• Warm-up and cool-down energy features are standard with Trane controls.
• Continuous fan or fan cycling is available with Tracer ZN010 or ZN510.
• Monitor unit operation using Tracer TU building management system with Tracer ZN510 or
ZN520 and UC400.
• To customize unit control, Tracer TU or Rover™ software will allow field modification of
Tracer ZN510 and ZN520 default settings. Tracer ZN010 uses Rover to field modify default
settings. UC400 uses Tracer TU.
• Maximize fan-coil system efficiency with free cooling economizers and modulating valves on
units with Tracer ZN520 and UC400.
Flexibility
• Two, three, and four-row coils allow greater design flexibility in two and four-pipe systems.
• One-row steam or hot water reheat coils for dehumidification on units with ZN520 controls.
• Fan motors are available for either high static (0.4-inch external static pressure) or free
discharge applications.
• Piping is factory assembled, mounted and tested. Units are also available without piping.
Reheat coil piping is available on 2-pipe units with hot water reheat coils and either a fan speed
switch or Tracer ZN520 and UC400.
• Factory piping options include interconnecting piping, control valves, and end valves. Deluxe
piping also has unions and a strainer.
• Control options range from a simple fan speed switch to a DDC controller that can tie into a
Tracer Summit building automation system.
• An 8-inch extended end pocket is an available option on the piping end of cabinet style units.
• Slope-top vertical cabinet units are also available for school and dormitory applications to
prevent items from being placed on top of the units.
Quality
• Coils and piping packages are air and leak-tested before mounting on the fan-coil.
• Coil piping connections are also air and leak-tested after mounting on the unit.
• All control end devices and moving components (fans and motors) are computer-tested after
units are complete.
Serviceability
• Touch-safe control box.
• Integrated user interface with real language LED display.
• Built-in tachometer.

Features and Benefits
• Filters are easily removable and changed without removing the front panel on vertical cabinet
units.
• Motors are easy to disconnect from the fan board, allowing easy service.
• The main and auxiliary drain pans are easily removable and wipe clean with a wet cloth.
• The manual output test function is an invaluable troubleshooting tool. By simply pressing the
test button on the Tracer ZN510, ZN520, or ZN010; service personnel can manually exercise
outputs in a pre-defined sequence.

General Data
Factory-Installed Piping Packages
UniTrane fan-coils have standard piping packages available as a factory built and installed option.
Piping package options are also available for the hot water reheat coil on two-pipe units equipped
with either a fan speed switch or Tracer ZN520 and UC400 controller. Factory built assures all piping
packages are fully tested under water for leaks and are built within strict tolerances. Factory-
installed means that chilled and hot water pipes are the only field connections required. The
installer doesn’t have to sweat connect piping packages onto coil connections in a tight end pocket.
Field connections are brought to a point near the exterior of the unit for easy access. All piping and
components are located to allow condensate to drain into the auxiliary drain pan. Insulation of the
factory piping package is not required. However, all field connections should be insulated to
prevent condensation from missing the auxiliary drain pan.
Piping Package Components
UniTrane piping packages consist of a variety of components for each application. The following
section provides a detailed description of each of the piping components. Following this section
are additional illustrations and specifications.
Piping System/Placement
Factory piping systems are available for either two or four-pipe systems with right or left hand
connections. Four-pipe systems have both the heating and cooling connections on the same side
of the unit. A simple coil connection (a unit without a piping package) is also available in either a
right or left hand configuration for those applications requiring field piping.
Interconnecting Piping
Interconnecting piping refers to the copper piping which is attached to the coil connections and to
which all other components (control valves, end valves, etc.) are attached. Piping is 1/2” nominal
OD copper. Two-pipe piping extends near the unit exterior to one inlet and one outlet connection.
Four-pipe units have two sets of piping that extend near the unit exterior — one inlet and one outlet
each for both chilled and hot water. A label clearly identifies chilled and hot water connection points
on every unit.
Deluxe or Basic Piping Package
The basic piping package includes only the main components of the piping package:
interconnecting piping, control valve option, and end valves.
Figure 1. Factory-installed and -tested piping package (two-pipe deluxe package with manual
circuit setter, shown on a horizontal concealed unit)
Piping Packages
UNT-PRC001-EN.book Page 20 Tuesday, May 8, 2012 10:54 AM
UNT-PRC001-EN 21
General Data
The deluxe piping package also includes a strainer on the entering water pipe and unions at the
coil connections along with the basic components. The strainer body is cast brass construction,
with a stainless steel mesh strainer that is easily removed for cleaning. The unions are forged brass
construction and close with a minimum amount of effort.
End Valves
Each piping package includes a ball valve for the entering water pipe and one of the following end
valves on the leaving water pipe: ball valve, manual circuit setter, or an auto circuit setter. These
valves serve as the field connection points on all UniTrane piping packages.
Ball Valves. Ball valves, also known as stop or end valves, allow the unit to be cut off for service
purposes. These valves have a two-inch handle that rotates 90 percent to a fully open position. The
valve body is cast brass, and the ball is polished brass with a Teflon® seat. Ball valves are available
as end valves on both the entering and leaving water pipes.
Manual Circuit Setter
In lieu of a ball valve on the leaving water pipe, a manual circuit setter, also known as a manual flow
control valve, acts as both a flow setting device and a stop valve. This valve allows water flow
through the fan-coil unit to be set quickly and accurately.
The manual circuit setter includes Schrader ports in the valve body. These ports are used to
measure the pressure drop across the valve. This pressure drop can be compared to factory
supplied curves that relate the pressure drop to a specific flow rate. This valve also has a memory
stop so the correct setting can be found quickly.
Auto Circuit Setter
An auto circuit setter is an automatic flow control device available on the leaving water pipe. The
auto circuit setter includes a cartridge within the valve body that is sized to allow a specific flow
rate through the coil. This valve sets flow through the coil without any action required by a system
piping balancer. The auto circuit setter is available on the leaving water pipe with a ball valve. The
auto circuit setter also includes two P/Ts plugs in the valve body to allow measurement of the
pressure drop temperature through the valve.
Control Valves
Piping packages are available with or without control valves. All control valve options are factory
mounted and wired to the UniTrane fan-coil controls.
Tw o - Wa y / Tw o - P o s i t i o n Va l v e s
These valves will either fully open or close in response to a 24 Vac signal from the Trane controller.
Main control valves are direct-acting valves, while the auxiliary valves are reverse-acting. All
control valves are factory mounted in the leaving water pipe downstream of the coil. Some means
of relieving pump head pressure should be accounted for when two-way valves are selected.
Normally open or normally closed valves are available.
Three-Way/Two-Position Valves
These valves will either allow full water flow through the coil or divert the flow through a bypass
line. The valves respond to a 24 Vac signal from the Trane controller. Main control valves are direct
acting valves, while the auxiliary valves are reverse-acting. All three-way valve packages include
a balance fitting in the bypass line to allow flow balancing in the bypass position. Three-way valves
are factory mounted in the leaving water pipe downstream of the coil. Normally open or normally
closed valves are available.
Two-Way Modulating Valves
These valves modulate the water flow through the coil in response to a signal from the Trane
controller. All modulating valves are three-wire floating point equal percentage valves. The
modulating valves are factory mounted in the leaving water pipe downstream of the coil.

General Data
Three-Way Modulating Valves
These valves modulate the water flow through the coil in response to a signal. Three-way valves
allow water that is directed through the coil to mix with water that is directed through the bypass
line. This mixture exits through the leaving water pipe. All modulating valves are three-wire
floating point equal percentage valves. The modulating valves are factory mounted in the leaving
water pipe downstream of the coil.

General Data
Selecting the Correct Modulating Valve Size
Modulating valves are available in any of four port sizes. The port sizes relate to a Cv of 0.6, 1.1, 2.3,
2.7, 3.3, and 3.8, which is the coefficient of flow. The coefficient of flow is defined as the volume of
water flow through a control valve in the fully open position with a 1 psig differential across the
valve. It is calculated using the following formula:
Cv = Q/Square root ΔP where:
Cv = flow coefficient
Q = flow rate (Gpm)
ΔP = pressure drop across the valve or coil (psig).
For good control, the valve Cv should be approximately equal to the Cv of the water coil.
Modulating Valve Selection Example
Assume a size 06 fan-coil is selected to operate at the following conditions:
Vertical Cabinet Fan-Coil
Entering water temperature = 45°F
Leaving water temperature = 55°F
EAT conditions = 80/67.
The coil is selected as a four-row coil.
Select the best modulating valve size for this unit.
1. Fi nd th e ΔP across the water coil. Refer to the AHRI performance table to determine the ΔP
across the water coil (or use TOPSS™ selection program). The water pressure drop is found to
be 7.0’ of water at a flow rate of 3.74 gpm. This converts to a pressure drop of 3.03 psig (1.0 feet
of water = 0.4328 psig.)
2. Calculate the Cv of the water coil.
Cv = Gpm/Square root ΔP
Cv = 3.74/Square root 3.03
Cv = 2.15
Therefore, the valve with the Cv of 2.7 should be selected since it has the Cv which is closest
to the Cv of the water coil. The following tables illustrate possible valve selections at AHRI
conditions for horizontal concealed units with a high static motor and vertical cabinet units with
a free discharge motor.
Note: Do not use these tables for any applications other than vertical cabinet or horizontal
concealed units at AHRI conditions.

The Electronically Commutated Motor (ECM) engine controls and reports the performance of up
to two Trane Brushless DC (BLDC) motors.
• The engine also coordinates the operation of the fan in response to electric heat behavior and
electric behavior in response to hydronic heat behavior.
• The engine incorporates a user interface that allows adjustment of certain unit parameters and
provides constant feedback on motor operation.
• The engine integrates service and troubleshooting tools.
• The engine integrates a versatile configurable auxiliary temperature sensor.
• The engine incorporates various safety and lockout features, such as maintaining proper fan
speeds if electric heat is called for.
Status Display
The ECM engine board contains a four-digit, seven-segment display that is used to present

The adapter allows direct customer interfacing through the use of terminal strips. Standard
interfacing includes:
• Fan Speeds (H, M, L) (for wall mounted fan speed switches)
• Variable speed (0–10V) inputs
The standard adapter board eliminates many separate wiring harnesses in the panel and allows
simple, mistake-proofed single-plug interfacing of:
• The ECM engine controller
•Transformers
•Motors
• Valves
•Dampers
• Electric heat control
• Fan speed switches
• Main power (except electric heat)
The manual fan mode switch is available for fan-coil units that do not have Trane factory-mounted
control packages. This four-position switch (off, high, medium, low) allows manual fan mode
selection and is available unit or wall mounted. The unit-mounted option (Digit 31 = D) operates
on line voltage. The wall-mounted option (Digit 31 = K) is low-voltage and has three 24-volt relays
using a factory-wired transformer and relays to control the fan motor.

The control interface is intended to be used with a field-supplied, low-voltage thermostat or
controller. The control box contains a relay board which includes a line voltage to 24-volt
transformer, quiet contactors (for electric heat units), and an optional disconnect switch. All end
devices are wired to a low-voltage terminal block and are run-tested, so the only a power
connection and thermostat connection is needed to commission the unit. Changeover sensors and
controls are provided whenever a change-over coil is selected. When N.O. valves are selected,
inverting relays are provided for use with standard thermostats.
The CSTI adapter board provides all the hookups of the standard adapter board, but in addition,
provides hookups for valve control (main and auxiliary coils), electric heat control, and damper
control. Screw terminal blocks provide convenient access to fan controls and to end device control.
In addition, a courtesy 10-Vdc supply is provided for use with an external potentiometer or rheostat.
The 10-Vdc supply supports up to 10 mA draw.
Tracer Controls
The Tracer family of controllers, ZN010, ZN510, ZN520, and UC400 offer the combined advantages
of simple and dependable operation with the latest Trane-designed controller. Standard control
features include options normally available on more elaborate control systems. All control options
are available factory-configured or can be field-configured using Rover service software, the UC400

Tracer ZN510, Model Number Digit 30 = F
ZN510 can be used as either a stand-alone or communicating microprocessor controller.
Tracer ZN520, Model Number Digit 30 = G
The ZN520 controller can be used in a stand-alone application or as part of a Trane Integrated
Comfort™ System (ICS).
In the stand-alone configuration, ZN520 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-coil units can operate as part of an Integrated Comfort
System (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 ZN520
control points. This includes such points as temperature and output positions.
Rover Service Software
This windows-based software package option allows field service personnel to easily monitor,
save, download, and configure Tracer controllers through a communication link from a portable
computer. When connected to the communication link, Rover can view any Tracer controller that
is on the same communication link.

Sequence of Operation
Fan Speed Switch
Off: Fan is turned off, two-position damper option spring-returns closed.
High, Medium, Low: Fan runs continuously at the selected speed. The two-position damper option
opens to an adjustable mechanical stop-position.
Tracer ZN010 and ZN510
Off: Fan is off; control valves and fresh air damper option close. Low air temperature detection
option is still active.
Auto (Fan Cycling): Fan and fresh air damper cycle with control valve option to maintain setpoint
temperature. In cooling mode, the fan cycles from off to medium and in heating mode it cycles from
off to low (factory default that can be field-adjusted using Rover service software). When no heating
or cooling is required, the fan is off and the fresh air damper option closes. The fan can also be field-
configured (using Rover) to run at a defined speed when the fan speed switch is in the auto position.
Low, Medium, High (Continuous Fan): Fan operates continuously while control valve option cycles
to maintain setpoint temperature. Fresh air damper option is open.
Tracer ZN520
Off: Fan is off; control valve options and fresh air damper options close. The low air temperature
detection option is still active.
Auto: Fan speed control in the auto setting allows the modulating (three-wire floating point) control
valve option and three-speed fan to work cooperatively to meet precise capacity requirements,
while minimizing fan speed (motor/energy/acoustics/dehumidification) and valve position (pump
energy/chilled water reset). As the capacity requirement increases at low fan speed, the water valve
opens. When the low fan speed capacity switch point is reached, the fan switches to medium speed
and the water valve repositions to maintain an equivalent capacity. The reverse sequence takes
place with a decrease in required capacity.
Low, Medium, High: The fan will run continuously at the selected speed and the valve option will
cycle to meet setpoint.
Tracer UC400
Occupied Mode
In Occupied Mode, the UC400 controller maintains the space temperature based on the occupied
space temperature setpoint ± occupied offset. The controller uses the occupied mode as a default
mode when other forms of occupancy request are not present and the fan runs continuously. The
outdoor air damper, if present, will close when the fan is OFF. The temperature setpoints can be

Controls
local (hard wired), communicated, or stored default values (configurable using the Tracer TU
service tool).
Unoccupied Mode
In unoccupied mode, the UC400 controller attempts to maintain the space temperature based on
the unoccupied heating or cooling setpoint. The fan will cycle between high speed and OFF. In
addition, the outdoor air damper remains closed, unless economizing. The controller always uses
the stored default setpoint values (configurable using the Tracer TU service tool), regardless of the
presence of a hard wired or communicated setpoint value.
Timed Override Control
If the UC400 controller has a timed override option (ON/CANCEL buttons), pushing the ON button
initiates a timed override on request. A timed override on request changes the occupancy mode
from unoccupied mode to occupied bypass mode. In occupied bypass mode, the controller
controls the space temperature based on the occupied heating or cooling setpoints. The occupied
bypass time, which resides in the UC400 controller and defines the duration of the override, is
configurable from 0 to 240 minutes (default value of 120 minutes). When the occupied bypass time
expires, the unit transitions from occupied bypass mode to unoccupied mode. Pushing the
CANCEL button cancels the timed override request. In addition, it will end the timed override
before the occupied bypass time has expired and transition the unit from occupied bypass mode
to unoccupied mode.
If the controller is in any mode other than unoccupied mode when the ON button is pressed, the
controller still starts the occupied bypass timer without changing to occupied bypass mode. If the
controller is placed in unoccupied mode before the occupied bypass timer expires, the controller
is placed into occupied bypass mode and remains in this mode until either the CANCEL button is
pressed on the Trane zone sensor or the occupied bypass time expires.
Zone Temperature Control
The UC400 controller has three methods of zone temperature control:
•Cascade zone control—used in the occupied, occupied bypass, and occupied standby
modes. It maintains zone temperature by controlling the discharge air temperature to control
the zone temperature. The controller uses the difference between the measured zone
temperature and the active zone temperature setpoint to produce a discharge air temperature
setpoint. The controller compares the discharge air temperature setpoint with the discharge air
temperature and calculates a unit heating/cooling capacity accordingly (refer to the illustration
below). The end devices (outdoor air damper, valves, and so on) operate in sequence based on
the unit heating/cooling capacity (0–100 percent).
If the discharge air temperature falls below the discharge air temperature low limit setpoint,
(configurable using the Tracer TU service tool), and the cooling capacity is at a minimum, the
available heating capacity is used to raise the discharge air temperature to the low limit.
•Simplified zone control— if discharge air temperature failure occurs, then simplified zone
controls runs. In the unoccupied mode, the controller maintains the zone temperature by

calculating the required heating or cooling capacity (0–100%) according to the measured zone
temperature and the active zone temperature setpoint. The active zone temperature setpoint
is determined by the current operating modes, which include occupancy and heat/cool modes.
•Discharge air temperature control— is the backup mode that runs only if there is not valid
zone temperature. In this mode, the active space temperature setpoint is used as the discharge
air temperature setpoint.
Important: This is not a normal operating mode. The source of the invalid zone temperature
needs to be corrected to restore normal operation.

Binary inputs -- there is also a defrost and fan status (for 1,2,3 speed fans) for UC400 and ZN520.
The ECM fan does not use the Binary input for fan status but gets the info over IMC from the ECM.
ZN520 also had a binary input for fan status. ZN520 also had defrost but it was wired directly to the compressor (IOP
explains this).

Control Features
The following control functions are standard features on units with Tracer ZN010, ZN510, ZN520,
or UC400.
Entering Water Temperature Sampling Function
A system that uses a two-way control valve option might not sense the correct entering water
temperature during long periods when the control valve is closed. If the demand for heating or
cooling does not exist for a long period, the entering water will eventually approach ambient
temperature.
Using the entering water temperature sampling function, the controller provides accurate two-pipe
system changeover—without sacrificing the benefits of two-way control valves. Also, it eliminates
inefficient bleed or bypass lines that can allow unnecessary waterflow through the system.
This function periodically samples the entering water temperature by opening the hydronic valve.
The valve opens for 20 seconds to allow the water temperature to stabilize. Then the controller
reads the entering water temperature for up to three minutes to see if the correct water temperature
is available for the selected operating mode.
The entering water temperature must be five degrees or more above the space temperature to
allow hydronic heating and five degrees or more below the space temperature to allow hydronic
cooling. If the correct water temperature for the operating mode is available, the unit begins normal
heating or cooling operation. If the correct water temperature is not available, the controller closes
the control valve and waits 60 minutes before attempting to sample the entering water temperature
again.
A factory-mounted thermistor senses the entering water temperature on changeover
cooling/heating coil units. If the fan-coil has a factory-mounted piping package, the sensor is
strapped to the entering water pipe. If the fan-coil does not have a piping package, the sensor is
coiled in the end pocket for mounting on customer-supplied piping. This sensor must detect
accurate water temperature for proper changeover.
Automatic Heat/Cool Mode Determination
The controller automatically determines whether heating or cooling is needed—based on space
and system conditions. Utilizing a proportional/integral (PI) control algorithm to maintain the space
temperature at the active heating or cooling setpoint. The controller measures the space
temperature and active setpoint temperature to determine the unit’s heating or cooling capacity
(zero to 100 percent).
Occupied/Unoccupied Operation
The occupancy input utilizes a binary switch (i.e. motion sensor, timeclock, etc.) that allows the zone
sensor to utilize its unoccupied internal setpoints.
Random Start
This feature randomly staggers multiple unit start-up to reduce electrical demand spikes.
Warm-up
The two-position fresh air damper option closes during the occupied mode when the space
temperature is three degrees or more below the heating setpoint temperature. The damper
remains closed during warm-up until the space temperature is within two degrees of the heating
setpoint temperature.
Cool-down
The two-position fresh air damper option closes during the occupied mode when the space
temperature is three degrees or more above the cooling setpoint temperature. The damper
remains closed during cool-down until the space temperature is within two degrees of the cooling
setpoint temperature.

Manual Output Test Function
NA on UC400. But will have ability through TU. This feature is an invaluable tool for
troubleshooting a unit. By simply pressing the controller’s test button, service personnel can
manually exercise outputs in a pre-defined sequence.
Peer to Peer Communication (Tracer ZN510, ZN520, and UC400)
Peer to peer communication allows multiple units in one space to share the same zone sensor and
provide simultaneous heating and cooling. The Tracer ZN510 or ZN520 controller can share
information between units on the same communication link using a twisted pair wire in the field.
Unit configuration must be modified with Rover service tool. On the UC400, zone sensor data
sharing can be accomplished by use of the BAS system controller.
Economizing Control (Tracer ZN520)
With the controller configured for economizing control, it will calculate the required cooling
capacity every ten seconds and modulate the damper option open to the calculated position. If the
setpoint is not satisfied, the damper will continue to open until the setpoint condition has been met
or the damper is 100 percent open. If this still does not satisfy the setpoint, the cooling valve option
will begin to open and try to satisfy the load requirements. Once capacity exceeds the load
requirements, the valve will begin to close until the setpoint has been reached or the damper
reaches its minimum position, which is field-adjustable. This option uses a three-wire, floating
point damper actuator.
A thermistor to sense discharge air is factory mounted near the discharge surface of the last coil
for use in economizing and cascade temperature control. Tracer Summit can also utilize this
temperature value as a read-only point. Cascade temperature control uses both the zone and
discharge air temperatures to more accurately calculate the required unit capacity.
A thermistor to sense fresh air is factory mounted at the unit’s fresh air opening for use in
economizer applications or as a read-only point for Tracer Summit. If the fresh air temperature is
a read-only value, it will not impact the control algorithm. In an economizer application, a fresh air
temperature signal must be provided either by this thermistor or Tracer Summit.

Controls
Tracer ZN520 and UC400 Additional Features
Automatic Fan Speed Adjustment
When configured in the AUTO mode, the fan operates at the lowest speed possible (high, medium,
or low) to maintain space temperature. As the cooling load decreases, the controller switches the
fan to operate at the next lower speed, and the control valve modulates the unit’s cooling capacity
as required. This results in less fan energy use, improved dehumidification performance, and lower
sound levels.
Automatic Ventilation Reset
To ensure proper ventilation rates, the controller is configured with two fresh air damper minimum
position setpoints for occupied operation. As the fan speed changes to low or high, the damper
adjusts to maintain the correct ventilation rate for the space. The damper position does not adjust
when the fan speed changes to medium.
Fan Status
Tracer ZN520 and UC400 monitors the fan output status to determine if the fan is operating.
Filter Maintenance Status
The controller has an adjustable timer that indicates through Summit, Rover (ZN520) or TU (UC400)
when filter maintenance is necessary. Filter maintenance status is based on cumulative fan run
hours.
Dehumidification
When the fan-coil unit is equipped with a reheat coil and humidity sensor, the controller will
independently control both space temperature and humidity. If the space humidity level rises
above the upper limit, the capacity of the cooling coil is increased, overcooling the air to maintain
the space humidity below the upper limit. Then, the capacity of the heating coil modulates, adding
a small amount of heat to temper (reheat) the air and avoid overcooling the space.
Water Valve Override
The water valve override function drives all water valves in every unit fully open simultaneously.
This helps reduce the time required for waterside balancing.
Cascade Control
The controller maintains discharge air temperature using a cascade control algorithm. The
discharge air temperature is based on the difference between the space temperature and setpoint.
Unit capacity modulates to achieve the discharge air temperature.
Interoperability
Tracer ZN520 can be used with a Tracer Summit system or on other control systems that support
LonTalk and the SCC profile. For more information on specific inputs and outputs, see the
Installation, Owner, and Maintenance Manual, UNT-IOM-6. UC400 can be used with a Tracer
Summit system or other control systems that support BACnet. For more information on specific
inputs and outputs, see the Installation, Owner, and Maintenance Manual, UNT-SVX07D-EN.

End Device Options
All end device options are factory-installed and -tested.
Two-Position Control Valves, Model Number Digits 27 and 28 = A - H
Two-position valve options are available with either Tracer ZN010, ZN510, ZN520 or UC400. Valves
are spring-return type, sweat connections, and available as normally open or closed. The valves
respond to a 24 V signal and have 1/2-inch sweat connections. The two-way valve option will either
fully open or close. The three-way valve option allows either full water flow through the coil or
diverts waterflow through the bypass. If the control valve loses power, the valve returns to its de-
energized position. All control valve options are factory installed in the leaving water piping
downstream of the hydronic coil. The valve actuator is easily removable for service without
removing the valve body from piping.
Modulating Control Valves (Tracer ZN520 and UC400), Model Number Digits 27
and 28 = J - R
These 1/2-inch sweat connect valves are three-wire floating point valves, equal percentage type.
Modulating valves are available in four Cv sizes: 0.7, 1.5, 2.5, and 4.0. The valve responds to a 24 V
triac signal from the controller, which determines the valve position by a control algorithm. If the
valve loses power, it remains in the position that it was in when the power loss occurred. All control
valves are factory installed in the leaving water piping downstream of the hydronic coil.
Field-Supplied Valves, Model Number Digits 27 and 28 = X, Y, or 1
This option allows the controller to be factory-configured for the normal position of the field-
supplied valve, as well as running a wiring harness from the control box to the piping side of the
unit. When the field supplied valve option is chosen, the control box is provided with low voltage
components and wired back to a terminal strip (CSTI) or controller.
Note: The Trane Company does not recommend wild coil applications.

Two-Position Fresh Air Damper Actuator, Model Number Digit 13 = D, E, or F
(Available with all control options except ZN520)
This damper actuator uses a 24 V signal and is factory-wired and mounted to the damper assembly.
It allows zero to 50 percent fresh air. The damper will drive open to an adjustable mechanical stop-
position whenever the fan is running during occupied mode and will spring-return closed when the
fan turns off.
Note: Trane recommends using the low temperature detection option with fresh air dampers to
detect possible freeze conditions.

Controls
This option is a three-wire floating point, spring-return damper actuator and is factory-wired and
mounted to the damper assembly. When the controller enables the economizer and the unit is in
occupied mode, the fresh air damper modulates between its minimum position (editable) and the
full open position to maintain setpoint temperature. If economizer operation stops or if the unit is
in the heating mode, the fresh air damper adjusts to its minimum position.
Note: Trane highly recommends using the low temperature detection option with a fresh air
damper to detect possible freeze conditions.
Low Temperature Detection, Model Number Digit 36 = 2
When the low temperature detection device senses an entering air temperature of 36°F to the
hydronic coil, the normally-closed switch opens a corresponding set of binary input terminals. The
fan disables, control valves open, and the fresh air damper closes.
Thirty minutes after the diagnostic, Tracer ZN010, ZN510, or ZN520 uses an automatic reset
function to attempt to reset the unit. If the diagnostic occurs again within 24 hours after an
automatic diagnostic reset, the unit will require a manual reset. This function attempts to resolve
the infrequent nuisance alarm.
The low temperature detection device is an averaging type capillary tube and will reset when it
detects an entering air temperature of at least 44°F.
Condensate Overflow Detection, Model Number Digit 35 = 2
A float switch is factory-supplied for field installation in the auxiliary drain pan to detect a high
condensate water level. When the float switch rises, the normally closed input opens a
corresponding set of binary input terminals. This also causes the fan to disable, and the control
valve and fresh air damper options to close. Although the float switch will close when the high
condensate level recedes, the controller must be manually reset before normal unit operation can
occur. If using a Tracer ZN510, ZN520 or UC400 controller you can reset using Tracer Summit. Use
Rover service software to reset units with Tracer ZN010, ZN510, or ZN520 and Tracer TU for units
with a UC400.

Mechanical Specifications
Motors
All motors are brushless DC (BLDC)/electronically commutated motors (ECM) factory-
programmed and run-tested in assembled units. The motor controller is mounted in a touch-safe
control box with a built-in integrated user interface and LED tachometer. If adjustments are needed,
motor parameters can be adjusted through momentary contact switches accessible without
factory service personnel on the motor control board.
Motors will soft-ramp between speeds to lessen the acoustics due to sudden speed changes.
Motors can be operated at three speeds or with a field-supplied variable speed controller. The
motor will choose the highest speed if there are simultaneous/conflicting speed requests.
All motors have integral thermal overload protection with a maximum ambient operating
temperature of 104°F and are permanently lubricated. Motors are capable of starting at 50 percent
of rated voltage and operating at 90 percent of rated voltage on all speed settings. Motors can
operate up to 10 percent over voltage.
Controls
Controls options are: fan speed switch, control interface, and Tracer ZN010, ZN510, ZN520, and
UC400. A variety of inputs and outputs are available for the control interface and Tracer controller
options. A disconnect switch (for non-electric heat units), fused transformer, contactor(s), and
terminal strip are provided with the control interface and Tracer controller options. For specifics on
Tracer ZN010, ZN510, ZN520, and UC400, please refer to “Controls,” p. 39.
Control Interface
The control interface is intended to be used with a field-supplied, low-voltage thermostat or
controller. The control box contains a relay board which includes a line voltage to 24-volt
transformer, quiet contactors (for electric heat units), and an optional disconnect switch. All end
devices are wired to a low-voltage terminal block and are run-tested, so the only a power
connection and thermostat connection is needed to commission the unit. Changeover sensors and
controls are provided whenever a change-over coil is selected. When N.O. valves are selected,
inverting relays are provided for use with standard thermostats.
Fan Speed Switch
The fan speed switch is available with or without the control interface option and is available as
wall-mount or unit-mount. Both the wall-mount and unit-mount FSS will employ low-voltage fan
switches. However, the low-voltage fan speed option will provide an interface to factory wiring,
including variable speed/high-medium-low (HML) control. The control box contains a line voltage
to 24-volt transformer, ECM motor controller, and an optional disconnect switch.
