Warranty
Warranty is based on the general
terms and conditions of the
manufacturer. The warranty is void
if the equipment is repaired or
modified without the written
approval of the manufacturer, if the
operating limits are exceeded or if
the control system or the electrical
wiring is modified. Damage due to
misuse, lack of maintenance or
failure to comply with the
manufacturer's instructions or
recommendations is not covered by
the warranty obligation. If the user
does not conform to the rules of
this manual, it may entail
cancellation of warranty and
liabilities by the manufacturer.
Refrigerant
The refrigerant provided by the
manufacturer meets all the
requirements of our units. When
using recycled or reprocessed
refrigerant, it is advisable to ensure
its quality is equivalent to that of a
new refrigerant. For this, it is
necessary to have a precise analysis
made by a specialized laboratory. If
this condition is not respected, the
manufacturer warranty could be
cancelled.
Storage
Take precautions to prevent
condensate formation inside the
unit's electrical components and
motors when:
1. The unit is stored before it is
installed; or,
2. The unit is set on the roof curb
and temporary auxiliary heat is
provided in the building.
Isolate all side panel service
entrances and base pan openings
(e.g., conduit holes, S/A and R/A
openings, and flue openings) to
minimize ambient air from entering
the unit until it is ready for start-up.
Do not use the unit's heater as
temporary heat without completing
the start-up procedures detailed
under "Unit Start-Up".
The Trane Company will not assume
responsibility for equipment
damage resulting from
accumulation of condensate on the
unit electrical components.
Maintenance contract
It is strongly recommended that you
sign a maintenance contract with
your local Service Agency. This
contract provides regular
maintenance of your installation by
a specialist in our equipment.
Regular maintenance ensures that
any malfunction is detected and
corrected in good time and
minimizes the possibility that
serious damage will occur. Finally,
regular maintenance ensures the
maximum operating life of your
equipment. We would remind you
that failure to respect these
installation and maintenance
instructions may result in
immediate cancellation of the
warranty.
Training
To assist you in obtaining the best
use of it and maintaining it in
perfect operating condition over a
long period of time, the
manufacturer has at your disposal a
refrigeration and air conditioning
service school. The principal aim of
this is to give operators and
technicians a better knowledge of
the equipment they are using, or
that is under their charge. Emphasis
is particularly given to the
importance of periodic checks on
the unit operating parameters as
well as on preventive maintenance,
which reduces the cost of owning
the unit by avoiding serious and
costly breakdown.

Installing the unit
Discharge Conversion
If a unit is to be converted to
Vertical discharge, a panel must be
acquired from Trane.
If a unit is to be converted to
Horizontal discharge, the following
conversion must be performed:
1. Remove the return and supply
duct covers.
2. Apply gasket to the return duct
cover.
3. Position duct covers as shown in
Figure 4. The supply duct cover is
installed (insulation side down)
over the downflow return
opening by engaging one side of
the panel under a retaining angle
and securing the other side with
3 screws.
4. Slide return duct cover
(insulation side up) into supply
openings until outer edge of the
duct cover engages with the two
retaining clips on the duct
flanges. Secure the outer edge of
the each duct cover with two
screws.
Figure 5 - Conversion to horizontal
discharge
1 = Supply duct cover, insulation side
down
2 = Return duct cover with gasket
installed, insulation side up
3 = Edge of duct cover goes under
retaining angle
Unit mounting on roof
Fix the rooftop curb on the joint
beam of the building's structure.
Make the rooftop curb's sealing
surface level using angle brackets
adjusted by screw bolts, located
around its perimeter. Place the
adhesive seals on the curb's sealing
surface (perimeter and cross
pieces). Make the rooftop leak-tight
around the curbs before installing
the unit, in compliance with current
construction standards.
Note:The unit must be installed
perfectly level to ensure
condensates flow from the
condensate tray.
The rooftop unit nests into the curb
and is supported by it. Position the
unit, taking care to comply with the
indicated directions: the unit's
discharge and intake openings must
match those of the curb.

RT-SVX20A-E410
Installing the unit on the ground
To install the unit on the ground, its
base must be level and supported
securely. For horizontal discharge
units, a support is required such as
a metal or concrete slab whose
height must be determined
according to the amount of snow
cover, to prevent problems with
condensation drainage and
obstruction of the external coil. If
necessary use an anti-vibration
material between the rooftop unit's
base and the support.
Note: Unit installation must comply
to local codes
Connection of duct
network
1) Downflow discharge units
(TSD,WSD,YSD)
Using the rooftop curb
The rooftop curb must be
insulated on the outside walls at
the discharge and intake
openings to prevent
condensation in the ducts.
The rims around the discharge
and intake openings make it
possible to attach the flanges on
the ends of the ducts. If you are
using rigid duct ends
recommended on the rooftop
curb plan, it is essential to fix
these components before
installing the unit.
For the design of the duct
network, comply with
recommendations currently
applicable on the market, in
particular:
. Installation of a section of
flexible ducts to limit
transmission of the unit's
vibrations
. Use of movable vanes or
deflectors to reduce the sound
level.
2) Horizontal discharge units
(TSH,WSH,YSH)
The intake and discharge ducts
must be insulated (thermal
insulation).
The duct section located outside
must be leak-tight.
Provide a flexible connector to
prevent transmission of the unit
vibrations. This flexible duct
must be installed inside the
building.
Note: In case of use of units with
economizer option, temperature
and humidity sensors must be
installed in return duct.
Economizer linkage is factory
mounted but the damper position
must be adjusted on site.

Gas pipework installation
The installation must conform to all
standards and regulations.
The gas supply pipework and gas
stop valve to be installed near the
unit must be sized so as to ensure
the gas pressure is sufficient at the
unit inlet when operating at full
load.
CAUTION! Should the pressure at
the unit valve gas inlet be higher
than 0.035 bar, an expansion valve
must be installed.
The pipework must be self-
supporting and the final connection
to the burner must be made by a
flexible pipe. Provide a dust
protection (filter) upstream the unit
connection.
CAUTION!The gas pipework must
not exert any stress on the burner
gas connection.
Note: Expansion valve must be
adapted to the type of gas used:
G 20: 20 mb
G 25: 25 mb
G 31 (Propane): 37 or 50 mb
Table 6 - Gas burner models
See Table 51 for burner
performance.
Gas leak check procedure
1. Vent the gas line
2. Gas supply line pressure test:
close valve 4 and open valve 2
3. Leak-check the gas pipe.
Look for gas pipe leaks using
"Typol", "1000 bulles" or a similar
product. Do not use soapy water.
WARNING! Never use an open

Supply fan adjustment
Use the following procedure to
determine the proper adjustment of
the supply fan for a specific
application.
1. Determine total external static
pressure about system and
accessories.
Obtain the design airflow rate
and the design external static
pressure drop through the
distribution system.
Add static pressure drop of the
accessories installed on the unit.
(Table 9)
Add the total accessory static
pressure drop (from step 1b) to
the design external static
pressure (from step 1a). The sum
of these two values is the total
system external static pressure.
2. Using the Tables 10 through 35 to
find the external static pressure
that most closely approximates
total system external static
pressure. Then locate the
appropriate airflow rate for your
unit. The value obtained
represents the brake horsepower
for the supply fan motor and the
fan RPM.
3. Adjust motor sheave according
to Table 8.
Installation
15RT-SVX20A-E4
To adjust belt
The fan belts must be inspected
periodically to assure proper unit
operation. Replacement is
necessary if the belts appear frayed
or worn.
Units with dual belts require a
matched set of belts to ensure equal
belt length.
When removing or installing the
new belts, do not stretch them over
the sheaves. Loosen the belts using
the belt tension adjustment bolts on
the motor mounting base.
Once the new belts are installed,
adjust the belt tension.

Electrical connection
The electric panel is located in the
unit compressor section. Remove
the compressor access panel. The
unit is designed to run with 400 V
+/- 5%/50 Hz/ 3 ph.
Factory supplied disconnect switch
(option)
The disconnect switch is factory
mounted. It is located in the
compressor section. Mount the
disconnect switch onto the exterior
of the unit, between the condenser
coil and the electrical panel (near
the unit top corner). Wire the
disconnect switch from the power
terminal block in the panel to the
disconnect switch with the wire
bundle provided by following the
electrical diagram found in the unit.
Figure 13 - Power supply
1 = Power supply
1
Over current protection
The branch circuit feeding the unit
must be protected in accordance
with national or local codes and
maximum unit amps indicated in
Table 36.
Power wiring
The unit's power supply must be
provided by 4-wire cable with cross-
sectional areas complying with
legislation.
The power supply cables must be
laid in leak-tight pipes and pass
through the bottom of the electric
panel for units without electric
heaters and through the heat
section when electric heater option
is selected. The cables must not be
taut.
Appropriate connectors must be
provided. Flexible pipe supports are
required to prevent noise
transmission in the building's
structure. Ensure all the connections
are tightened.
Note:
1. Earthing must be executed in
compliance to national and local
legislation.
2. The machines are designed for a
short-circuit current of 10 kA. In
the event of a higher application,
contact your local sales office.
Compressor electrical phasing
Proper phasing of the electrical
power wiring is critical for proper
operation and reliability of the scroll
compressor and fans.
Proper rotation of the scroll
compressor must be established
before the unit is started. This is
accomplished by confirming that
the electrical phase sequence of the
power supply is correct. The motor
is internally connected for clockwise
rotation with the inlet power supply
phased A,B,C.
The direction of rotation may be
reversed by interchanging any two
of the line wires. It is this possible
interchange of wiring that makes a
phase sequence indicator necessary
if the operator is to quickly
determine the phase rotation of the
compressor motor.
Installation
31RT-SVX20A-E4
The "ABC" indicator on the face of
the phase indicator will glow if
phase is ABC for terminals L1, L2,
L3.
IMPORTANT! After completion of
wiring, check all electrical
connections, and ensure all
connections are tight. Replace and
secure all electrical box covers and
access doors before leaving unit or
connecting power to circuit
supplying the unit.
CAUTION! Units with scroll
compressors are not equipped with
crankcase heaters.
WARNING! Disconnect all power,
including remote disconnects, and
discharge all capacitors before
servicing.
Follow proper lockout/tagout
procedures to ensure the power
cannot be inadvertently energized.
After power is removed, allow
4 minutes for capacitors to
discharge. Verify with an
appropriate voltmeter that all
capacitors have discharged. Failure
to disconnect power and/or
discharge capacitors before
servicing could result in death or
serious injury. For additional
information regarding the safe
discharge of capacitors, see Trane
Service Bulletin PROD-SVB06A.

good air circulation,
approximately 1.4 m from the
floor.
2. Remove the back plate from the
sensor and thread the power
wires and output signal wire
through the hole in the back
plate (Figure 17).
For surface wiring, make cut-
outs with pliers to the thinner
section of the upper or lower
edge of the back plate and to
thread the wires through.
3. Mount the back plate to the wall
with screws. Note that the arrow
on the back plate shows the
mounting direction.
4. On the circuit board, use the two
jumpers next to the terminal
block to set up the type of output
(0-10 Vdc) (Figure 18).
5. Insert the circuit board in the

Hot water coil
(Down flow units only)
In order to prevent water to freeze
up in the coil during unoccupied
period or shutdown limited period,
a thermostat opens when there is a
risk of freeze-up. The services of a
water treatment specialist are
recommended if water used can
cause scaling deposits or erosion.
Insulate all the water piping likely to
be exposed to freezing
temperatures in order to avoid
freeze up of the coil and heat
losses. The water distribution
network must be fitted with vents in
places where air is likely to be
trapped.
The hot water coil is factory
mounted in the discharge section.
Two holes are provided to connect
the hot water coil. They are located
at the base of the unit. Remove the
central panel to access the coil,
using an 8 mm wrench (the bolts
are located on the bottom part of
the panels). The tubes for entering
and leaving water are equipped
with a threaded female connector.
Water connection inlet/outlet:
1 ¼" ISO R7.
Installation and connection
In order to prevent water to freeze
up in the coil during unoccupied
period or shutdown limited period,
it is recommended to use ethylene
glycol. The services of a water
treatment specialist are
recommended if water used can
cause scaling deposits or erosion.
Insulate all the water piping likely to
be exposed to freezing
temperatures in order to avoid
freeze up of the coil and heat
losses. The water distribution
network must be fitted with vents in
places where air is likely to be
trapped.

Electric Heater
Electric heaters are fitted on the fan
discharge.
Heaters have two heating stages
and provided with two types of
overheat thermostats:
Automatic reset thermostats
which stop the electric heater
when the air temperature rises to
76°C. Automatic reset at 60°C. No
alarm output available.
The manual reset thermostat
which stop the unit when the air
temperature rises to 120°C. No
alarm output available.
Soft Starter
The soft starter is used to achieve a
progressive supply fan start and a
reduced starting current as well as
the motor starting torque. This
option is well adapted for textile
duct applications. It is factory
installed in the main control panel.
The soft starter gradually increases
the voltage of the supply fan motor
until it reaches full line voltage.
The starting time can be adjusted
from 0 to 40 seconds but the soft
starter is factory set to the
maximum starting time value,
40 seconds.

0 - 25% fresh air hood
The 0-25% fresh air hood allows to
introduce fresh air into the unit.
This is a manual device fitted on the
back of the unit, sized for a
maximum of 25% of the nominal
rooftop air flow.
This option includes for the hood
itself, a wire mesh and a slidable
damper.
The slidable damper has to be
adjusted manually by removing the
screws and sliding it off up or down
(Figure 28).
The amount of fresh air introduced
is then permanently fixed.

Barometric relief
The barometric relief allows to
minimize overpressure in the
building caused by the introduction
of fresh air. This option is typically
installed when fresh air intake is
below 25% of the nominal air flow
and when the return air pressure
drop is below 25Pa.
This option includes exhaust hoods
and gravity dampers located in the
return air section. When the
pressure of the building increase,
the gravity dampers open and
relieve air to the outside.
If the return air duct pressure drop
is higher than the building
overpressure, the gravity dampers
will not open.
If the return air duct pressure drop
is lower than the building
overpressure, the gravity dampers
will open and relieve air outside of
the building.

Operation
RT-SVX20A-E448
Operation with a
conventional thermostat
The ReliaTel module has
conventional thermostat
connections as well as Zone Sensor
Module connections. When a
conventional thermostat is
controlling the unit, operation
differs as follows:
Supply Air Tempering feature is
not available. If outdoor air is
being introduced through the
equipment, discharge air
temperature may be cold when
not actively heating.
Proportional Integral (PI) control
is not available.
Zone Sensor Diagnostics are
only available on the RTRM
module on the J6 terminals,
instead of at the Zone Sensor in
the space.
Intelligent Fall-Back is not
available. If a failure occurs in
the device controlling the
equipment, operation will cease.
Heat Pump Smart Recovery and
Smart Staging is not available.
Heat Pump operation becomes
more costly unless the generic
control being applied can
accomplish this.
Remote Sensing Capabilities are
not available on most
mechanical thermostats.
Space Temperature Averaging
capabilities are not available on
most mechanical thermostats.
27½ to 50 VAV - Conventional
thermostat input terminals are
inactive.
Built in Night Set Back and
Unoccupied Functions function
differently with a conventional
mechanical thermostat.
A built-in algorithm which allows
for automatic reset of the
discharge air temperature while
economizing is not available.
The terminal strip for attaching the
thermostat wires is located on the
RTRM module in the control
compartment.
When the unit is operating from a
conventional thermostat or other
binary input, the economizer
setpoint feature, relative to the
cooling and heating setpoints, is
lost. The economizer control is
based strictly on a signal from the
thermostat, but still maintains
mixed air temperature control of
53°±3°F when in the economizer
mode. The economizer enable and
disable function is still determined
by the outside air sensor through
the RTRM.
If a single-stage thermostat is used,
only the economizer (if enabled) or
the compressor (if economizer is
disabled) will operate on a call for
cooling. A twostage thermostat is
required to achieve economizer
operation and compressor
operation at the same time.
With economizer enabled, a Y1 call
for 1st stage cooling will be the
economizer. The damper will
modulate between minimum
position and 100% to maintain
mixed air temperature at 53°±3°. At
50°F the damper will be at
minimum position. If the
economizer is enabled, a Y2 call for
2nd stage cooling will start the first
compressor if required. If the
economizer is disabled, 1st stage
(Y1) will be the first compressor. If
the unit has two compressors, a call
for 2nd stage cooling (Y2) will start
the second compressor. When using
a conventional thermostat, or other
binary input, the ReliaTel controls
will only allow two stages of
cooling.
Figure 30 - Terminal strip
Customers occasionally require
operation with a conventional
thermostat rather than a zone
sensor. In some cases there is a
preference for a specific thermostat
model, and in others there is
reluctance to adopt newer
technology that may not be as well
understood as conventional
thermostats. In addition, non-Trane
Building Controllers typically
provide an interface to HVAC
equipment based on a conventional
thermostat interface. Units applied
with this type of controller need to
accept conventional thermostat
inputs.

Logic is also provided to cause
appropriate unit functions when
inappropriate thermostat signals are
provided. Simultaneous calls for
heating and cooling will be ignored,
and the fan will be turned on with a
call for heating or cooling even if
the fan request is not detected.
If the thermostat is immediately
changed from a heating to a cooling
call, or vice versa, there will be a
five minute delay before the new
call will initiate.
Thermostat signals are as follows:
R 24VAC power to thermostat
Y1 Call for compressor 1 or first

Y2 Call for compressor 2 or 2nd
stage cooling
G Call for supply fan
W1 Call for heat 1

Conventional thermostat signals
represent direct calls for unit
functions. In their simplest
applications, thermostat contacts
directly control contactors or other
load switching devices. This function
provides inputs for the thermostat
signals and processing to enhance
reliability and performance.
Compressor protection and
reliability enhancement functions
(HPC, LPC, Minimum On/Off timers,
etc.). All operate the same whether
applied with zone sensors or a
conventional thermostat.
Operation
RT-SVX20A-E450
Unoccupied mode
If the thermostat being used is
programmable, it will have its own
strategy for unoccupied mode and
will control the unit directly. If a
mechanical thermostat is being
used, a field applied time clock with
relay contacts connected to J6-11
and J6-12 can initiate an
unoccupied mode as follows:
Contacts open: Normal occupied
operation.
Contacts closed: Unoccupied
operation as follows - Fan in
auto mode regardless of fan
switch position. Economizer
closes except while economizing
regardless of minimum position
setting.
Cooling/Economizer Operation
If unit does not have an economizer,
the Cool/Econ Stage 1 and Stage 2
will call directly for mechanical
cooling (compressor) stages. If the
unit has an economizer, the
Cool/Econ stages will function as
shown in Table 46.
Table 46 - Cooling/Economizer Operation with Thermostat
Notes:
40 to 50 ton CV only
This unit has 3 stages of cooling if using a zone sensor. If using a conventional thermostat it has 2 stages as
follows:

Setting the economizer or
0-50% motorized hood
(option)
The ECA board is mounted on the
damper actuator. To access the ECA
board on economizers:
Remove the filter access panel of
the unit.
The electrical power must be
disconnected to set the
minimum position and check the
economizer.
Disconnect the power supply,
put the thermostat fan selector
to "ON" and the "HEAT/COOL"
selector to "OFF". This puts the
damper in the minimum
ventilation position.
To set the required minimum
ventilation air position, turn the
dial on the ECA clockwise to
increase ventilation, or anti-
clockwise to decrease ventilation.
The damper will open at this
setting whenever the fan circuit
is powered up (see Figure 25).
When the arrow on the dial's
adjustment screw is pointing to
8 o'clock, the minimum position
is roughly 0%. When the dial is
pointing to 12 o'clock it is
roughly 25%, and when the dial
is pointing to 4 o'clock it is
roughly 50% (see figure 25).
Operation
51RT-SVX20A-E4
To check the damper is functioning
correctly, the ECA is equipped with
an indicator light in the middle of
the board. This light operates as in
Table 42.
Table 47 - ECA board LED
While setting the minimum position
the damper may move towards the
new setting in several small steps.
Once the damper has remained in
the same position for 10 to 15
seconds it can be assumed it is in
the new position.

WARNING! If any operating checks
must be performed with the unit
operating, it is the technician's
responsibility to recognize any
possible hazards and proceed in a
safe manner. Failure to do so could
result in severe personal injury or
death due to electrical shock or
contact with moving parts.
Power-up initialization
CAUTION! Before proceeding with
any test procedure or operation,
make sure that crankcase heaters
have been energized for at least
8 hours.
Units equipped with Scroll
compressors do not have crankcase
heaters.
Note: Upon power initialization, the
RTRM performs self-diagnostic
checks to insure that all internal
controls are functional. It also
checks the configuration parameters
against the components connected
to the system. The Liteport LED
located on the RTRM module is
turned "On" within 1 second of
power-up if internal operation is
okay.
Test mode procedure at the
ReliaTel™ control board
Operating the unit from the roof
using the test mode at the
ReliaTel™ control board.
CAUTION! Before proceeding with
the following test procedures, make
sure that thermostat or zone sensor
is off.
CAUTION! Use one of the following
"Test" procedures to bypass some
time delays and to start the unit at
the control panel.
Each step of unit operation can be
activated individually by
temporarily shorting across the
"Test" terminals for two to three
seconds. The Liteport LED located
on the RTRM module will blink
when the test mode has been
initiated. The unit can be left in any
"Test" step for up to one hour
before it will automatically
terminate, or it can be terminated
by opening the main power
disconnect switch. Once the test
mode has been terminated, the
Liteport LED will glow continuously
and the unit will revert to the
"System" control.
Operation
53RT-SVX20A-E4
Test modes
There are 2 methods in which the
"Test" mode can be cycled with the
test button:
1. Step Test Mode
This method initiates the different
components of the unit, one at a
time, by temporarily shorting across
the two test terminals for two to
three seconds. For the initial startup
of the unit, this method allows the
technician to cycle a component
"On" and have up to 1 hour to
complete the check.
2. Auto Test Mode
This method is not recommended
for start-up due to the short timing
between individual component
steps. This method initiates the
different components of the unit,
one at a time, when a jumper is
installed across the test terminals.
The unit will start the first test step
and change to the next step every
30 seconds. At the end of the test
mode, control of the unit will
automatically revert to the applied
"System" control method.
For unit test steps and test modes,
values to cycle the various
components, refer to Tables 48
and 49.

verify the operation of this unit from
the roof, use the "Test procedure"
section in this manual. Check the
suction and discharge pressures.
Note: Always route refrigerant
hoses through the port hole
provided and ensure that the
compressor access panel is in place.
Cooling shutdown
To exit the test mode, disconnect
unit power for 3-5 seconds and
reapply. When running the unit
using the zone sensor as the
control, position the selector switch
to "OFF".
There may be a delay of up to
3 minutes before compressors shut
down and an additional one minute
before the fan shuts down in this
setting.
Do not de-energize main power
disconnect except when unit is to
be serviced. Power is required to
keep the compressor crankcase
warm and boil off refrigerant in the
oil (except on units with Scroll
compressors).

Operation
RT-SVX20A-E456
ReliaTel™ is a microelectronic
control feature, which provides
operating functions that are
significantly different from
conventional electro-mechanical
units. The master module is the
ReliaTel™ Refrigeration Module
(RTRM).
The RTRM provides compressor
antishort cycle timing functions
through minimum "Off" and "On"
timing to increase reliability,
performance and to maximize unit
efficiency.
Upon power initialization, the RTRM
performs self-diagnostic checks to
insure that all internal controls are
functioning. It checks the
configuration parameters against
the components connected to the
system.
The LED located on the RTRM
module is turned "On" within one
second after power-up if all internal
operations are okay.
Cooling without an
Economizer
When the system switch is set to
the "Cool" position and the zone
temperature rises above the cooling
setpoint controlband, the RTRM
energizes the (K9) relay coil located
on the RTRM. When the K9 relay
contacts close, the compressor
contactor (CC1) coil is energized
provided the low pressure control
(LPC1) and high pressure control
(HPC1) are closed. When the CC1
contacts close, compressor (CPR1)
and the outdoor fan motor (ODM)
start to maintain the zone
temperature to within ± 2 F of the
sensor setpoint at the sensed
location.
If the first stage of cooling can not
satisfy the cooling requirement, the
RTRM energizes the (K10) relay coil
located on the RTRM. When the
(K10) relay contacts close, the
compressor contactor (CC2) coil is
energized provided the low
pressure control (LPC2) and high
pressure control (HPC2) are closed.
When the CC2 contacts close,
compressor (CPR2) starts to
maintain the zone temperature to
within ± 2 F of the sensor setpoint
at the sensed location.
Evaporator Fan Operation
When the fan selection switch is set
to the "Auto" position, the RTRM
energizes the (K6) relay coil
approximately one second after
energizing the compressor
contactor coil (CC1) in the cooling
mode. In heating mode, the RTRM
energizes the (K6) relay coil
approximately 45 seconds after gas
ignition. Closing the K6 contacts on
the RTRM energizes the supply fan
relay (F) coil to start the supply fan
motor (IDM).
The RTRM de-energizes the fan
relay (F) approximately 60 seconds
after the cooling requirement has
be satisfied to enhance unit
efficiency.
When the heating cycle is
terminated, the supply fan relay (F)
coil is de-energized approximately
90 seconds after the heating
requirement.
When the fan selection switch is set
to the "On" position, the RTRM
keeps the supply fan relay coil (F)
energized for continuous fan motor
operation.
When the unit is equipped with the
optional clogged filter switch, wired
between terminals J7-3 and J7-4 on
the ReliaTel™ Options Module
(RTOM), the RTRM produces an
analog output if the clogged filter
switch (CFS) closes for two minutes
after a request for fan operation.
When the system is connected to a
remote panel, the "SERVICE" LED
will be turned on when this failure
occurs.
Operation
57RT-SVX20A-E4
Low Ambient Operation
During low ambient operation,
outside air temperature below 13ºC,
the RTRM will cycle the compressor
and outdoor fan motor "Off" for
approximately three minutes after
every 10 minutes of accumulated
compressor run time. The supply
fan motor (IDM) will continue to
operate during this evaporator
defrost cycle (EDC) and the
compressor and outdoor fan will
return to normal operation once the
defrost cycle has terminated and
the compressor "Off" time delay has
been satisfied.
Cooling with an
Economizer
The economizer is utilized to control
the zone temperature providing the
outside air conditions are suitable.
Outside air is drawn into the unit
through modulating dampers. When
cooling is required and economizing
is possible, the RTRM sends the
cooling request to the unit
economizer actuator (ECA) to open
the economizer damper. The RTRM
tries to cool the zone utilizing the
economizer to slightly below the
zone temperature setpoint. If the
mixed air sensor (MAS) senses that
the mixed air temperature is below
53ºF, the damper modulates toward
the closed position. If the zone
temperature continues to rise above
the zone temperature setpoint
controlband and the economizer
damper is full open, the RTRM
energizes the compressor contactor
(CC1). If the zone temperature
continues to rise above the zone
temperature setpoint controlband
and the economizer damper is fully
open, the RTRM energizes the
compressor contactor (CC2).
The ECA continues to modulate the
economizer damper open/closed to
keep the mixed air temperature that
is calculated by the RTRM.
If economizing is not possible, the
ECA drives the damper to the
minimum position setpoint when
the supply fan relay (F) is energized
and allows mechanical cooling
operation. When the unit is
equipped with the optional fan
failure switch, wired between
terminals J7-5 and J7-6 on the
RTOM, the RTRM will stop all
cooling functions and produce an
analog output if the fan failure
switch (FFS) does not open within
40 seconds after a request for fan
operation. When the system is
connected to a remote panel, the
"SERVICE" LED will flash when this
failure occurs.
Operation
RT-SVX20A-E458
Economizer Set-Up
Adjusting the minimum position
potentiometer located on the unit
economizer Actuator (ECA) sets the
required amount of ventilation air.
Two of the three methods for
determining the suitability of the
outside air can be selected utilizing
the enthalpy potentiometer on the
ECA, as described below:
1. Ambient Temperature -
controlling the economizing
cycle by sensing the outside air
dry bulb temperature. The Table
below lists the selectable dry
bulb values by potentiometer
setting.
2. Reference Enthalpy - controlling
the economizer cycle by sensing
the outdoor air humidity. The
Table below lists the selectable
enthalpy values by
potentiometer setting.
If the outside air enthalpy value
is less than the selected value,
the economizer is allowed to
operate.
3. Comparative Enthalpy - By
utilizing a humidity sensor and a
temperature sensor in both the
return air stream and the
outdoor air stream, the unit
control processor (RTRM) will be
able to establish which
conditions are best suited for
maintaining the zone
temperature, i.e. indoor
conditions or outdoor conditions.
The potentiometer located on
the ECA is non-functional when
both the temperature and
humidity sensors are installed.

Ignition Module
Two Stage (IGN) runs self-check
(including verification that the gas
valve is de-energized). (IGN) checks
the high-limit switches (TC01 &
TC02) for normally closed contacts.
With 115 VAC power supplied to the
ignition module (IGN), the hot
surface ignition probe (IP) is
preheated for approximately
45 seconds. The gas valve (GV) is
energized for approximately
7 seconds for trial for ignition, to
ignite the burner.
Once the burner is ignited, the hot
surface ignition probe (IP) is de-
energized by the ignition module
(IGN) and functions as the flame
sensing device.
If the burner fails to ignite, the
ignition module will make two more
attempts before locking out. The
green LED will indicate a lock out by
two fast flashes. An ignition lockout
can be reset by:
1. Opening for 3 seconds and
closing the main power
disconnect switch
2. By switching the "Mode" switch
on the zone sensor to "OFF" and
then to the desired position
3. Allowing the ignition control
module to reset automatically
after one hour.
Operation
59RT-SVX20A-E4
Refer to the ignition control module
diagnostics section for the LED
diagnostic definitions.
When the fan selection switch is set
to the "Auto" position, the RTRM
energizes the supply fan relay (F)
coil approximately 30 second after
initiating the heating cycle to start
the supply fan motor (IDM).
The automatic reset high limit
(TCO1), located in the bottom right
corner of the burner compartment,
protects against abnormally high
leaving air temperatures.
The automatic reset fan fail limit
(TCO2), located in the upper middle
section of the supply fan board,
protects against abnormally high
heat buildup which could occur
because of extended cycling of the
high limit (TCO1) or if the supply
fan motor (IDM) fails to operate.
Should TCO2open, the RTRM will
energize the supply fan relay (F) in
an attempt to start the fan motor.
The RTRM signals that a heat failure
has occurred by flashing the "Heat"
LED on the zone sensor.
There is a Green LED located in the
Ignition Control Module. The table
below lists the diagnostics and the
status of the LED during the various
operating states.
Final installation checklist
Is the condenser fan and indoor
blower operating correctly, i.e.:
correct rotation and without
undue noise?
Are the compressors operating
correctly and has the system
charge been checked?
Has the gas module been
installed as per the procedure in
this manual?
Have the voltage and running
currents been checked to
determine if they are with in
limits?
Have the air discharge grilles
been adjusted to balance the
system?
Has the ductwork been checked
for air leaks and any
condensation?
Has the heating air temperature
rise been checked?
Has the indoor airflow been
checked and adjusted if
necessary?
Has the unit been checked for
tubing and sheet metal rattles
orany unusual noises?

recommends that a qualified service
technician check the entire system
at least once each year, or more
frequently if conditions warrant it.
End user routine
maintenance
Some of the periodic maintenance
functions for the unit can be
undertaken by the end user. This
includes replacing (disposable) or
cleaning (permanent) air filters,
cleaning unit cabinet, cleaning the
condenser coil, and carrying out a
general unit inspection on a regular
basis.
WARNING! Disconnect the power
supply before removing access
panels to service the unit. Failure to
disconnect power before attempting
any servicing can result in severe
injury or death.
Air filters
It is very important for the central
duct system air filters to be kept
clean.
These should be inspected at least
once a month when the system is in
constant operation (in new
buildings, the filters should be
checked every week for the first four
weeks). If disposable-type filters are
used, they should only be replaced
with ones of the same type and
size.

Note: Do not attempt to clean
disposable filters. Permanent filters
can be cleaned by washing with a
mild detergent and water. Ensure
that the filters are thoroughly dry
before reinstalling them in the unit
(or duct system).
Note: Replace permanent filters
annually if washing fails to clean
them, or they show signs of
deterioration. Be sure to use the
same type and size as were
originally installed.
Condenser coil
Unfiltered air circulates through the
unit's condenser coil and can cause
the coil's surface to become
clogged with dust, dirt, etc. To clean
the coil, brush the coil surface in the
direction of the fins with a soft
bristled brush.
Keep all vegetation away from the
condenser coil area.
Hot water coil (option)
Stop the unit. Do not disconnect the
main supply to the unit. This will
permit the anti-frost protection to
continue to operate, and avoid
water to freeze-up in the coil.

Troubleshooting
The RTRM has the ability to provide
the service personnel with some
unit diagnostics and system status
information. Before turning the
main power disconnect switch "Off",
follow the steps below to check the
ReliaTel™
Refrigeration Module (RTRM). All
diagnostics & system status
information stored in the RTRM will
be lost when the main power is
turned "Off".
1. Verify that the Liteport LED on
the RTRM is burning
continuously. If the LED is lit, go
to Step 3.
2. If the LED is not lit, verify that
24 VAC is present between J1-1
and J1-2. If 24 VAC is present,
proceed to Step 3. If 24 VAC is
not present, check the unit main
power supply, check transformer
(TNS1). Proceed to Step 3 if
necessary.
3. Utilizing "Method 1" or
"Method 2" in the system status
diagnostic section, check the
following: System status,
Heating status, Cooling status. If
a System failure is indicated,
proceed to Step 4. If no failures
are indicated, proceed to Step 5.
4. If a System failure is indicated,
recheck Steps 1 and 2. If the LED
is not lit in Step 1, and 24 VAC is
present in Step 2, the RTRM has
failed. Replace the RTRM.
5. If no failures are indicated, use
one of the TEST mode
procedures described in the unit
"Start-Up" section to start the
unit. This procedure will allow
you to check all of the RTRM
outputs, and all of the external
controls (relays, contactors, etc.)
that the RTRM outputs energize,
for each respective mode.
Proceed to Step 6.
6. Step the system through all of
the available modes, and verify
operation of all outputs, controls,
and modes. If a problem in
operation is noted in any mode,
you may leave the system in that
mode for up to one hour while
troubleshooting. Refer to the
sequence of operations for each
mode, to assist in verifying
proper operation. Make the
necessary repairs and proceed to
Steps 7 and 8.
7. If no abnormal operating
conditions appear in the test
mode, exit the test mode by
turning the power "Off" at the
main power disconnect switch.
8. Refer to the individual
component test procedures if
other microelectronic
components are suspect.
System Status Checkout Procedure
"System Status" is checked by using
one of the following two methods:
Method 1
If the Zone Sensor Module (ZSM) is
equipped with a remote panel with
LED status indication, you can check
the unit within the space. If the ZSM
does not have LED's, use Method 2.
THS/P03 have the remote panel
indication feature. The LED
descriptions are listed below:
LED 1 (System) "On" during normal
operation. "Off" if a system failure
occurs or the LED fails. "Flashing"
indicates test mode.
LED 2 (Heat) "On" when the heat
cycle is operating. "Off" when the
heat cycle terminates or the LED
fails. "Flashing" indicates a heating
failure.
LED 3 (Cool) "On" when the cooling
cycle is operating. "Off" when the
cooling cycle terminates or the LED
fails. "Flashing" indicates a cooling
failure.
LED 4 (Service) "On" indicates a
clogged filter. "Off" during normal
operation. "Flashing" indicates an
supply fan failure.
Maintenance
63RT-SVX20A-E4
Below is the complete listing of
failure indication causes:
System failure
Check the voltage between
terminals 6 and 9 on J6, it should
read approximately 32 VDC. If no
voltage is present, a system failure
has occurred. Refer to Step 4 in the
previous section for the
recommended troubleshooting
procedure.

coils, and any of the controls
below that apply to the unit
(HPC1, HPC2).
4. LPC1 has opened during the
3 minute minimum "on time"
during 4 consecutive compressor
starts, check LPC1 or LPC2 by
testing voltage between the J1-8
& J3-2 terminals on the RTRM
and ground. If 24 VAC is present,
the LPC's has not tripped. If no
voltage is present, LPC's has
tripped.
Service Failure
1. If the supply fan proving switch
has closed, the unit will not
operate (when connected to
RTOM), check the fan motor,
belts, and proving switch.
2. Clogged filter switch has closed,
check the filters.
Simultaneous Heat and Cool Failure
1. Emergency Stop is activated
Method 2
The second method for determining
system status is done by checking
voltage readings at the RTRM (J6).

To use LED's for quick status
information at the unit, purchase a
ZSM and connect wires with
alligator clamps to terminals 6
through 10.
Connect each respective terminal
wire (6 through 10) from the Zone
Sensor to the unit J6 terminals 6
through 10.
Note: If the system is equipped
with a programmable zone sensor
THS03, the LED indicators will not
function while the ZSM is
connected.
Resetting Cooling and Ignition
Lockouts
Cooling Failures and Ignition
Lockouts are reset in an identical
manner. Method 1 explains
resetting the system from the space,
Method 2 explains resetting the
system at the unit.
Note: Before resetting Cooling
Failures and Ignition Lockouts,
check the Failure Status Diagnostics
by the methods previously
explained.
Diagnostics will be lost when the
power to the unit is disconnected.
Method 1
To reset the system from the zone,
turn the "Mode" selection switch at
the zone sensor to the "Off"
position.
After approximately 30 seconds,
turn the "Mode" selection switch to
the desired mode, i.e. Heat, Cool or
Auto.
Method 2
To reset the system at the unit,
cycle the unit power by turning the
disconnect switch "Off" and then
"On".
Lockouts can be cleared through the
building management system. Refer
to the building management system
instructions for more information.
Zone Temperature Sensor (ZTS)
Service Indicator
The ZSM SERVICE LED is a generic
indicator that will signal the closing
of a Normally Open switch at any
time, providing the Indoor Motor
(IDM) is operating. This indicator is
usually used to indicate a clogged
filter, or an air side fan failure.
The RTRM will ignore the closing of
this Normally Open switch for 2 (±1)
minutes. This helps prevent
nuisance SERVICE LED indications.
The exception is the LED will flash
40 seconds after the fan is turned
"On" if the Fan Proving Switch is not
made.
Clogged Filter Switch
This LED will remain lit the entire
time that the Normally Open switch
is closed. The LED will be turned off
immediately after resetting the
switch (to the Normally Open
position), or any time that the IDM
is turned "Off".
If the switch remains closed, and
the IDM is turned "On", the SERVICE
LED will be turned "On" again after
the 2 (±1) minute ignore delay.
This LED being turned "On", will
have no other affect on unit
operation. It is an indicator only.
Fan Failure Switch
When the "Fan Failure" switch is
wired to the RTOM, the LED will
remain flashing the entire time the
fan proving switch is closed,
indicating a fan failure, and it will
shut the unit operations down.
