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

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.

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 self­supporting 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 flame to check for gas leaks.
Required gas pressure at the unit inlet connection are given in Table 50.
Note:To operate with propane gas, the burner is fitted with a pressure limiter (supplied by Trane)

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
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 cross­sectional 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.

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.

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.

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.

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:

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.

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 anti­clockwise 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.

Duct network is correctly sized according to the unit configuration, insulated, and water-tight
Condensate drainage line is correctly sized, equipped with a trap, and sloped
Filters are in position, of correct size and quantity and clean
Wiring is correctly sized and connected in accordance with wiring diagrams
Power supply lines are protected by recommended fuses and correctly earthed
Thermostat is correctly wired and positioned
Unit is checked for refrigerant charge and leaks
Indoor and outdoor fans rotate freely and are fixed on shafts
Supply fan rotation speed is set
Access panels and doors are replaced to prevent air entering and risks of injury
Checking of the gas heating section, in accordance with above procedure
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.

Starting the unit in cooling mode
Before start-up, ensure that all power cables are tightened.
Verify that the unit airflow rate is adjusted according to the information provided in the "Supply fan adjustment" section of this manual.
To start the unit in cooling mode:
• Place the zone sensor system switch in the "COOL" position.
• Position the cooling setpoint approximately 10° below room temperature and place the fan switch in the "AUTO" or "ON" position.
• Turn on unit main power supply.
The condenser fan motor, compressor and supply fan motor should operate automatically.
There will be a delay of up to 5 minutes before the unit starts in cooling mode.
Operating pressures
After the unit has operated in cooling mode for a short period of time, install pressure gauges on the gauge ports of the discharge and suction line valves.
Note:To bypass time delays and 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).
Final installation checklist
• Are all power cables tightened?
Check torque of power cables contact !
• 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 been checked for leaks?
• Have the voltage and running currents been checked to determine if they are within 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 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 or any unusual noises?
• Are all covers and panels in place and properly fastened?
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 de­energized 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 (TCO
2), 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 TCO
2 open, 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.

Maintenance
RT-SVX20A-E460
To keep the unit operating safely and efficiently, the manufacturer 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.

Maintenance
61RT-SVX20A-E4
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.
Service technician maintenance
Before the cooling season, your service technician may examine the following areas of your unit:
• Filters, for cleaning or replacement
• Motors and drives system components
• Economizer gaskets, for replacement if necessary
• Condenser coils, for cleaning
• Safety controls, for mechanical cleaning
• Electrical components and wiring, for replacement and tightening of connections as necessary
• Condensate drain, for cleaning
• Unit duct connections, to ensure they are physically sound and sealed to the unit casing
• Unit mounting support, to ensure that it is sound
• The unit, to ensure there is no obvious deterioration
Before the heating season, your service technician may examine the following areas of your unit:
• The unit, to ensure that the condenser coil can receive the required airflow (that the condenser fan grille is not obstructed)
• The control panel wiring, to verify that all electrical connections are tight, and that wire insulation is intact
• Clean burner area, verify the gas heat system operates properly.

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.
Heating Failure
Verify Heat Failure by Ignition Module (IGN) LED indicator:
OFF: No Power or Failure ON: Normal Slow Flash: Normal, Heat Call Fast Flash: Error Code:
1 Flash: Communication Failure 2 Flashes: System Lockout 3 Flashes: Pressure Switch Fail 4 Flashes TC01 or TC02 Open 5 Flashes: Flame w/o Gas Valve 6 Flashes: Flame Rollout Open
Cooling Failure
1. Cooling and heating set point (slide pot) on the zone sensor has failed. Refer to the "Zone Sensor Test Procedure" section.
2. Zone temperature thermistor ZTEMP on ZTS failed. Refer to the "Zone Sensor Test Procedure" section.
3. CC1 or CC2 24 VAC control circuit has opened, check CC1 & CC2 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).
The system indication descriptions and the approximate voltages are listed below.
System Failure
Measure the voltage between terminals J6-9 & J6-6.
Normal Operation = approximately 32 VDC
System Failure = less than 1 VDC, approximately 0.75 VDC
Test Mode = voltage alternates between 32 VDC & 0.75 VDC
Heat Failure
Measure the voltage between terminals J6-7 & J6-6.
Heat Operating = approximately 32 VDC
Heat Off = less than 1 VDC, approximately 0.75 VDC
Heating Failure = voltage alternates between 32 VDC & 0.75 VDC
Cool Failure
Measure the voltage between terminals J6-8 & J6-6.
Cool Operating = approximately 32 VDC
Cool Off = less than 1 VDC, approximately 0.75 VDC
Cooling Failure = voltage alternates between 32 VDC & 0.75 VDC
Maintenance
RT-SVX20A-E464
Service Failure
Measure the voltage between terminals J6-10 & J6-6.
Clogged Filter = Approximately 32 VDC.
Normal = Less than 1 VDC, approximately 0.75 VDC
Fan Failure = voltage alternates between 32 VDC & 0.75 VDC.
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.

To Test Humidity Sensors Return Air Humidity Sensor ECA RAH/RAE Outdoor Humidity Sensor ECA OAH/OAE
To test this circuit, place a DC milliamp meter in series with either of the leads to the humidity sensor. If the reading is 0ma, polarity may be reversed. Reverse + & - and retest. If the reading does not correspond to the table below, check the output voltage from the ECA with the sensor disconnected. It should be approximately 20VDC. If so, and all connections are intact, replace the sensor. If 20VDC is not present, yet the ECA green LED is on, the ECA module has failed.Humidity sensor accuracy : +/-10% RH.
