SEQUENCE OF OPERATION FOR GAM5 AIR HANDLERS GAM5 Sequence of Operation: Abbreviations TDR = Time Delay Relay EVC = Expansion Valve Control EEV = Electronic Expansion Valve YI = Y signal into the EVC from the comfort control YO = Y signal out of the EVC from the comfort control OEM = Original Equipment Manufacturer See unit, electric heat, and field wiring diagrams for additional information. Continuous Fan IMPORTANT: If the indoor air exceeds 60% relative humidity or simply feels uncomfortably humid, it is recommended that the indoor fan only be used in the AUTO mode. 1. R-G contacts close on comfort control sending 24VAC to the G terminal on the fan TDR 2. Low speed contacts close in the TDR and send 24VAC on terminal labeled LOW. 3. Blower motor will now run on low speed. Speed is field selectable. Heat Pump OD (cooling) 1. R-Y contacts close on the comfort control sending 24VAC to Y terminal on TDR and the YI (Y In) terminal on the EVC. 2. R-G contacts also close on the comfort control sending 24VAC to the G terminal on the TDR. (The combination of 24VAC on terminals Y and G on the TDR will close the high speed contacts of the TDR) 3. R-O contacts on the comfort control close sending 24VAC to the O terminal on the EVC. This signals the EVC that the unit is in cooling mode. The EVC will control the EEV to maintain the correct superheat. 4. Normally closed contacts on the EVC will pass 24VAC to the YO terminal providing power to the outdoor unit control circuit 5. The blower motor will now run on high speed. Speed is field selectable. Heat Pump OD (heating) 1. R-Y contacts close on the comfort control sending 24VAC to Y terminal on TDR and the YI (Y In) terminal on the EVC 2. R-G contacts also close on the comfort control sending 24VAC to the G terminal on the TDR. (The combination of 24VAC on terminals Y and G on the TDR will close the high speed contacts of the TDR) The blower motor will now run on high speed. 3. The combination of 24VAC on the Y terminal and zero volts on the O terminal signals the EVC that the unit is in heat-pump heating mode. 4. Normally closed contacts on the EVC will pass 24VAC to the YO terminal providing power to the outdoor unit control circuit 5. The blower motor will now run on high speed Cooling OD 1. R-Y contacts close on the comfort control sending 24VAC to Y terminal on TDR and the YI (Y In) terminal on the EVC 2. R-G contacts also close on the comfort control sending 24VAC to the G terminal on the TDR. (The combination of 24VAC on terminals Y and G on the TDR will close the high speed contacts of the TDR) 3. R-O jumper on the TDR sends 24VAC to the O terminal on the EVC. This signals the EVC that the unit is in cooling mode. The EVC will control the EEV to maintain the correct superheat. 4. Normally closed contacts on the EVC will pass 24VAC to the YO terminal providing power to the outdoor unit control circuit 5. The blower motor will now run on high speed Electric Heating 1. R-W contacts close on the comfort control sending 24VAC to the W terminal on the TDR. 24VAC is also sent to EHC to energize the heat relay. 2. R-G contacts close on the comfort control sending 24VAC to the G terminal on the TDR. (The combination of 24VAC on terminals W and G on the TDR will close the high speed contacts of the TDR) 3. WJ contacts on the TDR close providing an interlock circuit to allow the electric heat relays to operate. The comfort control must be setup to control R-G contacts with a call for electric heat. This closes the interlock circuit and allows the heat relay circuit to be energized. Optional Condensate Switch 1. An optional OEM condensate switch can be installed within the unit. This switch is only available through the National Distribution Center or Global Parts. 2. Switch contacts are normally open and close when water level rises. The closed switch will interrupt current flow to the YO terminal and de-energize the OD unit. 3. Switch is only operational during cooling mode. Condensate overflow is not operational during heating or defrost modes. Standard aftermarket condensate switches cannot be used within the unit but can be installed exterior of the unit. The 3rd party condensate overflow switch must be wired between Y of the thermostat and YI of the EEV control. 15 GAM5-SF-1D
SW1 410 22 1 2 3 Freeze Protection 1. The EVC control has the ability to sense when the coil is beginning to ice. When this event occurs, the contacts to the YO circuit will open and de-energize the OD unit. 2. The indoor blower motor will continue to run to aid in defrosting the coil. After the coil has sufficiently defrosted, the YO contacts will close and cooling operation will begin again. Fan Off Delay 1. The TDR has a dip switch that can enable a 90 second fan off delay anytime a fan call is made from the comfort control. The factory default is ON. To disable the delay, turn power off to the unit, turn the dip switch to the off position and turn power back on to the unit. DIP SWITCH SETTING - Refrigeration Switch Wire Ties Note: Ensure that the system refrigerant is set to match your application, either R-410A or R-22. using the Refrigerant Switch located on the Expansion Valve Control board (EVC) in the Control Pocket. Factory default is R-410A. Note: A power cycle is needed for the EVC to recognize the change. SW1 410 22 GAM5-SF-1D 16

Electronic Expansion Valve Test Note: Close Valve and Open Valve Tests are active in any mode of operation Test Pins: OPEN, CLOSE, TEST (See J4 on EVC Board) Close Valve Test - Touch CLOSE pin to TEST pin. EEV drives closed (5 seconds max) and stays closed for 1.5 minutes (90 seconds). 1) Status LED will be flashing. 2) Gauges should indicate suction pressure dropping. Valve is working. LPCO may trip. Note: The Close Valve Test will exit after 1.5 minutes (90 seconds) and will not reinitiate (requires a break and make to initialize). To clear faults stored in memory, apply a jumper between Close and Test pins for 10 seconds. Open Valve Test - Touch OPEN pin to TEST pin. EEV drives open (5 sec max) and stays open for 30 seconds. 1) Status LED will be flashing. 2) Temperature probe should indicate superheat falling. Valve is working. Note: If jumper is left on pins, the OPEN VALVE TEST will be cleared after 30 seconds and will not reinitiate (requires a break and make to reinitialize). Exit Test Mode - The Open Valve Test or Closed Valve Test can be cancelled by jumping to the opposite mode Test pin. The system will return to normal super heat control. SUBCOOLING ADJUSTMENT The following combinations should be charged to 8 degrees sub-cooling to maintain ratings.

HIGH SUPERHEAT Superheat above 30F at OD unit Start Here Verify that OD condenser coils are clean Verify line set is properly sized for application NO Is subcooling at the outdoor unit between 8-12F? YES Perform temperature sensor check Add refrigerant until subcooling reaches ~10F Is liquid line temperature at the indoor unit within 8F of outdoor liquid line temperature? NO Verify line set size and charge is correct Recheck superheat EEV and coil are working. Replace EVC Check operation YES Perform OPEN VALVE test at EVC. The system is running at maximum capacity and this may be causing the high superheat. Wait until the indoor temperature is less than 80F and check the superheat again. YES YES Does suction pressure go down? Perform CLOSE VALVE test at EVC. YES Does superheat drop below 30F? NO Is indoor temperature >85F? NO NO Ohm coil per Stepper Motor Tables Replace coil NO Is ohm reading correct? YES Replace EEV. Check operation GAM5-SF-1D 22

NOTE: The fan control has a 90 second OFF delay that is factory set on. To turn this feature off, turn dip switch to 0 and cycle power to the unit. Turn comfort to FAN ON mode Constant Torque Motor Troubleshooting This terminal block is located on the motor. Look for labels below on the motor side of the connection. Motor does not run FIGURE 1 Turn off power. Check set screw position and motor bearings. Correct or replace as needed. Check operation NO Does blower wheel turn freely? YES High voltage should always be present. Correct high voltage wiring. NO Is ~230 VAC measured between terminals L & N on the motor? See Figure 1 FIGURE 2 Correct wiring. Check operation YES NO Is 24VAC measured from terminal 8(G) to terminal 9(BL) on the fan control? NO Is ~24 VAC measured between the wire connected to C on the motor and the wire connected to terminal 1 thru 5 on the motor? See Figure 2 YES Replace fan control. Check operation YES Replace motor.
