WIRING & SWITCHES : TURN OFF THE ELECTRICAL POWER to the furnace before attempting to disconnect blower wiring. Figure 2: BOARD LAYOUT WITH SWITCHES 2 All installations and services must be performed by qualified service personnel. C. Inputs Power supplies Line voltage is applied between the "S1" and "N1" quick connect terminals. 24 VAC Class II Transformer secondary voltage supplied to X and C Limit Switch The 120VAC limit switch is connected to pins P2-1 & 9. Refer to the Heat Mode section for the control operation. Thermostat call for heat "W" 24 VAC thermostat input. A call for heat is recognized when the thermostat connects "W" to "R". This input has an indicator LED that will light when the control receives a call for heat. Refer to the Heat Mode section for the control operation. Thermostat call for cool, "Y" 24 VAC thermostat input. A call for cooling is recognized when the thermostat connects "Y" to "R. This input has an indicator LED that will light when the control receives a call for cooling. . Refer to the Cool Mode section for the control operation. Thermostat call for dehumidification "DEHUM” 24 VAC thermostat input. A call for dehumidification is recognized when the humidistat connects "DEHUM" to "R". This input has an indicator Led that will light when the control receives a call for dehumidification. Refer to the Cool Mode section for the control operation. Thermostat call for fan "G" 24 VAC thermostat input. A call for fan is recognized when the thermostat connects "G" to "R". This input has an indicator LED in that will light when the control receives a call for fan. Refer to the Fan Mode section for the control operation. D. Outputs ECM Control The control controls a multiple speed ECM motor through the 6-pin P3 connector. This connector provides connection for ECM Speed common (Pin 1), Speed output (Pin 2), Blower Enable (Pin 4), Cool Enable (Pin 5) and “R” output (Pin 6). Oil Burner Control The control provides dedicated contacts to operate the T-T input of an oil primary control. Rating shall be class 2 - 24 VAC pilot duty @ 24 VAC (< 200mA). Power The switched 120VAC power from the LIMIT switch passes through the board between Pins 1&2 of connector P2. Compressor contactor The control provides switched 24VAC to operate a compressor contactor. Rating shall be class 2 - 24 VAC pilot duty @ 24 VAC (< 200mA). 3 All installations and services must be performed by qualified service personnel. EAC (electronic air cleaner) The control provides a 120VAC output for an electronic air Cleaner. This output is energized whenever the fan motor is energized (either low, heat or cool speed). Connection is made via male quick connect terminal labeled...
