Mark the position of thesubbase mounting holes and drill holes with a 3/16-inchbit. Install supplied anchors and secure base to the wall.Thermostat wire must be 8-conductor (4 or 5 counductorfor communicating thermostats), 20-AWG (minimum)wire. Strip the wires back 1/4-inch (longer strip lengthsmay cause shorts) and insert the thermostat wires intothe connector as shown. Tighten the screws to ensuresecure connections. The thermostat has the same typeconnectors, requiring the same wiring. See instructionsenclosed in the thermostat for detailed installation andoperation information. The W1 terminal on TPCM32U03A*and TPCM32U04A* communicating thermostats may behard wired to provide aux/emergency heat in the eventcommunication is lost between the thermostat and theABC microprocessor.NOTE: Aurora Base Control (ABC) DIP switch SW2-7 isrequired to be in the “OFF” position for the control tooperate with FaultFlash or ComforTalk thermostats. SW2-7in the “ON” position configures the control to operate withtypical thermostats (continuous lockout signal). Theremust be a wire connecting Y2 on the Aurora controllerto 2nd stage compressor on the thermostat for properoperation. SW2-7 DIP switch position is not relevant withcommunicating thermostats.Figure 10: Thermostat Wiring (Y1 Style Signals)CP7P1–RWC 24VAC (Common)R 24VAC (Hot)B- CommunicationW1 (Optional)ABC ControllerThermostat Connection+ A+ CommunicationTPCM32U03A*/TPCM32U04A*Monochrome ThermostatsCP7–RC 24VAC (Common)R 24VAC (Hot)DX- CommunicationABCControllerThermostatConnection+ DX+ CommunicationTPCC32U01*Color TouchscreenThermostatFigure 11: Thermostat Wiring (Communicating Style Signals)AFFINITY SERIES OUTDOOR PACKAGED HEAT PUMP INSTALLATION MANUAL
