Goodman Mfg IO-431, ASPF Air Handlers operating instructions Aspf Thermostat Connections

ASPF Thermostat Connections

The following composite wiring diagrams detail various con- figurations in which the ASPF air handlers can be used. Ex- amples include single-stage cooling and heat pump with single or two-stage electric heating. All these configurations can be applied with convenient connections to outdoor thermo- stat applications.

The following sections will be detailed:

•Single-Stage Cooling

•Heat Pump

IMPORTANT: WHEN MATCHING THE ASPF AIR HANDLERS TO A SINGLE SPEED COOLING OR HEAT PUMP UNIT, REMEMBER TO CONNECT “Y” FROM THE THERMOSTAT TO THE “Y2” ON THE LOW VOLTAGE TERMINAL BOARD.

An equivalent thermostat can be used in place of the Goodman thermostat part number.

Each diagram details the connections between room ther- mostat and ASPF air handlers, and the connections between the ASPF air handlers and the Condensing Unit (or Heat Pump) with optional connections to Outdoor Thermostats. For each configuration, refer to the explanation of the proper jumper(s) to remove for the corresponding blower speed that will result in the programmed EEM™ motor.

HIGH VOLTAGE! DISCONNECT ALL POWER BEFORE SERVICING. WARNING MULTIPLE POWER SOURCES MAY BE PRESENT. FAILURE TO DO SO MAY CAUSE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
