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
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.
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.
