Goodman AEPF Supplemental & Opeating Instructions

AEPF
AIR HANDLER
SUPPLEMENTAL & OPEATING INSTRUCTIONS
THIS PRODUCT CONTAINS ELECTRONIC COMPONENTS WHICH REQUIRE A DEFINITE GROUND. PROVISIONS ARE MADE FOR CONNECTION OF THE
GROUND. A DEDICATED GROUND FROM THE MAIN POWER SUPPLY OR AN EARTH GROUND MUST BE PROVIDED.
INSTALLER
These instructions must be used in conjunction with the latest version of IO-286, which is shipped with the unit. It is important
to follow both of these instructions and those in the latest version of IO-286 when installing th AEPF series of air handlers.
THERMOSTAT CONNECTIONS
The following composite wiring diagrams detail various configurations in which the AEPF air handlers can be used. Examples
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 thermostat applications.
The following sections will be detailed:
• Single-Stage Cooling (GMC Thermostat Part #CHT18-60 or equivalent.)
• Heat Pump (GMC Thermostat Part #18-60 or equivalent)
Each diagram details the connections between room thermostat and AEPF air handlers, and the connections between the
AEPF 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 ECM™ motor.
IMPORTANT: WHEN MATCHING THE AEPF AIR HANDLERS TO A SINGLE STAGE COOLING UNIT
OR HEAT PUMP, REMEMBER TO CONNECT THE "Y/Y2" THERMOSTAT CONNECTION ON THE
VARIABLE SPEED BOARD (VSTB) TO THE THERMOSTAT. CONNECTING "Y1" WILL RESULT IN
FIRST STAGE COOLING BLOWER SPEED AND MAY CAUSE THE CONTACTOR TO CHATTER.
An equivalent thermostat can be used in place of the Goodman thermostat part number. The GMC thermostats that listed are
mercury type thermostats.
