Indoor Fan Motor

The indoor fan is a permanently lubricated, variable
speed DC motor. Indoor fan speed is selected in the
following manner:
When the green thermostat wire is connected to the
high-speed fan (G) terminal:
• DUCT SWITCH UP = HIGH FAN SPEED
• DUCT SWITCH DOWN = MEDIUM FAN SPEED
When the green thermostat wire is connected to the
low-speed fan (G) terminal:
• DUCT SWITCH UP = MEDIUM FAN SPEED
• DUCT SWITCH DOWN = LOW FAN SPEED
The indoor fan and outdoor fan will operate si-
multaneously under normal operating conditions.
To energize the fans, press the FAN button on the
thermostat. When fan ON mode is selected, the fans
will run continuously, independent of the compres-
sor or heaters. Selecting AUTO on the thermostat
will cause the fans to automatically cycle on and off
with the compressor or heaters. The fans will always
run when the compressor or heaters are operat-
ing. They will start before compressor or heater
operation, and will stop after compressor or heater
operation has ended. The fans can also be set to
run continually, regardless of thermostat setting, by
placing the CONST FAN dip switch in the (UP) posi-
tion. (See
