CONSTANT TORQUE (EEM) MOTORS
ACNF25 and ACNF31 models utilize constant torque (EEM) motors.
These motors come with a separate control box which is mounted
on the side of the unit as shown in Figure 8. The harness from the
motor is inserted into the control box which has another harness
leading into the control panel of the unit.

The high voltage wiring is the same as the other ACNF models.
The low voltage wiring connections for the ACNF25 and ACNF31
models are shown in Figure 9. The wire from the motor, T2
(purple,) T3 (pink) or T4 (yellow), connects to “Y” from the
thermostat/condenser depending on the application. The rest of
the connections are similar to the other ACNF models.

MAINTENANCE
Room Thermostat
The room thermostat controls the operation of your heating and/
or cooling unit. It senses the indoor temperature and signals the
equipment to start or stop maintaining the temperature you have
selected for your comfort. The room thermostat should be in a
central, draft free inside wall location for best operation. Do not place
any heat producing apparatus such as lights, radio, etc., near the
thermostat as this will cause erratic operation of the comfort system.
