BLOWER MOTOR SPEED TAP INFORMATION
The constant torque motor is designed with 5 speed taps. The speed
taps are designed to be used as shown below:
Tap 5 is used for HIGH SPEED Cooling operation.
Tap 4 is used for MED-HIGH SPEED Cooling or Heating operation.
Tap 3 is used for MEDIUM SPEED Cooling or Heating operation.
Tap 2 is used for MED-LOW SPEED Heating operation.
Tap 1 is used for LOW SPEED Constant Circulation operation
ONLY. This speed tap circulates around 200 CFM and is energized
by the “G” thermostat terminal. Tap 1 does not circulate enough air
to support the heating or cooling operation. If used for cooling the
evaporator coil will freeze up. If used for heating the limits will open
very quickly.
