NOTE:
Constant torque speed changes
All constant torque motors have 5 speed taps. Speed tap 1 is for continuous fan. Speed tap 2 (low static) and speed tap 3 (high static) are for lower tonnage. Speed
tap 4 (low static) and speed tap 5 (high static) are for higher tonnage.
Constant torque air handlers are always shipped from factory at speed tap 5. To change to 1.5-ton or 2.5 ton airflow, move the blue wire to speed tap 2 or 3 on the
constant torque motor.
The low static speed tap 2 (lower tonnage) and 4 (higher tonnage) are used for external static below 0.5" WC. The high static speed tap 3 (lower tonnage) and 5
(higher tonnage) are used for external static exceeding 0.5" WC. Move the blue wire to the appropriate speed tap as required by the application needs.
• The airflow for continuous fan (speed tap 1) is always set at 50% of the speed tap 4.
• The above airflow table lists the airflow information for air handlers with maximum heater allowed for each model.
