NOTE:
Constant torque motor speed changes
All constant torque motors have 5 speed tabs. Speed tab 1 is for continuous fan. Speed tab 2 (low static) and Speed tab 3 (high static) are for lower tonnage. Speed tab 4 (low static) and Speed tab 5 (high static) are for higher tonnage.
Constant torque air handlers are always shipped from factory at speed tab 5, except for -4824, which is set at speed tab 3.
The low static Speed tab 2 (lower tonnage) and 4 (higher tonnage) are used for external static below 0.5" WC. The high static Speed tab 3 (lower tonnage) and 5 (higher tonnage) are used for external static exceeding 0.5" WC. Move the blue wire to the appropriate
speed tab as required by the application needs.
The airflow for continuous fan (Speed tab 1) is always set at 50% of the Speed tab 4.
The above airflow table lists the airflow information for air handlers without heater and air handler with maximum heater allowed for each model.
The following formula can be used to calculate the approximate airflow, if a smaller (N kw) than the maximum heater kit is installed. Approximate Airflow = Airflow without heater - (Airflow without heater - Airflow with maximum heater) X (N kw/maximum heater kw)
