NOTE:
All (-)H1T air-handlers have 5 speed constant torque motors.
Speed tap 1 is for continuous fan. Speed tap 2 (low static) and speed tap 3 (high static) are for lower tonnage (1.5 or 2.5 tons). Speed tap 4 (low static) and
speed tap 5 (high static) are for higher tonnage (2.0 or 3.0 tons).
(-)H1T air handlers are always shipped from factory at speed tap 5.
The low static speed tap 2 (lower tonnage) and 4 (higher tonnage) are for external static pressures 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 on the motor terminal block 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.
