NOTICE: It is important to confirm that the operating voltage of the humidifier or EAC being installed matches the output of this control. If not, a field supplied relay or transformer may be necessary to provide the proper control and supply voltage for the accessory being installed. Refer to the manufacturer’s instructions for the humidifier or EAC for additional information.

Thermostat Anticipator Setting:

Proper control of the indoor air temperature can only be achieved if the thermostat is calibrated to the heating and/or cooling cycle. Calibration will help to produce a more constant indoor temperature by adjusting the length of the heating/cooling cycle to fit the application. A vital consideration of this calibration is related to the thermostat heat anticipator.

The proper thermostat heat anticipator setting is 0.2 ampere. To increase the length of the cycle, increase the setting of the heat scale; to decrease the setting of the heat scale.

Anticipators for the cooling operation are generally pre-set by the thermostat manufacturer and require no adjustment.

L. Blower Motor Speed Selection

: Turn off the electrical power to the unit, before attempting to change supply air blower speed wiring.

The heat rise is determined by the blower tap selection on the control board located in the blower compartment. For this ECM system, the ¾ hp motor is equipped with 5 speeds. The unit is set for a temp rise of 600 F. See table 6 for proper blower motor setup:
