OVERVIEW:
The ICM6501 air handler control board operates with hot water heating systems to control the water pump, valve, and blower while monitoring safeties including the freeze protection switch and pressure switch. When the thermostat calls for heat, the control will energize the Water Pump, Valve and Boiler. The blower will energize at the selected speed after 90 seconds to allow the coil to preheat.
