Description
The Bosch HVAC 8733953202 Indoor Unit Main Control Board is an electronic component that coordinates the operations of a unit in the HVAC systems, such as the fan operation, sensor input processing, and mode selection. It reads the signals of thermostats and sensors, controls communication between parts, and activates outputs to blowers, valves, and circuits. Fitted either in the air handler or indoor cabinet of compatible residential and light commercial systems, this control board acts as the central logic point that coordinates and provides the correct sequence of operation of heating, cooling, and airflow operations.
