Description
Bosch HVAC 8733933939 Diagnostic Control Board is an electronic controller that is used to control the monitoring of the system and coordination of the operation of heat pump equipment. It operates by using integrated circuitry which interprets signals sent by temperature sensors, pressure switches and safety parts and uses this information to operate compressors, fan motors and protective operates when used in HVAC systems. The board is mounted within the equipment control compartment into which wiring harnesses are connected to the designated terminals and power connections are connected to the control circuit. The continuous signal processing allows diagnostics of the system, observation of the operating conditions, and control of the connected elements.
