Daikin-McQuay 4027033 Control Box Assembly

The Daikin-McQuay 4027033 Control Box Assembly is essential for different HVAC systems especially those with rooftop units. It also controls and co-ordinates the function of the entire unit including the speed of the fan, the functioning of its thermostat, and the interlocking of safety mechanisms. This control box contains a complex set of electronic parts such as sensors, relays and a microprocessor. These elements are active to control the system and modify performance in a real-time to achieve efficiency and comfort goals. The microprocessor takes input data from different types of sensors including temperature sensors and pressure transducers to decide the operating parameters applicable to the system.
