Description
The Trane MOD3821 Symbio Control Module 700 is a component used to control core operation logic to interpret the input of thermostats, sensors, and safety parts and to coordinate the operation of the compressors, fans, valves, and actuators. It is located in the middle of the residential and commercial control of air handlers, heat pumps, and packaged HVAC systems and is mounted in the electrical compartment of the equipment. These operational phases aid communication to load variations and add efficient heating and cooling.
