Refrigeration mode is the normal operating mode of the MR5 Controller. The system cycles the compressor on and off, and operates the evaporator fans according to the setup selections to maintain the setpoint temperature in the refrigerated space. While in refrigeration mode, the Fan icon indicates the evaporator fan relay status and the defrost relay and Defrost icon remain off. The LCD UI displays the HOME screen, which shows the system name, date, time, space temperature, and setpoint.
