The EKC 202A is a temperature controller designed for refrigeration applications. It is capable of receiving signals from one temperature sensor, which can be placed either in the cold air flow after the evaporator or in the warm air flow just before the evaporator. The controller manages defrosting processes, which can be either natural or electric, and can restart cooling based on time or temperature. It also supports the use of a defrost sensor for direct measurement of defrost temperature.
