Page 10: Sequence Of Operation
Sequence of Operation. Operation of Refrigeration. 1. When switch is turned on, power is provided to the temperature control, compressor, condenser and evaporator fan motor. And they will run until the box temperature setting is reached. 2. When the box temperature reaches a setting, the compressor and condenser fan motors shut off while evaporator fan motor is working. -
Page 11: Controller Setting
Controller Setting. Danfoss EKC 102D Electronic Controller ( Low Temperature). The EKC 102D is used for temperature control refrigeration appliances and cold room. It contains a temperature control where the signal con be received from one temperature sensor. The sensor is placed in the cold air flow after the evaporator or in the warm air flow just before the evaporator. - Page 12 The buttons; Display The values will be shown with three digits, and with a setting you can determine whether the temperature are to be shown in ℃ or ℉.
