RW-ETC-50 Cold Storage Temperature Controller

RW-ETC-50 Cold Storage Temperature Controller

RW-ETC-50 is a temperature controller suitable for M.T. or L.T. ventilating refrigeration applications. Three-channel outputs control compressor, fan and electric heating or thermal defrost; Two sensors measure the storage temperature and evaporator temperature separately , NTC and PTC sensor can be exchanged; Celsius, Fahrenheit can be switch; Display Resolution is optional; Three menus may avoid unreasonably setting of the user; Support many kinds of digital input (door switch, exterior alarm, refrigeration/heating mode switching, pressure switch protection ,etc.), and copy key operation.
