Electromechanical thermostat 077B is used to control the temperature in refrigerators, upright and chest freezers, liquid coolers, bottle coolers and small commercial refrigeration appliances. The thermostat can be used as an evaporator thermostat or a room thermostat. The thermostats are available with normal function, fixed cut-in and cut-out temperature, constant or variable cut-in temperature for automatic defrost, and with a push button for semi-automatic defrost. All thermostats have NC (Normally closed) main contacts; i.e. they cut out the compressor current circuit on decreasing temperature.
077B thermostats are available as a standard thermostat range, as a service kit range and as customer specified versions adapted to specific appliances. Service kit thermostats are created with specifications and accessories that allow universal application in the aftermarket, for thermostat servicing on all types of refrigeration and freezing appliances.
