Product Description

Temperature control with SPST switch and push-button for automatic defrost function.
Terminal 3-4 closes at temperature rise.
Closing with rising temperature and possibility to manually initiate a defrost cycle by pressing the defrost pin.
The so-called semiautomatic defrost function is achieved by pressing the defrost pin (stroke approx.4mm) until latching. By this the main switch is opened and locked until the defrost temperature is reached at the sensing point of the capillary which normally is fixed at the evaporator. After this defrost temperature has been achieved, the pressure pin returns to its OFF position and the normal ON/OFF operation of the temperature
control is reset. Defrost function can be initiated in any position of the dial shaft, if it has been initiated by accident,
the defrost function can be cancelled by turning the dial shaft to OFF position.

Rating at 250V,50HZ

Typical applications

Refrigerators and Freezers.
