These devices automatically switch off the current in the controlled circuit as the temperature is reached, and switch it on again as the tepmerature falls below the set threshold value. The temperature of the controlled medium is thus maintained within a narrow zone.
Working tepmerature range: 0 – 400 °C
Areas of application:

– gas-powered heaters under electric control
– electric heating devices
– hot water storage tanks

Suitable for controlling two different temperatures!
Trouble-free operation is conditioned by proper heat transfer between the controller’s
sensor and the controlled medium.
