These devices automatically switch off the current in the controlled circuit as the pre-set temperature is reached, and switch it on again as the temperature falls below the set threshold value. The temperature of the controlled medium is thus maintained within a narrow zone.
Working temperature range: 0 – 355 °C
Areas of application:
– water heaters, hot water storage tanks
– washing machines
– electric cooking hearths and domestic baking ovens
Trouble-free operation is conditioned by proper heat transfer between the controller’s sensor and the controlled medium.
