COMBINED TEMPERATURE CONTROLLER AND LIMITER WITH POSITIVE SAFETY 1+2 POLES

COMBINED TEMPERATURE CONTROLLER AND LIMITER WITH POSITIVE SAFETY 2+2 POLES OR 3+3 POLES

These safety devices automatically switch off the current in the controlled circuit as the 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. At the control failure, these devices automatically switch off the current in the controlled circuit as the pre-set temperature limit is reached, thus preventing overheating. Once the defection of the temperature regulation was repaired, in voltage-free state, and after re-cooling to room-temperature (25 +/-5°C), the limiter/protective guard can be re-started manually.

Failsafe operation means that in case of mechanical damage or leaking of the filling-fluid, the safety cut-out will perform one last switch and break the electrical circuit.
Working tepmerature range: 0 – 150 °C
Areas of application:
– household heating boilers
– hot-water boilers and hot-water storage tnaks

Trouble-free operation is conditioned by proper heat transfer between the controlled medium and the controller’s and limiter’s sensors.
