Functional Description
Temperature controllers and limiters perform various tasks: They disconnect the system after an adjustable limiting value is exceeded, whereby limiters remain disconnected, while monitors switch back on again when the permissible temperature is reached. They both prevent reconnection if the system is leaking. The set value can be seen from the outside through the sight glass.Safety temperature monitor:If the temperature of the sensor exceeds the set value, the monitor switches off. If the temperature falls below the set value, the monitor switches back on automatically.Safety temperature limiter:If the temperature of the sensor exceeds the set value, the limiter prevents reconnection. Once the temperature has dropped, the safety temperature limiter can be unlocked manually.
