Function
The product protects the boiler against overheating; it is operated without
supply voltage. The heat sensors are connected to a thermally controlled
valve (stroke valve) by means of a capillary tube.
If the boiler temperature increases, the capillary liquid in the heat sensor
expands and applies pressure to the valve. As soon as the boiler temperature
exceeds 99 °C, the valve opens and cold water flows into the heat exchanger.
The cold water reduces the boiler temperature. When the boiler temperature
has dropped below the maximum temperature, the valve closes due to the
reduced volume of the capillary liquid.
