Frost protection thermostats<br />
Purpose:<br />
Frost protection thermostats are designed to prevent water-filled heat<br />
exchangers from freezing.<br />
Method:<br />
The air-side frost temperature must be monitored with a capillary sensor.<br />
Construction Function System<br />
Force/deflection<br />
The capillary frost-protection sensor operates on the principle of vapour<br />
pressure condensation. If the temperature falls below the preset switching<br />
point of 2 °C at any point along any 10 cm length, the vapour pressure in<br />
the sensor system drops, causing the frost alarm to trip.<br />
