Surface Sensor Thermostatic Heads

Thermostatic heads used for underfloor heating and water heaters. Room temperature is monitored here via a 2 m capillary tube connected to the sensing element.

Location and a proper montage of the surface sensor have an important influence on factually reached temperature.

It’ s recommended to:
- place the sensor directly in the air flow
- fix the sensor to the pipe surface with use of plastic stripes or directly to the water heater through the sealed sensor socket.
