With built-in sensor and remote sensor

The thermostatic heads K are used to control the temperature of individual rooms using, for example, heaters, convectors, and radiators. The thermostatic head K range not only provides high-precision control it also is designed for exceptional ease of use. The models with remote sensor enables the installation of the thermostatic head covered by curtains, radiator facings, or other obstructions, or mounted vertically or in tight niches.

Key features

Liquid-filled thermostat with high pressure power and precision control

With 2 clips for marking, limiting or blocking

Symbols for basic setting and nighttime set back

Brief data including the most important settings

Rotation direction indicator

Markings designed for the visually impaired

Technical description

Application:

Heating systems

Functions:

Room temperature control.
Frost protection.
Markings indicate upper and lower temperature range; two energy saving clips can be used to limit settings.
Temperature range is limited on both ends and can be blocked using covered stop clips.

Control behavior:

Proportional controller without auxilliary energy. Liquid-filled thermostat. High pressure power, lowest hysteresis, optimal closing time.
Stable control behavior even in the case of small calculated p-band variation (<1K).
