    Technical description

    Applications area:

    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).

    Nominal temperature range:

    6 °C - 28 °C

    Temperature:

    Max. sensor temperature: 50°C (122°F)

    Specific extension:

    0.22 mm/K,
    Valve stroke limiter

    Setting numbers 1-5.
    Symbols for basic setting and nighttime reduction.
    Brief data including the most important settings.
    Setting indicators on the face of the head and markings designed for the visually impaired.
    Rotation direction indicator.

    Connection:

    The thermostatic head VK has been designed to be mounted on radiators with integrated valves. The clamp connection with locking ring enables a direct connection to thermostatic inserts which do not have an M 30 x 1.5 connecting thread.
    The thermostatic head VK can be mounted in several different positions, each at 90°.
