    Technical description

    Applications area:

    Heating systems

    Functions:

    Room temperature control.
    Frost protection.
    Locking of a setting.

    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:

    0 °C - 28 °C
    6 °C - 28 °C

    Temperature:

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

    Specific extension:

    0.22 mm/K,
    Valve stroke limiter

    Control accuracy, CA value:

    0.6 K

    Water temperature influence:

    0.7 K

    Differential pressure influence:

    0.2 K

    Closing time:

    16 min

    Hysteresis:

    0.7 K

    Material:

    ABS, PA6.6GF30, brass, steel,
    Liquid-filled thermostat.

    Marking:

    IMI Heimeier and KEYMARK symbol.
    Setting scale with temperature values or I-IIIII.
    Symbols for basic setting and nighttime reduction.

    Standard:

    KEYMARK certified and tested according to EN 215. See also leaflet "Thermostatic Heads - General".

    Surface closed on all sides. Particularly suitable for hygienically demanding areas in health care or food / industrial sector.

    Connection:

    Designed to be mounted on all HEIMEIER thermostatic valve bodies and radiators with integrated valves which have an M30x1.5 thermostatic insert.
