    Technical description

    Application:

    Heating and cooling systems.
    The thermostatic heads 6402-00/6402-09/6412/6602/6662 can be used in conjunction with a heat conducting base as a contact sensor or with an immersion sleeve as an immersion sensor.

    Thermostatic head 6672 as an immersion sensor without immersion sleeve. Sealed to the capillary tube via clamping joints.

    Functions:

    Medium temperature control with thermostatic valve bodies and three-way valves.
    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.

    Nominal temperature range:

    The setting range is
    10° C to 40° C,
    20° C to 50° C,
    20° C to 70° C,
    40° C to 70° C or
    60° C to 90° C.

    Temperature:

    Maximum sensor temperature
    50° C with thermostatic head 6412,
    60° C with thermostatic head 6402,
    80° C with thermostatic head 6602,
    90° C with thermostatic head 6672 and
    100° C with thermostatic head 6662.

    Specific extension:

    6402 / 6602 / 6412 / 6662:
    0.17 mm/K,
    6672:
    0.10 mm/K,
    Valve stroke limiter.

    Material:

    ABS, PA6.6GF30, brass, steel,
    Liquid-filled thermostat.
    Heat conducting base made of aluminum.

    Colour:

    White RAL 9016

    Marking:

    Heimeier.
    Setting numbers.

    Connection:

    Suitable for installation on all HEIMEIER thermostatic valve bodies, three-way reversing valves and three-way mixing valves.
