Features & Benefits

    Reduced size in length and diameter

    Liquid-filled thermostat with high pressure power and precision control

    Limiting of a setting

    Technical description

    Applications area:

    Heating systems

    Functions:

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

    Control behavior:

    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:

    0.2 K

    Water temperature influence:

    0.55 K

    Differential pressure influence:

    0.3 K

    Closing time:

    19 min

    Hysteresis:

    0.2 K

    Material:

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