Technical Information

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.
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.
