IMI Heimeier
Compare
​​​​​​​ With built-in sensor The thermostatic head Halo is used to control the temperature of individual rooms using, for example, heaters, convectors, and radiators. The Halo head combines high precision control with slim, cylindrical design.

Surface closed on all sides

Particularly suitable for hygienically demanding areas

Liquid-filled thermostat

for powerful and precise control

Locking of temperature setting by locking slider

Slim, cylindrical design

Technical description

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.
