Thermostatic head D-U
With built-in sensor
The thermostatic head D-U is used to control the temperature of individual rooms using, for example, heaters, convectors, and radiators.
Product branding
Features and Benefits
Liquid filled sensor element
For higher closing power, reduced maintenance costs and trouble-free operation.
Temperature limitation
Set maximum and minimum temperatures, helping to reduce running costs.
Reduced size in length and diameter
Applications
Heating systems.
Functions
Temperature control
Frost protection.
Limiting of a setting.
Differential pressure influence
0.3 K
Temperature
Max. sensor temperature: 50°C (122°F)
Nominal temperature range
6 °C - 28 °C, 16 °C - 28 °C
Water temperature influence
0.5 K
Control behavior
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).

0.6 K
Hysteresis
0.6 K
Closing time
17 min
Marking
Heimeier.
