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.
Features & 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
