Heating circuit controller Deltatherm® HT

The DeltaTherm® HT is a compact and user-friendly solution for simple heating systems and offers weather-compensated control with room influence or demand-based room control with 1 room temperature sensor. If a central outdoor sensor unit is used, several controllers can use the outdoor temperature value – this requires the installation of only 1 outdoor temperature sensor. Additionally, there’s a choice of 5 different operating modes and a night correction.
