Resol DeltaTherm® HC mini Heating controller

The DeltaTherm^® HC mini offers a compact and user-friendly solution for simple heating systems. It can control a weather-compensated heating circuit and its backup heating demand. Additionally, there’s a choice of 5 different operating modes, a boiler protection option and a night correction.
Due to the commissioning menu and the 4 pre-configured basic systems, configuration is quick and easy.
The chimney sweeper function and the holiday mode can be activated by pressing a single button.
