DeltaTherm<sup>®</sup> HC mini Heating controller

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. Additional DHW functions such as circulation or thermal disinfection, and the efficient implementation of further heating circuits are possible with EM Extension modules*. 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.
In summer, the heating circuit takes over the demand-based cooling by means of a humidity sensor for dew point calculation*.
