Heating controllers

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

DeltaTherm^® HC MAX Heating controller

The DeltaTherm^® HC MAX can control up to 4 weather-compensated heating circuits, the DHW loading and the backup heating demand for both. Additional DHW functions such as circulation or thermal disinfection, and the efficient implementation of further heat sources are possible. With extension modules, further heating circuits can be controlled. Due to the flexible application and extension possibilities, the heating controller is also ideal for larger objects such as apartment houses, residential homes and industrial buildings.
