Heating controllers

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

DeltaTherm^® HC Heating controller

The heating controller can control a weather-compensated heating circuit, the DHW loading and the backup heating demand for both. With up to five extension modules, further heating circuits, additional DHW functions such as circulation or thermal disinfection, and the efficient implementation of further heat sources 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.
