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

DeltaTherm® HC Plus Heating controller

Availability expected as of quarter 4/2024
The DeltaTherm® HC Plus can control 2 weather-compensated heating circuits and their backup heating demands. 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. In summer, the heating circuits take over the demand-based cooling by means of a humidity sensor for dew point calculation.
