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.

  • 4 pre-configured basic systems
  • 12 pre-programmed schemes for the temperature controls classes II, III, V, VI, VII and VIII
  • 4 relay outputs (incl. 1 potential-free extra-low voltage relay)
  • 5 inputs for Pt1000 temperature sensors
  • 5 operating modes, boiler protection, room thermostat and night correction
  • Holiday mode, chimney sweeper function and screed drying function via microbuttons
  • Data logging, storing, easy transfer of controller adjustments prepared and firmware updates via SD card
  • Modulating heating control with 0-10 V boiler control
  • Weather-compensated control with room influence or demand-based room control with up to 3 room temperature sensors
  • Remote access with a room control unit or the VBus®Touch HC App
