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 effi cient implementation of further heat sources are possible. With extension modules, further heating circuits can be controlled. Due to the fl exible application and extension possibilities, the heating controller is also ideal for larger objects such as apartment houses, residential homes and industrial buildings.

  • Up to 5 EM extension modules can be connected via the RESOL VBus® (45 sensors and 39 relays in total), up to 7 weather-compensated heating circuits
  • 2 inputs for digital Grundfos Direct Sensors™
  • 2 inputs for analogue Grundfos Direct Sensors™
  • Screed drying function
  • Data logging, storing, easy transfer of controller adjustments prepared and firmware updates via SD card
  • Cooling over the heating circuit with condensation detection by means of a dew point switch
  • Modulating heating control with 0-10 V boiler control
  • Weather-compensated control with room infl uence or demand-based room control with up to 5 room temperature sensors per heating circuit
  • Remote access with a room control unit or the VBus®Touch HC App
