Presentation


AHC40 is a compact weather compensated heating controller, installed in the motor housing. It allows a direct mounting on over 20 types of mixing valves of various manufacturers. The controller may also be used with the outdoor sensor, but in that case, the room unit must be installed.

Application AHC40


  • The AHC controller is used in demanding room heating and cooling systems as an extension controller (it is possible to link several controllers into a complex system with a BUS connection)
  • For controlling simpler heating systems with one mixing circuit system

 

Advantage AHC40


  • you can use it as an expansion controller in more complex space heating or cooling systems,
  • you can use it for control of simple heating systems with a single mixing circuit,
  • built in the actuator housing with direct mounting onto the mixing valve,
  • innovative connector system for connecting sensors,
  • direct installation to more than 20 mixing valves,
  • adjustable return flow temperature,
  • 2 preset hydraulic diagrams,
  • multiple controllers can be interconnected into a complex system using the BUS connection,
  • for configuration and monitoring, it is fitted with a graphic capacitive OLED touchscreen display
  • the option of connecting 1 room unit,
  • the SeltronHome platform connectivity allowing remote control via smartphone or tablet.
