Weather-controlled Controller WDC10B
Weather compensated controller WDC10B

Weather compensated controller WDC10B

Weather compensated controllers WDC10B are designed to regulate space heating and domestic hot water heating in individual houses. They allow the regulation of one or two heating circuits, the switching between heat sources and the protection of the return when the storage tank is filled. They are used for heating systems with one or two boilers, a heat pump, a heat storage tank and a solar system.


  • regulating the radiator space heating system,
  • regulating the underfloor heating or cooling system,
  • regulating a convector heating or cooling system,
  • regulating a wall or ceiling heating or cooling system,
  • heating domestic water.

Key features of the WDC10B controller

  • 7 preset hydraulic schemes,
  • they can be used to regulate new heating systems or to replace existing regulators,
  • heating or cooling rooms according to a timed programme,
  • heating domestic water according to a timetable,
  • regulating storage heating systems,
  • 2 bedroom units can be connected,
  • BOOST function for intensive space heating,
  • 13 language user interface,
  • a wizard to start your device quickly and easily,
  • the ability to simulate sensors and analyse system performance,
  • remote monitoring using SeltronHome.
