WXD heating controllers are installed into standard-dimension housings 144×96mm. They are intended for the regulation of room heating and hot water production in single-family houses. They allow for the regulation of one or two heating circuits, switching between heating sources, and the protection of the return line during the charging of the supply device. They are used for heating systems with one or two furnaces, a heat pump, a hot water buffer tank, and a solar system.

Application WXD10

  • Regulating radiator space heating system
  • Regulating floor heating or cooling system
  • Regulating convector heating or cooling system
  • Regulating wall or ceiling heating or cooling system
  • Hot water preparation


Advantage WXD10

  • they are fitted in the housing of standard dimensions of 144 x 96mm,
  • they can be used for regulating new heating systems or to replace already installed controllers,
  • 17 preset hydraulic diagrams,
  • time-program specific space heating or cooling
  • time-program specific sanitary water heating
  • hot sanitary water preparation using a solar system,
  • regulation of heating systems with reservoir,
  • the option of connecting 2 room units,
  • the BOOST function for space heating,
  • 13 language user interface,
  • startup wizard for an easy and quick startup of the device,
  • diagnostics of operation by prompting to errors and exceeded temperatures,
  • the SeltronHome platform connectivity allowing remote control via smartphone or tablet.
