Weather compensated controller WXD10B

The WXD heating controllers are installed in standard 144 x 96 mm housings. They are designed to regulate space heating or cooling and domestic hot water heating in detached houses. They allow the control of one or two heating circuits, switching between heat sources and return protection 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.

Use

  • 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.
