The heatmiser 'Wireless Window/Door Contact Sensor' is designed to switch your heating system to standby whenever a window or door is opened. The heating will remain off until the window/door is closed.

With multiple zone heating control systems the sensor can shut off the radiators/ underfloor heating for an individual room.

Multiple 'Wireless Window/Door Contact Sensors' can be paired to homes with just a single thermostat.* Which ever sensor breaks its contact the entire system will switch to standby. Only when all contacts are closed will the heating resume.

The Wireless Window/Door Contact Sensor is compatible with the Edge Thermostat Series and can be used to switch the heating off whenever a window or door is opened.

Up to 16 Contact Sensors can be paired to a single Edge Thermostat*

*Assuming no Wireless Air Sensors in use.

This Sensor is designed to be surface mounted.

  • To release the battery cover push down and slide in the direction of the arrow.
  • Remove the plastic tab between the battery and the contacts, then return the battery cover until it clicks into place.
  • Peel back the film from the adhesive pads on both the 'Contact Sensor' and the 'Magnetic Strip'.
  • Attach the 'Contact Sensor' to the framework and the 'Magnetic strip' to the window/door, making sure that the 'Magnet' is positioned on the opposite side of the 'Pairing Button', and no more than 5mm apart.

The recommended maximum distance between the 'Window/Door Wireless Contact Sensor' and the heatmiser compatible receiver is 40 meters.
