Heatmiser - Window / Door Contact Sensor

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.
