The Heatmiser Wireless Window / Door Contact Sensor helps reduce unnecessary heating by detecting when someone opens a window or door. Instead of controlling heating directly, the sensor sends a wireless signal to a compatible Heatmiser thermostat or control system. As a result, the heating system automatically reduces output or enters setback mode.
This sensor improves energy efficiency without changing how users operate their heating system. Therefore, installers often add it to both domestic and light commercial installations.
Smart Energy Saving Sensor for Heating Systems
Heating a room while a window or door remains open wastes energy. The Heatmiser wireless contact sensor prevents this by detecting open and closed states. When a window or door opens, the sensor communicates wirelessly with the heating control system.
Consequently, the system responds by reducing or pausing heating output. Once the window or door closes, the system resumes normal operation.
Key Features of the Heatmiser Window and Door Sensor
Automatic Heating Setback on Open Detection
When used with a compatible Heatmiser thermostat, the contact sensor triggers a heating response as soon as a door or window opens. In most cases, the system switches the heating into setback or reduced-temperature mode.
As a result, the system minimises energy waste without requiring user intervention.
Wireless Battery Powered Design
The Heatmiser Wireless Window / Door Contact Sensor runs on batteries and communicates wirelessly. This design allows flexible placement without additional wiring. Therefore, installers can fit it easily in retrofit installations and existing properties.
Battery power also allows quick, clean, and non-invasive installation.
Seamless Integration with Heatmiser Controls
Heatmiser designed this sensor to integrate seamlessly with selected Heatmiser thermostats and control systems. After pairing, it becomes part of the heating logic while preserving normal thermostat operation.
Because Heatmiser manufactures the sensor as a genuine accessory, users can rely on full compatibility and long-term reliability.
