Heatmiser Thimble Air Sensor The Heatmiser Thimble Air Sensor is a discreet remote air temperature sensor, designed for compatibility with all Heatmiser thermostats that accept remote sensors. The sensing element is housed in a compact ‘thimble’ enclosure, intended for surface mounting on a backplate or ceiling tile, placed within the natural airflow of the room for accurate temperature readings. Sensor Type: NTC 10K, precision air temperature measurement Cable Length: Supplied with a 2m cable (can be extended up to 20m) Dimensions: Diameter 10mm (excluding collar), depth from wall 18mm Mounting: Surface mount—ideal for installation on backplates or ceiling tiles, out of direct sight Compatibility: Works with all Heatmiser thermostats supporting remote sensors, including Neo and Slimline ranges Operating Environment: Not suitable for bathrooms or areas with condensation IP Rating: IP20 This sensor is perfect for measuring air temperature in spaces where a wall-mounted thermostat is not desirable or possible. It enables precise, remote air sensing to optimise comfort and energy efficiency. Box Contents: Heatmiser Thimble Air Sensor 2m Sensor Cable (pre-attached) Installation guide
