{"product_id":"huum-uku-sensor","title":"HUUM UKU Spare Sensor | Temperature or Door","description":"\u003cp\u003eTwo sensors run with a UKU control. The temperature sensor reads the room and carries the overheating protection the control works from. The door sensor is a sensor and a magnet, so the heater is not left running with the door standing open.\u003c\/p\u003e\n\u003ch2\u003eWhere each one goes\u003c\/h2\u003e\n\u003cp\u003eHUUM is specific about the temperature sensor, because a sensor in the wrong place reports the wrong room. It must not sit above the heater. It goes 20 inches out from the heater's outer edge, 6 inches down from the ceiling, and at least 20 inches from any corner, vent, door or window. In a barrel sauna, where the wall curves away and those distances cannot be met, it goes on the ceiling instead, at the highest point and still 20 inches from the heater.\u003c\/p\u003e\n\u003cp\u003eThe door sensor goes on the handle side of the door frame, no higher than 16 inches from the floor. Higher than that and the heat starts working on the magnet and on the tape that holds it. Recessed into the frame it wants a 13\/64 inch hole. When the door is shut the sensor and magnet sit slightly offset, no more than 13\/32 inch apart.\u003c\/p\u003e\n\u003ch2\u003eWhat is in the packet\u003c\/h2\u003e\n\u003cp\u003eThe door sensor kit is a sensor, a magnet and the double sided tape for the magnet.

If you are replacing a sensor because a cable was damaged, order both.\u003c\/p\u003e\n\u003cp\u003eA heating element is wired inside the heater, so this is a job for the licensed electrician who connected it, not a home repair. HUUM also asks for all of the elements in a heater to be replaced at the same time, because a new element next to worn ones ages quickly.\u003c\/p\u003e\n\u003ch2\u003eQuestions buyers ask\u003c\/h2\u003e\u003cdiv class=\"faq\"\u003e\n\u003cdetails\u003e\u003csummary\u003eWhich sensor has the overheating cut-out?\u003c\/summary\u003e\u003cdiv class=\"fb\"\u003e\u003cp\u003eThe temperature sensor.
