{"product_id":"huum-uku-wifi-main-module","title":"HUUM UKU Wi-Fi Spare Main Module","description":"\u003cp\u003eThe main module is the box that switches the heater. It mounts outside the hot room, the display panel plugs into it, and the temperature and door sensors wire back to it. This is the Wi-Fi module on its own, sold as a service part rather than as a complete control.\u003c\/p\u003e\n\u003ch2\u003eWhat it does, and what it does not\u003c\/h2\u003e\n\u003cp\u003eThe module carries heaters up to 11 kW by itself. The HIVE 12, 15 and 18 draw more than that and need the UKU extension box alongside it, which is a separate part.\u003c\/p\u003e\n\u003cp\u003eIt is sold without a display panel, without sensors and without cables. If yours failed and took nothing else with it, this is the part you need. If you are replacing a whole control, buy the control rather than the module.\u003c\/p\u003e\n\u003ch2\u003eWhere it is allowed to go\u003c\/h2\u003e\n\u003cp\u003eHUUM's rule is outside the sauna room. Where that is impossible the manual allows it inside, no higher than 4 inches off the floor, at least 6 feet from the heater, ideally under the bench. Its maximum working temperature is 122 F, which is why it never goes high on a hot room wall. Leave the access panel reachable, because it has to be opened to wire anything into it.\u003c\/p\u003e\n\u003ch2\u003eCheck the generation before you order\u003c\/h2\u003e\n\u003cp\u003eThis is the module for HUUM's UKU 4.1 generation, which is the control we sell. HUUM uses different part numbers for the 4.2 generation. The rating label on your own module tells you which you have: the photograph above shows where it reads UKU WiFi and the version, and the two minutes it takes to look are cheaper than a wrong part.\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\u003eHow do I know whether I need the module or the whole control?\u003c\/summary\u003e\u003cdiv class=\"fb\"\u003e\u003cp\u003eThe module is the box that switches power.
