You switch the heater on and off and set the heating time and temperature from a wall-mounted control panel. The UKU can also connect the sauna lighting, ventilation and a steamer, and it has overheating protection and a child lock. Choose the Local version, which is operated only from the panel, or a Wi-Fi version, which can also be controlled from your phone with the HUUM app. The panel comes in black, wood, glass, mirror and gold designs. The sauna heater is sold separately.\u003c\/p\u003e\n\n    \u003ch4\u003eChoose your model\u003c\/h4\u003e\n    \u003cp\u003eThis page covers seven models: UKU Local, UKU Local Wood, UKU 4.2 Wi-Fi, UKU 4.2 Wi-Fi Wood, UKU Glass, UKU 4.2 Mirror and UKU 4.2 Gold.

HUUM says Wi-Fi can be added to a Local unit later through the app, for a fee. The Wi-Fi models suit saunas in areas with Wi-Fi coverage, such as homes, offices or accommodations. With the free HUUM app you can set the start and end time and the target temperature, check the current sauna temperature and get a notification when the sauna is ready. The Wi-Fi module works with 2.4 GHz networks only.\u003c\/p\u003e\n\n    \u003ch4\u003ePanel designs\u003c\/h4\u003e\n    \u003cp\u003eThe Wood panels have a handmade case of thermo-treated ash, and each case has its own grain pattern.
