UKU is a sauna control system designed by HUUM, which works with both HUUM sauna stoves and sauna stoves from other manufacturers. The standard style is black, although you can select a different colour or wooden style for an additional charge.
 
The UKU control console makes sauna heating easy and comfortable. You can connect it with your lights/ventilation and steamer functions of your sauna and regulate all of them from the remote control. To ensure a safe sauna experience, UKU is equipped with door sensor, overheating protection and child safety lock. Your wall mounted controller and mobile app will always show you the current temperature of the sauna and let you choose your target temperature - even if you are still on your way home.
 
The GSM connection requires a mobile connection, which is free for the first year then requires an annual fee of 29 euros per year. Alternatively, if your sauna is in range of a WiFi connection then you can use the new UKU WiFi sauna control system, which has no annual fee.
