HUUM UKU 4.2 WiFi Sauna Control — Classic, Black

The HUUM UKU 4.2 WiFi Classic (Black)— HUUM's award-winning sauna controller in its most recent revision. Reads temperature from inside the sauna, controls the heater from the wall panel or your phone, and looks like a piece of interior design rather than an appliance.

WiFi built-in — fire up the sauna from the kitchen, the office, or the car park. Bluetooth-based commissioning takes minutes. Compatible with all HUUM heaters and most Harvia / other Finnish electric heaters up to 18 kW.
