The Huum UKU 4G is a sauna control system that is connected to a mobile cellular network via 4G connection. Thus if no wifi or other internet connection is available, this connects directly.
This control unit can also be connected to sauna heaters from manufacturers other than Huum, such as Sawo NS-model sauna heaters.
You will not need the extension box if the sauna heater has power less than 18 kW.
