HUUM UKU extension box for heaters up to 36 kW

The HUUM UKU extension box is an add-on for the UKU sauna control system. It is used when the output of the sauna heater exceeds the capacity of the power controller, and ensures safe and reliable operation.

The UKU power controller handles heaters up to 18 kW and the extension box adds another 18 kW. Together they control heaters with an output of up to 36 kW. Control stays the same: from the wall-mounted panel and, with the UKU WiFi system, also from the HUUM mobile app.

Order the HUUM UKU extension box in the GREUS online store. We will gladly help you choose the control for high-output heaters.

Note: the extension box does not work on its own; a HUUM UKU set with a power controller is required. HUUM electric heaters up to 18 kW do not need the extension box, the standard HUUM UKU set is enough. Electrical installation may only be carried out by a qualified electrician.
