HUUM UKU 4.1 Main Module – Spare Part (Without Control Panel)

The HUUM UKU 4.1 Main Module is a genuine HUUM spare part for UKU 4.1 sauna control systems, available in a Local and a Wi-Fi version. It is the central control unit that manages communication between the control panel, temperature sensor and compatible HUUM electric sauna heaters. The Local version provides dependable on-site control without Wi-Fi. The Wi-Fi version reconnects the control panel, heater and mobile app, so you can start sessions, set timers and adjust temperatures from anywhere. Its sauna-ready electronics are built to handle heat and humidity, and the compact module fits in the existing control housing for a straightforward swap-out with minimal downtime.

Please note: This is a spare part and includes only the main module. Sensors, cables and the control panel are not included.
