The HUUM UKU 4.1 Sauna Control System (Without Panel) is the main module of a UKU control setup, handling communication between the control panel, temperature sensor and compatible HUUM electric sauna heaters. It comes in a Local or a WiFi version; the control panel is not part of this listing. The Local version works with UKU CLASSIC, GLASS and WOOD panels.
Pick Local for on-site operation with no Wi-Fi connection, in a new installation, upgrade or replacement. The WiFi version links panel, heater and mobile app, so sessions, timers and temperature can be set from anywhere; its electronics tolerate continuous heat and humidity, and the compact module fits the existing control housing.
Please note: This package does not include the control panel. You will need to purchase a compatible panel separately.
