UKU CLASSIC Local Sauna Controller is both stylish and durable, made from high-quality plastic. Its minimalistic design makes it easy to use.

It lets you start heating the sauna and control all the necessary functions. The control panel is also available in different colors, so you can choose one that best matches your sauna’s interior design. The panel is equipped with a child lock for added safety.

The UKU 4.2 offers a smarter, safer, and more precise way to control the sauna. One of the most notable updates is the inclusion of two sensors: a safety sensor (previously referred to as the temperature sensor) and a new bench sensor.

• Safety Sensor – Helps keep the temperature near the sauna heater under control.
• New Bench Sensor – Measures both temperature and humidity at bench level, where sauna users experience the heat. While installation is optional, it provides more precise readings and an enhanced sauna experience.
• Simplified Cabling – The updated set includes a long, heat-resistant cable that can be used for the control panel, sensors, and door contact sensor.
• Upgraded Door Sensor Kit – Provides greater installation flexibility and improved long-term reliability.

UKU sauna control system has won the most prestigious Red Dot product design award for its functionality and design in 2021.

• Easy to Use
• CE Certificate
• Safety and Control
• Made in Estonia

UKU sauna control panel works with HUUM Sauna Heaters over 11kW and up to 18kW but can be used with other manufacturers' heaters. A UKU Extension Box is required for heaters over 10.5kW.
