It is indeed important to note that digital sauna controls are normally only intended for indoor use and are not suitable for direct use in outdoor saunas. This is because digital controls are more sensitive to humidity and weather conditions that can occur outdoors
Digital sauna controls are usually designed for a low humidity environment, which is common indoors. When used outdoors, they may be affected by higher humidity, condensation or direct exposure to water. This can lead to malfunction, damage or even safety hazards that are not covered by the manufacturer's warranty.
If you want to use a sauna control outdoors, it is advisable to use analogue controls and mount them in a suitable protective housing or box. These housings protect the control from moisture and the effects of the weather and ensure safe and reliable functionality.
