With the KLAFS sauna app you can start your SANARIUM® while you’re out and about. That way you don’t have to wait for the warming-up phase to end. Instead the SANARIUM® is ready and waiting, heated to your desired temperature. Switching on and off, checking its status, time presets and regulating humidity: our app offers all these convenient features, as well as providing a handy sauna and wellness glossary plus plenty of useful information. The app has been designed for use with the SANARIUM® fitted with the 18033 control panel or TOUCHCONTROL and can be used with all standard smartphone operating systems. All the KLAFS sauna app programs and operating features are as intuitive and user-friendly as our control panels, and several different users can communicate with the SANARIUM® from their smartphone. Furthermore, to protect against incorrect use the KLAFS ASC safety system is ensuring that the SANARIUM® can only be controlled remotely after it has checked the operations chosen. From now on the KLAFS sauna app means your wellness program is available to you when you’re on the road, without compromising on safety.
