The Wiessee medicinal springs "Adrianus" and "Königin Wilhelmina" are the strongest iodine and sulphur springs in Germany and have been used for therapeutic purposes since their discovery in 1910. In order to be able to continue to benefit from this healing water with all senses in the future, the springs have been renovated and redesigned with the iodine-sulphur bath.

In 2013, the internationally acclaimed architect Matteo Thun began developing a new spa district concept in Bad Wiessee. Now a new bathhouse with a modern, nature-oriented design has been built in the spa district just a stone's throw away from the former iodine-sulphur bath. The opening took place in June 2020.

In May 1909 a spring was drilled in the course of oil drillings. Thanks to the Wiessee physician Dr. Erwin von Dessauer, it soon turned out that this was Germany's strongest iodine sulphur spring, whose water was ideally suited for balneological purposes. Just one year later, on 22 July 1910, the first original Wiessee medicinal baths were administered. Thus in 1912 the first bathhouse was built. This was followed by the development of the Wilhelmina spring (1930) and the Adrianus spring (1978). In the meantime, the inhalatorium and a department for eye treatments were expanded and the spraying bath was introduced as a new application. Finally, in 2001, the community of Bad Wiessee took over the operation of the iodine sulphur bath until today.

The bathhouse is divided into four areas. The lighting is controlled at the reception via an iPad with our IPMS visualization, and for each area separately via WT-G Wall-Touches also at the receptions. In addition, there are JUNG 8-way buttons next to the entrances to the bath cabins to control the lighting and ventilation of each cabin. The lighting in the secondary rooms as well as in the corridors is operated via push-buttons.

In the healing water conditioning building, the following is controlled, displayed, monitored and recorded on a Server Touch-PC using a clear and convenient IPMS visualization:

• Filling levels of the two medicinal water tanks
• Removal quantity of medicinal water via flow meter
• Temperature measurement of the medicinal water
• Measurement of the electrical conductivity of the medicinal water
• Control of the feed pumps "Wilhelmina" and "Adrianus" spring
• Measurement of the feed rate for both pumps
• Control of the pressure increase of the medicinal water
• Monitoring and control of the gas storage tank and flare

In the bathhouse the following can be controlled and monitored:

• Control of buffer storage
• Regulation of the medicinal water heating for the tub bath and spray bath
• Heating control (room regulation, underfloor heating)
• Control of the ventilation and fire dampers
• Release of water flow in the outside well

Furthermore, in the bathhouse, the motors of the roof domes, the sun protection and the windows are also controlled via the ISYGLT system and automatically closed in case of rain and/or wind. Our weather station is used hereby for weather monitoring.
