Use the digital readings on the control unit or the interior display as a guide. The values on the thermometer are measured analogue and are therefore less precise. For safety reasons, the temperature sensor with the overheating protection is placed on the cabin ceiling above the oven, which is normally the hottest spot. This can lead to temperature differences between the sensor and the cabin thermometer of max. 10 to 15° C. The value on the interior display or the binding digital measured values on the control unit are decisive for the cabin climate.

Nowadays, saunas are highly technical. Because preselection and remote selection also involve certain risks, fire protection is enormously important. At Küng, all programmable sauna models are equipped as standard with a barely visible, intelligent magnetic door contact sensor that ensures that sauna programmes can only begin when the door is closed. Any opening of the sauna door automatically deactivates the programmed process. This prevents anyone from unintentionally leaving an object in the sauna as a potential cause of fire between the time you enter the desired programme and the time of its pre-programmed start. The immediate interruption of the programme or the heating phase would prevent the worst - so you as a sauna owner can always be unconcerned in your absence.

In the case of wood containing resin, resin may sporadically escape at high temperatures. This can be easily scraped off when the wood is cold. However, this also removes the pleasant scent of the resin. Attention: A strong resin leakage is often a sign of overheating of the sauna.

Before the first sauna bath, it is recommended to preheat the sauna to 70° for approx. 2 hours. Temperatures above 80° should be avoided during the first time.

The water container must be filled before each sauna session. The sauna programme may only be started when the container filled with hot water is on the heating plate. The ideal filling quantity is approx. 2/3. If there is no water or too little water, the dry-running protection of the system switches on. After cooling down, it is recommended to empty and clean the water tank.

Of course, this depends largely on the size and equipment of the sauna! With an average power of 9 kW, the costs for a sauna evening of 3 hours amount to just under four euros (CHF 4.00).

The sole purpose of a heater guard is to protect the sauna bathers. Whether it is necessary depends on the location of the heater, the conditions of the sauna room and the type of user. If children are using the sauna, for example, a heater guard is strongly recommended.

The interval for replacement depends primarily on the frequency of use. Due to the high temperatures followed by the cooling down caused by the infusion, the sauna stones are subject to a high degree of wear (even small chips are possible). In addition, unsightly lime residues and additives from infusion concentrates are deposited on the stones. For these reasons, it is necessary to check sauna stones regularly and replace them if necessary.

The so-called peridodite stones have an excellent heat storage capacity and conductivity. To ensure this for as long as possible, the stones must be loosely layered in the basket to ensure good air circulation. Insufficient air circulation causes the temperature of the heating elements to rise dramatically. This means an increase in energy consumption due to longer heating phases and a shortening of the life of the heating elements.

The sauna heat does not only come from the stove, but it acts as radiant heat from all wooden parts, i.e. walls, benches and the ceiling. For this, it is necessary that the sauna cabin is preheated for a sufficiently long time, because the wood needs longer than the surrounding air until it has heated up accordingly. If you start to sauna before the wood has adjusted in temperature and emits radiant heat, you deprive yourself of an even heating of the body - the sauna effects would be impaired. In concrete terms, the preheating time of the sauna takes between 25 and 60 minutes (depending on the programme selection and room conditions).
