2.6 Intended use
This heater is intended solely for the purpose of heating sauna cabins,
together with a suitable control unit.
EOS Vision/Vision Stone is suitable for commercial and private use.
The heater is not suitable for outdoor use.
It must be operated only inside buildings and may not be exposed to envi-
ronmental conditions such as extreme humidity and moisture or the possi-
ble formation of condensation or corrosive substances in the ambient air,
as well as other weather conditions.
Any use beyond this is considered improper use. Proper use also includes
compliance with operating, maintenance and servicing requirements.
Foreseeable misuse
The following are considered instances of foreseeable misuse:
The heater power does not match the sauna volume.
The control and sensor cable plugs are plugged in incorrectly.
The unit is operated without knowledge of or compliance with the
safety instructions.
Operating, service and maintenance requirements are not observed.
The unit is operated after technical or other modifications are made to
the relay box.
The unit is operated with insufficient air supply or exhaust air.
The unit is operated without sauna stones or with a rock store that is not
filled as directed.
The unit is operated by children under 8 years of age.
The unit is operated by children 8 years of age or older, or persons with
reduced mental capacity who have not been thoroughly instructed in
its use.

General instructions
Please note that an optimal sauna climate can be achieved only if the
cabin with its air inlets and outlets, the sauna heater, and the control
unit are synchronized.
Observe the specifications and information provided by your sauna
retailer.
The sauna heaters heat the sauna cabin with heated convection air.
Fresh air is drawn in through the air inlet. It is warmed and rises (convec-
tion) and is then circulated in the cabin. Some of the used air is pushed
out of the cabin through the cabin's air outlet. This creates a typical
sauna climate in which temperatures of approx. 110°C are achieved
directly below the ceiling. These temperatures drop to approx. 30–40°C
in the cabin along the floor. Therefore, it is not unusual that if the tem-
perature sensor above the sauna heater reads 110°C, the thermometer
that is mounted approx. 20–25 cm below the cabin ceiling on the cabin
wall reads only 85°C.
When the max. temperature is set for the area around the upper sauna
bench, the bathing temperature is typically between 80°C and 90°C.
Please note that the highest temperatures in the cabin are always above
the sauna heater and that is where the temperature sensor and safety
temperature limiter should be mounted according to the installation
instructions.
The first time the cabin is heated, you may notice a slight odour result-
ing from the evaporation of consumables used in the manufacturing
processes. Air out your cabin once it has been heated and before using
the sauna.

3.1.3 Temperature sensor
It is essential that the temperature sensor with the safety temperature lim-
iter (STB) is installed.
The temperature sensor with the safety temperature limiter is not included
in the scope of delivery.
WARNING
Risk of fire due to incorrect temperature sensor position
Overheating can occur if the temperature sensor is installed in the
incorrect position; in this case, the sensor may read a lower tem-
perature than actually exists in the cabin.
This would trigger the sauna heater to continue to heat, even
though the desired temperature has already been reached.
Install the sensor as shown in the figure Dimensions in the
cabin, EN-16.
The temperature sensor must be installed where expected temperatures
are the highest, meaning above the heater.
