lowing general safety instructions during mounting, configu-
ration and commissioning of the product.
Risk to life and limb and risk of fire
Risk to life and limb from electric shock and fire in the event of im-
proper or faulty electrical connection. This risk remains also after
completion of the installation work.
The electrical installation of the control unit and other electrical
systems or equipment with a fixed mains connection may be
performed only by a trained electrician from an authorised elec-
trical company.
Ensure compliance with the applicable standards and regula-
tions for electrical installation.
The system must be completely disconnected from the mains
supply before commencing installation and repair work.
The housing cover must only be removed by a trained special-
ist.

EOS Compact D18/H18 - Installation and Operating Instructions EN-7
General safety instructions
Fire hazard from overheating
Insufficient ventilation can lead to device overheating and fire.
Do not install control panels, relay boxes and modules in en-
closed cabinets or wood panelling.
Observe the sauna heater manufacturer’s safety and installa-
tion instructions.
Observe the cabin manufacturer’s safety and installation in-
structions.
Touchable glass surfaces on the outside of the cabin must not
exceed 76°C. Provide a protective system if needed.
Damage to the unit
Corrosive or heavy saline atmospheres damage the contacts in the
control panel, in the relay box and in the sensors.
The control panel and sensors should not be installed in a cor-
rosive or heavy saline atmosphere.
Damage due to incorrect mounting location
The control unit is not suitable for outdoor use.
It must be operated only inside buildings and may not be ex-
posed to environmental conditions such as extreme humidity
and moisture or the possible formation of condensation or cor-
rosive substances in the ambient air, as well as other weather
conditions.
Similarly, excessive cold and extreme exposure to sunlight must
be prevented.
Protect the unit accordingly if there is an increased risk of me-
chanical damage.

EN-8 Installation and Operating Instructions - EOS Compact D18/H18
EN General safety instructions
1.2 Operator instruction
The operator of the sauna cabin must be instructed in the general safety
instructions during commissioning. The operator must be given a copy of
the operating instructions.
The operator must make the end user aware of safety instructions that are
relevant to the end user.
The operator must be familiar with the settings for the heating period and
understand how it is controlled.
Fire hazard
Objects left on the heater and/or directly in front of an
IR emitter can catch fire and lead to fires.
Do not place objects on the heater and/or directly
in front of an IR emitter.
Fill the rock store as directed.
Inspect the sauna cabin prior to each commissioning.
If you switch on the heater using pre-set timers or a remote con-
trol, attach a protective cover to the heater or install a suitable
safety system.
When using control units with a remote control* option (see
EN 60335-1), protection from switching on a covered sauna
heater is required.
* Remote control = setting up, controlling and/or regulating a
device with a command that can be given outside of the visual
range of a device, whereby the transmission media such as tel-
ecommunication, audio engineering or bus systems are used;
also included are pre-set timers and weekly timers.

General safety instructions
Risk of electric shock
A risk to life and limb from electric shock and fire arises in the event
of improper repair work. This risk remains also after work is com-
pleted.
The housing cover must only be removed by a trained special-
ist.
Repairs and installations must only be performed by a trained
specialist.
The system must be completely disconnected from the mains
supply before commencing repair work.
Use only original spare parts from the manufacturer.
Health risks
Spending time in an infrared or sauna cabin can lead to serious
health risks or even death for persons with health impairments.
Persons with health impairments who spend time in a sauna
must consult a doctor before entering an infrared or sauna cab-
in.
Equipment damage due to overuse
Excessive humidity in commercial infrared or sauna cabins can
lead to property damage.
In a commercial infrared or sauna cabin, the heating period
must be set so that it switches off automatically after a specific
period of time.
If the heating does not switch off automatically after a defined
heating period, cabin use must be supervised at all times.
Inspect the cabin before each use.

selves at risk.
Children must be supervised to ensure they do not play with
the unit.
Children under 8 years of age should not operate the sauna
cabin.
The settings for the heating time must only be changed by chil-
dren under 8 years of age if they are supervised by an adult.
The sauna cabin must only be used by persons with reduced
mental capacity, or limited physical or sensory abilities under
supervision or if they have been previously instructed in its use
and understand the risks.
Children and persons who have not received proper instruction
must not clean or service the system.

The temperature/humidity in the sauna cabin is set via the control unit. The
set values are checked by the sensor. The heater sensor controls the tem-
perature in the sauna cabin. The heater sensor has a safety temperature
limiter, which ensures that the temperature does not exceed 140°C.

EN Identification
Bench sensor (optional, EOS Compact D18/H18)
You can improve heat distribution in very large saunas where air circulation
is a challenge by using an additional bench sensor.
If a bench sensor is installed, it assumes control of the temperature. How-
ever, the heater sensor does not control the cabin temperature, rather it
limits the temperature within the maximum permissible range via the
heater. Exceeding the permissible temperature range would trigger the
safety temperature limiter.
If the bench sensor fails, the heater sensor regulates the temperature.
Multisensor (optional, for EOS Compact H18 only)
The multisensor is a special sensor that can function as a humidity sensor
and a temperature sensor (bench sensor). The multisensor checks either
the humidity or the temperature in the sauna cabin. In Bi-O mode, the mul-
tisensor controls the relative air humidity in %. At the same time, the con-
trol unit attempts to keep the set humidity as precisely as possible.
If the sauna is in Finnish mode, the temperature is measured and con-
trolled, not the humidity.
The heater sensor continues to monitor the temperature behaviour and
only intervenes for safety reasons when it is necessary prevent overheating
via the heater.
If the multisensor fails, the heater sensor regulates the temperature.

3 Installation
3.1 Routing the lines
All lines should be routed before installing the control unit. The connec-
tions can be plugged in after installation, since the control unit’s front
panel can be removed.
NOTICE
Electronics malfunctions
Routing data and power supply lines together can lead to elec-
tronics malfunctions because, e.g. because the sensor will not be
detected.
Do not route sensor and sauna bus lines together with power
supply lines.
Lay data and mains leads in separate cable channels.
Data lines must be routed and connected in such a way that they are not
openly accessible. They should be routed between the insulation and the
outer wall of the cabin. Cabin insulation must be installed in such a way
that the temperature in the area in which cables are routed
cannot exceed 65°C.
If the data lines are installed outside on the wall, they should be protected
by a cable duct.
Data line(s) routing

Additional lines
If an optional module is connected, a 6P6C line with RJ12 jack is required.
This line is available in various lengths.
See Connecting cables for add-on modules, EN-17.
3.2 Installation site
The control unit may be mounted only outside of the sauna cabin. Observe
the following guidelines.
WARNING
Risk to life and limb and risk of fire
Risk to life and limb from electric shock and fire in the event of im-
proper or faulty electrical connection. This risk remains also after
completion of the installation work.
Do not mount the control unit in enclosed cabinets or wood
panelling.
