1.2 Technical safety notes for assembly and installation
– DANGER!
– The control device can be installed directly on the outer side of the
cabin or at another location, however not within the cabin
– Use the sauna control device only with a cover guard for sauna
heaters if one of the following option is enabled:
timer option (lockable in service menu)
remote start via option input, W B-Control or App
– Appropriate VD applies to public saunas, that a control lamp,
showing, that the heater is switched on, is to install in the room of the
supervisor.
– This lamp can be connected to the clamp (FL -STB).
– For switching off the mains, the power supply cable must be
equipped with a fuse with a contact opening width corresponding to the
requirements of the excess voltage category III for total disconnection.
– At FCUxxxx the main switch of the control unit must be accessible.
– The sensor of the thermostat must be installed in such a way that it is
not affected by the incoming cool air.
1.3 Intended use
Depending on the version, the FAS L sauna controls of the series FCU2x00, FCU3x00 and FCU4x00 are
exclusively meant for operation and control of saunas, saunas with moisture and infrared cabins. The control
devices are permitted for operation in houses and commercial facilities.
Intended use
WARNING!
Danger if not used correctly
Any improper use of the sauna control can lead to dangerous situations.
Therefore:
– Use the sauna control correctly.
– Operate the sauna control only within the permissible room
temperature and moisture range.  See technical data
– All the specifications in the operating manual and the installation
manual must be strictly adhered to.
Claims of any type due to damages caused by improper use will not be accepted. Only the user is
responsible for damages caused by improper use.
1.4 Modifications and alterations
Modifications and alterations of the sauna control or installation can lead to unforeseen dangers.
All technical modifications and add-ons to the sauna control require the written permission of the
manufacturer.

Safety
Installation instructions Sauna control Series FCUxx00 / Version V 2.27 7
1.5 Demands on technical personnel
The assembly, installation, commissioning as well as rectification of defects and repairs
must be carried out by qualified persons only unless otherwise mentioned.
Inadequate
Qualification
WARNING!
Danger of injury due to inadequate qualification
Improper handling can lead to significant personal injuries and material
damage.
Therefore:
– The assembly, installation, commissioning as well as rectification of
defects, maintenance and repairs must be carried out by qualified
persons only unless otherwise mentioned.
 Technical personnel
Due to their technical training, knowledge and experience as well as the knowledge
of the relevant regulations these persons are in a position to carry out the tasks
assigned to them and to identify possible dangers on their own. Also they are
familiar in handling with SD sensitive devices.
 Certified electricians
Due to their technical training, knowledge and experience as well as the knowledge
of the relevant standard specifications and regulations these experts are in a position
to carry out jobs on the electrical unit and to identify possible dangers on their own.
In Germany certified electricians have to fulfill the stipulations of the accident
prevention regulation BGV A3 (e.g. master electrician). In other countries
corresponding stipulations are applicable that have to be followed.

1.6 Operational safety and special dangers
– Pay attention to the safety and warning notes in the following chapters of this manual to
minimize health hazards and to avoid dangerous situations.
The following instructions are to be adhered for your own safety and the safety of
the unit:
Electric
potential
DANGER!
Danger to life due to electric potential!
Contact with live components can be fatal.
Damage of the insulation of the individual components can be
dangerous to life.
Therefore:
- For switching off the mains, the power supply cable must be
equipped with a fuse with a contact opening width corresponding
to the requirements of the excess voltage category III for total
disconnection.
- Disconnect the unit from the mains before carrying out any work
on it (switch off the fuse in the distribution box) and secure
against restarting. Check for zero potential. The control device
should be disconnected from the mains before opening the casing.
- In case of damage to the insulation, switch off the power supply
immediately and carry out the repair.
- Work on electrical unit should be carried out by certified
electricians only.
- Never bypass fuses or put them out of operation.
- While replacing fuses, pay attention to correct current
specifications.
- Keep moisture away from live components, since it can lead to
short circuit.
WARNING!
If a short circuit occurs in a 23 V/4 V load, the relay contact can
be welded by the high short-circuit current. Is turned on before
removing the short circuit, the safety relay can be also welded.
This can lead to the continuous operation of the load. Turn off the
circuit breaker in the distribuition box. Send the unit back to the
factory for check/repair.
Improper
operation
WARNING!
Improper operation can result in serious injuries!
Therefore:
read and note the operating manual.

cables –
Electric
potential
DANGER!
Danger to life due to electric potential
Use of inappropriate cables can lead to short circuits and subsequent
fires.
Damage to the insulation can be dangerous to life.
Therefore:
– All the cables, which lead to the sauna, must be designed for at least
150 °C.
– When laying the cables in the ground, it is essential to use a cable
approved for underground installation. Signal lines must be routed in
a separate trench, not in the same trench as the 230 / 400V lines.
– Use cables as per specifications in Table 2 and electrical circuit
diagram (see annexure). The specified cross sections are designed
for copper cables. In case of aluminum cables the cross sections
should be appropriately increased.
– The cross sections can increase due to the length of the cables, the
type of cable laying or special regulations.

5 Installation
5.1 ESD protection
– ATTENTION!
– Note ESD protection!
– Do not touch on electrical parts because of SD protection reasons.
When assembling only touch the circuit board at the plastic case or at
the edge of the board.
– Also only touch the connection cable to the circuit board, on the
connector. Thereby do not touch the contact surfaces.
Therefore:
– Take appropriate protections. Touch a grounded piece of metal as a
minimum protection.
5.2 Installation of sauna control device FCUxxxx
Installation The sauna control device should be installed sideways, above and below at a distance
of at least 5 cm from the walls or other equipment. There should be a distance of 10 cm
between other electrical devices.
The sauna control device must be mounted on a closed surface (no grid structure) so
that no electrical parts can be touched through the openings in the rear panel.
The control unit must be mounted so that it is at any time accessible! (e.g. for service,
wear parts, fuses, etc.)
Note!
At FCUxxxx-Design-Glas the ain switch of the control unit ust be
accessible.
5.3 Installation of the operating control of FCUxxxx-Design (-…..)
Installation The operating control can be installed maximum 100 m away from the basic control
device.
ATTENTION!
Damage or malfunction of the operating control FCUxxxx-Design-
Glas by steam, humidity or water!
– Therefore:
– It must be ensured, that neither steam, humiditiy or water can occur
at or in the keyboard.

5.8 Installing the temperature and humidity sensor
Note!
An installation of a hu idity sensor with hu idity control is necessary
only for the bathing option "Sauna with hu idity ". If a ti e controlled
hu idity control is provided then a hu idity sensor is not necessary.
Note!
The sensor of the ther ostat ust be installed in such a way that it is
not affected by the cool inco ing air.
Note!
The te perature and hu idity values displayed on additional
ther o eters and hygro eters in the cabin can deviate fro the
displayed values on the control. This could be due to the following
reasons:
Depending on the cabin, the te perature differences fro the floor to
the ceiling or fro the oven to the opposite wall can be up to 60 K and
the differences in the relative hu idity can be up to 40%.
Instru ents with indicator needles react slower than electrical
easuring and display syste s used for the control.
