Operating manual Sauna control FCU2x00/FCU3x00/FCU4x00 Version V 2.09 7
1.4 Changes and modifications
Changes and modifications to the control unit or to the installation could lead to unpre-
dictable dangers.
The written approval of the manufacturer must be obtained before making any technical
changes and enhancements to the Sauna control.
1.5 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 to for your own safety and the safety
of the unit:
Electric poten-
tial
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 danger-
ous 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 discon-
nection.
– Disconnect the unit from the mains before carrying out any work on
it (switch off the fuse in the distribution box) and secure against re-
starting. Check for zero potential. The control device should be dis-
connected from the mains before opening the casing.
– In case of damage to the insulation, switch off the power supply im-
mediately and carry out the repair.
– Work on electrical unit should be carried out by certified electricians
only.
– Never bypass fuses or switch them off.
– 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 230V/400V 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 junction box. Send the unit back to the fac-
tory for check/repair.

1.6 Information on the operating and installation manual
An operating manual as well as an installation manual are available for the FASEL con-
trol unit.
The operating manual is meant for the user and gives important instructions for handling

The installation manual describes the assembly, installation, commissioning, rectifica-
tion of defects and repair and is provided exclusively for the technical personnel.
To ensure safe operation and working practices, all the prescribed safety instructions
and guidelines have to be followed.
Furthermore, the local accident prevention regulations and general safety regulations
applicable for the fields of use of the control unit are to be adhered to.
The operating manual must be read carefully before switching on the device. The oper-
ating manual as well as the installation manual are an integral part of the product and
must be kept in the immediate vicinity of the control unit so that they are always acces-
sible.

4 Design and function
4.1 Function
Depending on the model, the control unit is suitable for the following modes:
Sauna
Sauna with humidity
Infrared
4.1.1 Sauna
In the "Sauna" mode, the cabin is heated to the desired temperature (set point tempera-
ture) using an oven. In order then to maintain the desired temperature in the cabin, the
control unit switches the heater on and off.
As long as the heater heats, the status display shows "Heater" and the display shows
"Heat-up phase". Once the desired temperature is reached, this message disappears.
The cabin is ready for use.
4.1.2 Sauna with humidity (only FCUx200 and FCUx400)
In the "Sauna with humidity" mode, the cabin is heated to the desired temperature (set
point temperature) using an oven. In addition, the desired humidity (set point humidity)
is generated using an evaporator.
As long as the heater heats, the status display shows "Heater". As long as the evapora-
tor blows "steam" into the cabin, the status display shows "Evaporator".
Control unit with humidity control (with humidistat)
For these control units, the evaporator is controlled by the connected humidistat.
Control unit with time-controlled humidity (without humidistat)
In these control units, the evaporator is time-controlled. The amount of steam is ad-
justed by a numerical value from 1 to 9. If set to "1", steam is blown for a short time into
the cabin. If set to "9", the evaporator runs continuously and produces the maximum
amount of steam.
4.1.3 Infrared (only FCUx400)
For the "infrared" mode, the cabin is heated to the desired temperature by one or more
heat sources (set point temperature). The heat sources can be mounted on the wall or
in the wall. As long as the heat sources are working, the status display "infrared heating
system" lights up.
In addition a base temperature can be adjusted. The sauna oven heats as soon as this
temperature falls below. If this base temperature is reached, the sauna oven turns off.

5.1 Safety and instructions
Electric
potential
DANGER!
Danger to life due to electric potential!
Touching live parts can cause immediate danger to life.
Therefore:
– Control unit should be opened only by authorised electricians.
– Electrical work on the machine should be carried out only by qualified
electricians.
Improper
operation
WARNING!
Improper operation can result in serious injuries!
Therefore:
– Carry out all the operating steps according to this operating manual.
Danger of fire
WARNING!
Danger of injury caused by fire!
Objects on the heater or in the vicinity of the heater can cause a fire
and thus result in injuries.
Therefore:
– Always keep the heater and the area around the heater free of ob-
jects.
Health
hazard
WARNING!
Danger of injury caused by covering the temperature sensor and /
or the humidistat!
Covering the temperature sensor and / or the humidistat could lead to
increased temperatures and humidity. These increased levels could
lead to health hazards or serious injuries.
Therefore:
– Do not cover the temperature sensor and humidistat.
– Ensure free circulation of air.

Operation
18 Operating manual Sauna control FCU2x00/FCU3x00/FCU4x00 Version V 2.09
NOTE!
The temperature and humidity values displayed on the control unit may
vary from that displayed on the thermometers and hygrometers
mounted additionally in the cabin. This may be because of the following
reasons:
Depending on the cabin, temperatures differences of up to 60K and dif-
ferences in the relative humidity of up to 40% can occur from the floor to
ceiling or from the heater to the opposite wall.
Analogue instruments are slower to react than the electronic measure-
ment and display system used in the control unit.
5.2 Turn sauna control on and off
5.2.1 Turn sauna control on
Ensure that the heater, the surroundings and the sensors are free of objects.
1. Turn on the sauna control using the "Control unit ON" key. →See page 11, Fig. 2
2. The set point temperature and the set point humidity (if necessary) of the mode last
selected are displayed. The green lamp of the last selected mode flashes.
3. Select mode according to chapter.5.2.3
5.2.2 Turn sauna control off
PLEASE NOTE!
The electronic components can be damaged by repeated improper
turning off!
Therefore:
– Turn off the sauna control as described.
PLEASE NOTE!
Cabin damage for e.g. mould growth due to premature stopping of
the drying function!
After completion of the "sauna with humidity" mode, the cabin is auto-
matically dried for a certain time at a certain temperature. This drying
function is used to avoid cabin damage such as mould growth.
Therefore:
– Do not stop the drying function prematurely.
– The drying function may only be stopped if the cabin is subsequently
operated in "Sauna" mode.
– If the drying function is stopped accidentally, a message appears on
the display. Start the drying function again by following the instruc-
tions on the display.
