Dear customer,
with this IR-control unit, you have received an
advanced electronic device, which was devel-
oped and manufactured to meet to the highest
quality and safety standards.
The following operation instructions describe
how to use the control unit.
Read these instructions carefully and keep it for
future references, in order to quickly and easily
operate your infrared cabin.
General Information
The IR control unit is designed for a power sup-
ply of 230 V 50 Hz and must be separately pro-
tected with 16 A.
According to the valid regulations, the electri-
cal connection of the control unit and the elec-
tric components has to be carried out through
the specialist of an authorized electric shop.
Please check the regulations according VDE
0100 Part 703/2006-2.
To ensure a reliable and trouble-free operation
please read the following installation guide-
lines and manual. Make yourself familiar with
all operation steps.
Make sure to also observe the specications
and instructions of the cabin manufacturer.
Note!
Connecting the mains inputs L1-L3 to only
one phase is not permitted!

General safety precautions
• This device can be used by children aged
8 upwards and by persons with physical,
sensory, or mental disabilities, or who
have inadequate experience and knowl-
edge if they are supervised or if they have
received adequate instruction in how to
use the device safely and understand the
associated risks. Children may not play
with this device. Children may not clean
or carry out any user maintenance if un-
supervised.
• Children are to be supervised in order to
make sure that they do not play with this
device.
• !Attention: It is forbidden to install
the control box in a closed switch cabinet
or behind a wooden panelling!
• The electrical installation may be done
only by a qualied electrical technician.
• You must comply with the regulations of
your power supply company and the ap-
plicable local legal regulations, such as
e.g.VDE regulations (DINVDE 0100).
• !WARNING: Never attempt repairs or
installations by yourselves, as this could
result in serious injury or death. Only a
qualied technician is allowed remove
the housing cover.
• Please note the dimensions in the assem-
bly instructions, especially when installing
the temperature sensor. The temperature
above the oven is critical for the temper-
ature setting. The temperature can be
held within operating parameters and a
minimal temperature gradient inside the
the cabin can be achieved only if unit is
installed correctly.
• The device may only be used as intended
as a control unit for IR radiators or IR heat-
ing foils.
• !Only the IR radiators or heating foils
with the integrated overheating protec-
tion 140°C compliant with the EN 60335
norm are permitted to be used.
• Completely disconnect the control unit
from the electrical circuit, i.e. ip all circuit
breakers or the main circuit breaker during
each installation or repair.
• Please observe the safety and installation
information of the manufacturer of the IR
heating equipment.
• Make sure to also observe the specica-
tions and instructions of the cabin manu-
facturer.

Installation of the control unit
Wall installation
The control unit may only be mounted outside
the IR-cabin. It is advisable to select the out-
side wall of the cabin to which the IR-radiator
is xed from the inside as mounting position.
If ductwork is already provided for electrical in-
stallations then the position of the control unit
is predetermined by that. Please follow the in-
structions for installation:
Fig. 1
1. The 3 mm diameter boreholes for the sup-
plied wood screws 4 x 20 mm are drilled ac-
cording to the dimensions shown in Fig. 2 +
3.
2. Insert one of the wood screws into the top
center hole. The control unit is hooked onto
this screw. Therefore, leave the screw out by
approx. 3 mm (Fig. 3.1).
3. Hook the control unit onto the 3 mm pro-
truding screw in the upper mounting hole.
Insert the supplied rubber grommets into
the openings at the rear wall of the hous-
ing and insert the connecting cable through
these openings.
Fasten the housing bottom at the two bot-
tom openings (Fig. 4) rmly to the cabin wall.

Remove the control device cover. In order to do
this loosen the screw at the top of the housing
and pull the housing top upward while swivel-
ling (Fig. 1).

Connecting the sensor cables
You should not install sensor and power supply
lines together, or lead them through the same
feedthrough. This can lead to interferences in
the electronics, such as "uttering" in the re-
lays. If it is necessary to lay the cables down
together, or if the line is longer than 3 m, use a
shielded sensor cable (4 x 0.5 mm²).
Connect the shielding to ground in the control
unit.
Please observe that the following dimensions
relate to the values stipulated during the unit
inspection acc. EN 60335-2-53. The heater sen-
sor must always be installed at the point where
the highest temperatures are to be expected.
Illust. 7-9 give you an overview of the mounting
point of the sensor.

2. Drill a hole to lead the cable through, prefer-
ably through the middle of one of the wood-
en boards.
3. Lead the sensor cable through the drilled
hole and attach it to the sensor line accord-
ing to g. 8.
4. The cables for the temperature sensor (red)
are connected to the sensor circuit board ac-
cording to Fig. 9. Engage the sensor board
into the casing.
5. Lead the sensor cables through the right
cable intake into the control unit. Install
the sensor cables inside the control unit as
shown in Fig. 10. Connect the sensor cables
as shown in Fig. 11. In order to do this, pull
the plug X2 from the circuit board and plug
it back in after the connection.
Installation of the tempera-
ture sensor
1. The temperature sensor should be mounted
on the ceiling in the middle of the cabin. See
g. 7 for details.

6. After completed installation and correct
commissioning of the control unit, the line
for overtemperature protection must be
checked for short-circuits. In order to do this,
disconnect one of the wires of the white ca-
ble in the sensor casing. The respective error
message appears in the display. Reconnect
the wire to make the message disappear.
Attention! Incorrect connection at the con-
nector X2 will cause the fuse F2 to blow (see

Electrical connection
The electrical connection may only be done
by a certied electrician in compliance with
the guidelines of the local utility company
and the VDE.
In general, there should be only one perma-
nent connection to the mains. Furthermore,
equipment should be provided that makes it
possible to disconnect the system on all phases
from the mains with a contact opening width
of minimum 3 mm.
All electrical installations and all connection
lines that are installed inside the cabin must be
suitable for an ambient temperature of at least
170 °C.
The power supply line is run to the control unit
and connected to the power input terminals.
• The cabin lamp must be suitable for the
temperatures expected in the infrared
cabin.
• Lay the connection cable from the control
unit to the lamp through the pre-drilled
hole in the cabin wall, so that the cable
is not visible inside cabin. Make the con-
nections as per connection diagram and
installation guide for the lamp.
• The lamp should be installed as far as pos-
sible from the IR-radiators and may not be
installed within the direct heat radiation
range.
• Make sure to observe the maximum
power load of the light output.
Connecting the cabin lamp
Installation of IR-radiator
• Install the IR-radiator in the cabin as per the
appropriate installation manual.
• Please note that the maximal power of con-
nected IR-radiators per phase may not ex-
ceed 3500 W.
ATTENTION!
Swapping the phase line and neutral line
will damage the control unit and can make
the safety-relevant components fail.
Danger to life!

Once the target temperature has been reached,
the thermometer is displayed as lled.
Energy-saving display
If the unit is not used, it will switch into energy-
saving mode.
A moving time is shown after 5 minutes, simi-
lar to a PC screensaver. The back light for the
display is switched o after an additional 15
minutes.
You can return to the basic standby screen by
pressing any button.
