• Installation and operating instruction

Dear customer,

with the purchase of this IR control unit, you have

opted for a superior quality and an innovative

electronic device which has been developed

and manufactured according to the highest

standards and norms.

Please read the guidelines in these instructions

carefully so that you can familiarise yourself

quickly and easily with the unit.

General information

The IR control unit is designed for power supply

230 V 1N 50 Hz AC and shall be protected with a

separate 16 A fuse.

The installation and connection of the sauna fa-

cilities and other electrical operating equipment

may only be carried out by a specialist from an

authorised specialist electrical company; here

VDE 0100 Part 703/2006-2 must be observed.

Please read the following installation and operat-

ing instructions through carefully so that your IR

system can be operated without malfunctions.

Please also follow the information and instruc-

tions provided by the IR cabin manufacturer.

General safety precautions

• The unit may only be used for its intended

purpose as a control for IR radiators or IR heat-

ing foils up to max. 3.5 kW.

• The electrical installation may only be per-

formed by an authorized electrician.

• You must comply with the regulations of your

utility company as well as the standard VDE-

guidelines (DIN VDE 0100).

• CAUTION! Danger of death, never carry out

repairs and installations yourself. Only a

qualied technician may remove the housing

cover.

• Caution: The control power element may not

be installed in enclosed switching cabinets or

be enclosed in wooden panelling!

• The unit may only be used for its intended

purpose as a control for IR radiant heaters.

• The system must be disconnected at all poles

from the mains during all installation and re-

pair work, meaning that you must switch o

all fuses or the main switch.

• Follow the safety and installation information

provided by the manufacturer.

• This unit is not intended for use by persons

(including children) with restricted physi-

cal, sensory or mental capacity or by per-

sons without the necessary experience and/

or knowledge unless they are supervised by

someone responsible for their safety or re-

ceive instructions from them on how to use

the unit.

• Children are to be supervised in order to en-

sure that they do not play with this device.

• Only IR radiators acc. DIN 60335 or IR

heating foils with integrated overheating pro-

tection (140°C) may be connected.

• Follow the safety and installation information

provided by the IR radiant heater manufac-

turer.

Installation

Relay box

The relay box may only be installed outside the

cabin. It is advisable to select the outside wall

of the cabin or the cabin ceiling for the instal-

lation. If ductwork is provided for the electri-

cal installations then the position of the power

switchgear is predetermined by that. Please fol-

low the instructions for installation:

1. Remove the cover of the power ele-

ment. To do this, push the retaining tang

to the inside with a at screwdriver and

pivot the housing top upwards (Fig. 1).

The 5 mm diameter boreholes for the sup-

plied wood screws 4 x 20 mm are drilled ac-

cording to the dimensions shown in Fig. 2.

2. Insert one of the wood screws into the top

center hole. The power element is hooked

onto this screw. Therefore, leave the screw

out by ca. 3 mm (Fig. 3).

3. Hook the power element to the 3 mm pro-

truding screw in the upper mounting hole

Insert the supplied rubber grommet

into the openings at the rear wall of

the housing and insert the connect-

ing cable through these openings.

Fasten the bottom section of the housing

rmly to the cabin wall or cabin ceiling by

inserting the screws into the two lower bore-

holes (Fig. 4).

Installation

Control panel

The control panel should be mounted outside

the cabin. If the control panel is mounted in-

side the cabin it may not be placed in the direct

range of the IR-beam and the maximum room

temperature may not exceed 60°C. If ductwork

is already provided for electrical installations

then the position of the control panel is prede-

termined by that. The installation is done into

the cabin wall. Please follow the instructions for

installation:

The mounting position must be specied rst

for installation outside the cabin.

Inside the cabin select a mounting position

that is preferably underneath an IR-beam.

Insulation control panel cable

Lay the connection cable from the control pan-

el to the relay box.

The connection cablemay only be laid between

the insulation and the outside wall of the cabin

(Fig. 7). The insulation must be designed for

max. outside temperature of 75 °C.

Mount the control panel in the wall opening

and x it with the 4 screws enclosed.

Finally glue the self-adhesive decorative strips

into the horizontal grooves of the control panel.

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.

Mains connection is carried out using a Schuko

type plug, to be mounted by the customer, to

a separate Schuko type socket with a 16A fuse.

Because of the higher starting current has the

unit to be fused by a 16A circuit breaker with K

characteristic.

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.

Lay the connection cables (max. 5 m length)

from the separate IR radiators to the relay box

and connect according to the connection dia-

gram.

If more than one IR-radiator is to be connected

per heating circuit, the respective connection

lines fromthese radiators must be connected

in junction boxes provided by the customer

outside the power unit. Only one cable line may

be connected to the terminals of each power

output circuits.

Lay the connection cable from the control ele-

ment to the power switchgear and produce the

plug connections according to the connection

diagram.

Adapting the control to the installed

components.

On the circuit board of the IR control power unit

you will nd a pin block for three jumpers

The type of emitters used is set using the jump-

ers 1 + 2.

IR radiant heater

If exclusively IR radiant heaters are

installed, both jumpers remain open

IR heating foil

If IR heating foils are installed, Jump-

er 1 is connected and Jumper 2

remains open.

A radiant heater for the legs can also

be installed

IR radiant heater & IR heating foil

If both IR radiant heaters - except for

the radiant heater for legs - and IR

heating foils are installed, Jumper 2

is connected and Jumper 1 remains

open.

You can set the maximum heating

time with Jumper 3

Maximum heating time 99 minutes

Jumper 3 open

Maximum heating time 12 hours

Jumper 3 closed

Notice: by connection of IR heating foils the

optional 2nd sensor (surface sensor for heat-

ing foils) shall be connection and activated

through the jumper setting.

Connecting the sensor cable

You should not draw sensor and power supply

cables together or lead them through the same

duct. This can lead to interferences in the elec-

tronics, such as "uttering" in the relays. If it is

necessary to lay the cables down together, or if

the sensor line is longer than 3m, use a shielded

sensor cable (2 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 room tem-

perature sensor must always be mounted on

the ceiling in the centre of the cabin. The fol-

lowing Figs. give you an overview of the instal-

lation point for the sensor.

Installation of the op-

tional heating foil sensor

Installation location:

The heating foil sensor shall be mounted in the

area of the overheating protection of the small-

est heating foil installed and shall be relaibly

xed with a strain safeguard.

CAUTION! Measurement value falsica-

tion!

If the heating foil sensor is not directly mounted

onto the IR heating foil, the measurement val-

ues will be falsied. Therefore place the heating

foil sensor directly onto the heating foil.

Only mount the heating foil sensor when

using IR heating foils with integrated overheat-

ing protection.

• Mount the sensor directly between the heat-

ing foil and the insulation.
