Dear customer,

with purchase of this sauna control unit you

opted for a superior quality, high-tech elec-

tronic device which was developed and ma-

nufactured to meet the highest standards of

quality and safety.

Please note that an optimal interaction of

sauna cabin, sauna oven and sauna control

unit is mandatory for a pleasant sauna cli-

mate in your cabin.

With this sauna control unit you can operate

your sauna heater and thanks to the indivi-

dual programming settings you will surely

soon ﬁnd the setting that suits you best.

Perception in the sauna is very subjective,

therefore it really requires your own prefe-

rence, or that of your family to ﬁnd the most

suitable settings.

By default the ﬁnnish sauna is preset to

95°C. For steam operation the values are

set to 60°C and 60% humidity.

The following operation instructions describe

how to pre-select „your“ climate in the cabin.

Read these instructions carefully, so that you

quickly and easily ﬁnd your way though the

programming process.

Please note the variation in temperatures in

the cabin while sauna bathing. The hottest

area is directly under the cabin ceiling, whe-

reas there is a steady temperature gradient

towards the ﬂoor of the cabin. Inversely, the

relative humidity is lowest directly under the

cabin ceiling and the highest on the cabin

ﬂoor.

For safety reasons the temperature sensor

with the overheat limiter is located on the ca-

bin ceiling above the oven, since this is the

hottest area in the cabin.

Therefore there will always be temperature

variations between the temperature sensor

of the control unit and the thermometer in

the cabin.

General information concerning sauna bathing

For the cabin light use only light bulbs. Do

not use ﬂuorescent lamps, energy saving

lamps and gas discharge lamps.

For example, when pre-setting the cabin

temperature to 100°C, the thermometer in-

side the cabin may easily show 85°C - 90°C.

This complies with the typical climate inside

the cabin.

Always observe hygiene. Always use hand-

or bathing towels, to avoid getting perspirati-

on on the wood.

To protect your cabin from possible dama-

ges due to steam operation, we recommend

reheating or drying the cabin after every

steam bath.

In addition, a fan can help to dissipate used

humid air in badly ventilated areas.

To avoid the perception of draft, you should

avoid using any ventilation system while

sauna bathing. It should only be used if re-

commended by the cabin manufacturer

Always make sure no objects are

located on the sauna oven before

starting the heating cycle.

General safety precautions

• his device has not been designed for being

used by persons (including children) that

are physically or mentally handicapped

or have sensory disabilities. Moreover, it

is not allowed to use this device without

sufﬁcient experience and/or knowledge,

unless these persons will be supervised

by persons responsible for their security

or in case they have been instructed how

to use this device.

• 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 ca-

binet or behind a wooden panelling!

• The electrical installation may be done

only by a qualiﬁed electrical technician.

• You must comply with the regulations of

your power supply company and applica-

ble VDE regulations (DIN VDE 0100).

• WARNING: Never attempt repairs

or installations yourself, as this could

result in serious injury or death. Only a

qualiﬁed technician may remove the hou-

sing 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 tempera-

ture setting. The temperature can be held

within operating parameters and a mini-

mal temperature gradient inside the bench

area of the sauna cabin can be achieved

only if unit is assembled correctly.

• The device may only be used as intended

as a control unit for sauna ovens up to 9

kW. (Up to 36 kW when combined with a

breaking capacitor).

• Completely disconnect the control unit

from the electrical circuit, i.e. ﬂip all circuit

breakers or the main circuit breaker during

each installation or repair.

• Please note the safety and installation in-

formation from the sauna oven manufac-

turer.

• Always heed the speciﬁcations and in-

structions of the cabin manufacturer, too.

Attention!

Dear customer,

according to the valid regulations, the

electrical connection of the sauna hea-

ter and the control box has to be carried

out through the specialist of an authori-

zed electric shop

We would like to mention to the fact

that in case of a warrenty claim, you

are kindly requested to present a copy

of the invoice of the executive electric

shop.

When using control units that offer the

possibility of external access (GSM-module,

remote button, etc.) or time-delayed swit-

ching (preselection time, weekly timer, or

similar) a trigger guard with covered heating

unit is required. (cover protection type 1-5 or

S-Guard).

Installation of the control unit

Wall mount ﬁxture

The control unit may only be mounted outside

the cabin. It is advisable to select the outside

wall of the cabin to which the sauna heater

is ﬁxed from the inside as mounting position.

If ductwork is already provided for electrical

installations then the position of the control

unit is predetermined by that. Please follow

the instructions for installation:

Fig. 1

1.The 3 mm diameter boreholes for the sup-

plied wood screws 4 x 20 mm are drilled

according to the dimensions shown in Fig.

3 + 3.1.

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. 3.2).

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

housing and insert the connecting cable

through these openings.

Fasten the housing bottom at the two bot-

tom openings (Fig. 4) ﬁrmly to the cabin

wall.

Connecting the sensor cables

You should not install sensor and power sup-

ply lines together, or lead them through the

same feedthrough. This can lead to interfer-

ences in the electronics, such as "ﬂuttering"

in the relays. If it is necessary to lay the ca-

bles down together, or if the line is longer

than 3m, use a shielded sensor cable (4 x

0.5 mm²).

Connect the shielding to ground in the con-

trol unit.

Please observe that the following dimen-

sions relate to the values stipulated during

the unit inspection acc. EN 60335-2-53. The

heater sensor 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.

1. Mount the oven sensor in cabins up to 2

x 2m according to Illust. 7 and 8, in larger

cabins according to Illust. 7 and 9.

Electrical connection

The electrical connection may only be

done by a certiﬁed electrician in compli-

ance with the guidelines of the local utility

company and the VDE.

In general, there may be only one ﬁxed con-

nection to the network; therefore equipment

should be provided that makes it possible

to disconnect the system with all poles from

the network 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 load con-

trol unit and connected to the power input

terminals.

Install the sauna heater and the vaporizer in

front of the air intake according to the manu-

facturer’s installation instructions.

Run the silicone line through the ductwork

to the power unit and connect it to the ap-

propriate terminals as directed in the wiring

diagram.

Note: In case there is no ductwork available

drill a hole next to the air intake opening and

run the heater line through this hole to the

outside and to the appropriate terminals in

the control unit. The silicone line must be

buried to protect it from outside inﬂuences.

Therefore, use a suitable cable-duct or a

PVC-pipe through which you can run the line

up to the power unit.

Connecting the

sauna heater

The sauna lamp must be weatherproof pro-

tected (IPx4) and resistant to the ambient tem-

perature. The sauna lamp may be installed

at any location but never in the vicinity of the

rising hot air of the heater.

Connecting the sauna lamp

To connect the vaporizer, use silicone con-

necting lines 4 x 1,5 mm² as well.

Warning: When connecting

the vaporizer make sure it is

correctly attached to the water bath

(WB) and low water shutoff (WM). If

you switch these connections, you dis-

able the water deﬁciency function and

bypass the thermostat. As a result, the

vaporizer will overheat.

Risk of ﬁre!

Connecting the vaporizer

The control unit can detect water deﬁcit if

there is a zero-potential feed at the WM-input.

Connecting a fan

The fan must be weatherproof protected

(IPx4) and resistant to the ambient tempera-

ture.

The fan can be mounted at any point, but

never near to rising hot air from the heater

and as far as possible from the installation

position of the IR lamp (may not be in the

direct beam).
