Dear customer

You have purchased a high-quality technical

device with which you will have years of sauna

fun. This sauna control unit was designed and

inspected according to the current European

safety standards and manufactured at the facto-

ry in accordance with the quality management

standard DIN EN ISO 9001:2000.

This detailed installation and operation manual

has been prepared for your information. Please

observe in particular the important notes and

the information on electrical connection.

Wewishyouexhilaratingrecreationalexperience

and lots of fun with your sauna!

Intended use

This sauna control unit is exclusively intended

for the control of the sauna heater in a sauna

cabin.

Any other use over and above the intended

purpose is not considered as appropriate use!

Compliance of the standard operation, mainte-

nance and repair conditions is also an element

of appropriate use.

The manufacturer cannot be held liable for

deviating, unauthorized alterations and any re-

sulting damages: the initiator of these changes

bears the full risk.

General information

Please check whether the unit has arrived in per-

fect condition. Any transport damages should be

immediately reported to the freight forwarder

delivering the goods or you should contact the

company that shipped the goods.

Please note that you will only be able to achieve

an optimum sauna climate if the cabin with its air

intake and ventilation, the sauna heater and the

control unit are aligned to each other.

Please observe the information and stipulations

made by your sauna supplier.

Sauna heaters heat up your sauna cabin using

heated convective air. Here, fresh air is drawn

in from the air intake which, when heated, rises

upwards (convection) and is then circulated

within the cabin. Part of the used air is pushed

out through the vent in the cabin.This creates a

typical sauna climate which can achieve temper-

atures of approx. 110°C measured directly under

the ceiling of your sauna, dropping in temper-

ature to approx. 30-40°C towards the oor. It is

therefore not unusual to measure temperatures

of 110°C on the temperature sensor hanging

over the heater, whilst the thermometer hanging

on the sauna wall, approx. 20-25 cm under the

cabin ceiling, only indicates 85°C. The bathing

temperature generally lies between 80°C and

90°C in the area of the upper bench when the

temperature is set to maximum.

Please note that the highest temperatures are

always generated over the sauna heater and that

the temperature sensor and the safety limiter

must be mounted there in accordance with the

control unit installation instructions.

When heating up for the first time, you may

notice a slight smell caused by evaporating

lubricants used in production processes. Please

ventilate your cabin before beginning your

sauna bath.

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 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 qualied

technician may 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 bench area of the sauna cabin can be

achieved only if unit is assembled correct-

ly.

• 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

contactor box).

• 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 note the safety and installation

information from the sauna oven manu-

facturer.

• Always heed the specications and in-

structions of the cabin manufacturer, too.

• If control units with remote con-

trol options* are used, protection

against activation when the heater is

covered is required. (e.g. cover protec-

tion Type 1-5 or S-Guard).

*Telecontrol = setting up, controlling or adjusting a

unit by a command that can be given out of view

of the unit by means of transfer media such as tele-

communication, audio technology or bus systems.

(this also includes weekly timers)

Attention!

Dear customer,

according to the valid regulations, the

electrical connection of the sauna heater

and the control box has to be carried out

through the specialist of an authorized

electric shop

We would like to draw your attention that

in case of a warranty claim, you are kindly

requested to present a copy of the invoice

of the executive electric shop.

When designing the cabin ensure that

the external exposed glass surfaces only re-

ach a maximum temperature of 76°C. If ne-

cessary, protective features need to be tted.

Installation of the control unit

Wall installation

The control unit may only be mounted outside

the sauna cabin. It is advisable to select the out-

side wall of the cabin to which the sauna heater

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

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 protru-

ding 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 the-

se openings.

Fasten the housing bottom at the two bot-

tom openings (Fig. 4) rmly to the cabin wall.

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 3m, 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.

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 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.

Install the sauna heater in front of the air intake

according to the manufacturer’s installation in-

structions.

Run the silicone line through the ductwork to

the power unit and connect it to the appropri-

ate 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 inuences. Therefore, use a sui-

table 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 splashproof protected

(IPx4) and resistant to the ambient tempera-

ture.The sauna lamp may be installed at any lo-

cation but never in the vicinity of the rising hot

air of the heater. Use only heat resistant bulbs.
