rial losses.

Safety instructions explained

Danger

This symbol warns against the

risk of injury.

!Please note

This symbol warns against the

risk of material losses and envi-

ronmental pollution.

Note

Details identified by the word "Note" con-

tain additional information.

Target group

These operating instructions are

designed for heating system users.

This appliance can also be operated by

children of 8 years and older, as well as

by individuals with reduced physical,

sensory or mental faculties or those lack-

ing in experience and knowledge, provi-

ded such individuals are being super-

vised or have been instructed in the safe

use of this appliance as well as in any

risks arising from it.

!Please note

Supervise children in the proxim-

ity of the appliance.

■ Never permit children to play

with the appliance.

■ Cleaning and maintenance

must not be carried out by

unsupervised children.

Appliance connection

■ The appliance may only be connected

and commissioned by authorised con-

tractors.

■ Only operate the appliance with suita-

ble fuels.

■ Observe the specified electrical con-

nection requirements.

■ Modifications to the existing installa-

tion may only be carried out by author-

ised contractors.

Danger

Incorrectly executed work on the

heating system can lead to life

threatening accidents.

Work on electrical equipment

must only be carried out by a

qualified electrician.

Work on the appliance

■ All settings and work on the appliance

must be carried out as specified in

these operating instructions.

Further work on the appliance may

only be carried out by authorised con-

tractors.

■ Never change or remove attachments

or fitted accessories.

Safety instructions

For your safety

5549 811 GB

If you smell flue gas

Danger

Flue gas can lead to life threat-

ening poisoning.

■ Shut down the heating system.

■ Ventilate the installation site.

■ Close all doors in the living

space.

In case of fire

Danger

Fire presents a risk of burns and

explosion.

■ Shut down the heating system.

■ Use a tested fire extinguisher,

class ABC.

What to do if the heating system

develops a fault

Danger

Fault messages indicate faults in

the heating system. If faults are

not rectified, they can have life

threatening consequences.

Do not acknowledge fault mes-

sages several times in quick suc-

cession. Inform your heating con-

tractor so the cause can be ana-

lysed and the fault rectified.

Conditions for siting

Danger

Sealed vents result in a lack of

combustion air. This leads to

incomplete combustion and the

formation of life threatening car-

bon monoxide.

Never cover or close existing

vents.

Do not make any subsequent

modifications to the building

characteristics that could affect

safe operation (e.g. cable/pipe-

work routing, cladding or parti-

tions).

Danger

Easily flammable liquids and

materials (e.g. naphtha, solvents,

cleaning agents, paints or paper)

can cause deflagration and fire.

Never store or use such materials

in the installation room or in direct

proximity to the heating system.

!Please note

Incorrect ambient conditions can

lead to heating system damage

and can put safe operation at

risk.

■ Ensure ambient temperatures

are above 0 °C and below

35 °C.

■ Prevent air contamination by

halogenated hydrocarbons

(e.g. as contained in paints,

solvents or cleaning fluids) and

excessive dust (e.g. through

grinding/polishing work).

■ Avoid continuously high humid-

ity levels (e.g. through continu-

ous drying of washing).

Safety instructions

For your safety (cont.)

5549 811 GB

Extractors

The operation of appliances that extract

air to the outside (cooker hoods, extrac-

tors, air conditioning units, etc.) can cre-

ate vacuum pressure. If the boiler is

operated at the same time, this can lead

to reverse flow of the flue gas.

Danger

The simultaneous operation of

the boiler and appliances that

extract air to the outside can

result in life threatening poison-

ing due to reverse flow of the flue

gas.

Take suitable steps to ensure an

adequate supply of combustion

air. If necessary, contact your

heating contractor.

Auxiliary components, spare and

wearing parts

!Please note

Components not tested with the

heating system may damage the

system or affect its function.

Have all installation or replace-

ment work carried out exclusively

by qualified contractors.

The appliance is only intended to be

installed and operated in sealed unven-

ted heating systems that comply with

EN 12828, with due attention paid to the

associated installation, service and

operating instructions. It is only designed

for the heating of heating water that is of

potable water quality.

Intended use presupposes that a fixed

installation in conjunction with permissi-

ble, system-specific components has

been carried out.

Commercial or industrial usage for a pur-

pose other than heating the building or

DHW shall be deemed inappropriate.

Any usage beyond this must be

approved by the manufacturer in each

individual case.

Incorrect usage or operation of the appli-

ance (e.g. the appliance being operated

for longer periods when open) is prohibi-

ted and will result in an exclusion of lia-

bility. Incorrect usage also occurs if the

components in the heating system are

modified from their intended use (e.g. if

the flue gas and ventilation air paths are

sealed) or if other fuels than those inten-

ded for this appliance are used.

Commissioning

The commissioning and matching up of

the control unit to local conditions and

the structural characteristics of the build-

ing must be carried out by your heating

contractor.

Service instructions

As the user of new combustion equip-

ment, you may be obliged to notify your

local flue gas inspector of the installation

[check local regulations]. Your local flue

gas inspector (where applicable) will

also provide you with information on

additional activities concerning your

combustion equipment (such as regular

testing, cleaning, etc.).

Prepare and carry out the emissions

tests according to 1st BImSchV:

Service instructions

Introductory information

Intended use

5549 811 GB

Your boiler's control unit is set at the fac-

tory.

■ The heating circuits are set to the

"Heating" operating program.

■ The domestic hot water heating is set

to the "DHW" operating program.

Your heating system is therefore ready

for operation:

Central heating

■ From 06:00 to 22:00 h your rooms are

heated to 22 °C "Set room temp"

(standard heating mode).

■ From 22:00 to 06:00 h your rooms are

heated with "Set red room temp"

(room temperature for reduced heat-

ing mode, night setback).

■ Your heating contractor can make fur-

ther settings for you during commis-

sioning.

You can change any settings at any

time to suit your individual require-

ments (see from page 22).

DHW heating

■ DHW is heated to 60 °C "Set DHW

temperature" every day from 00:00

to 24:00 h.

■ Your heating contractor can make fur-

ther settings for you during commis-

sioning.

You can change any settings at any

time to suit your individual require-

ments (see from page 35).

Frost protection

■ Your boiler, DHW cylinder and heating

water buffer cylinder are protected

against frost.

Wintertime/summertime changeover

■ This changeover is automatic.

Time and date

■ The day and time were set by your

heating contractor during commission-

ing.

Power failure

■ All data is retained if there is a power

failure.

Introductory information

Your system is preset at the factory

5549 811 GB

The appendix contains a chapter entitled

"Terminology" to provide you with a bet-

ter understanding of the functions of your

boiler.

Energy saving tips

Use the adjustment options offered by

your boiler control unit:

■ For central heating, select the operat-

ing program that meets your current

requirements:

– For short periods of absence (a few

hours e.g. shopping trips), select

"Economy mode" (see page 32).

As long as economy mode is activa-

ted, the room temperature is

reduced.

– If you are going away, select the

"Holiday program" (see

page 33).

The operating program for central

heating is automatically set to

"Standby mode" while the holiday

program is active.

– If, for an extended period, you do not

want to heat the rooms and you do

not require DHW, select the

"Standby mode" operating pro-

gram for the relevant heating circuits

and for DHW.

– See page 24 for the relevant

heating circuits

– See page 35 for DHW heating

■ Never set the DHW cylinder tempera-

ture excessively high (see page 35).

Contact your heating contractor for addi-

tional energy saving functions offered by

the control unit for your boiler.

For recommendations for energy saving,

see page 67.
