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.

Installation room conditions

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.)

5592 682 GB

Extractors

Operating appliances that extract air to

the outside (cooker hoods, extractors, air

conditioning units, etc.) can create neg-

ative 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 it or

affect its functions.

Have installation or replacement

work only carried out by qualified

contractors.

5592 682 GB

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 water that is of potable

water quality.

Intended usage 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 does not comply with regulations.

Any usage beyond this must be

approved by the manufacturer for the

individual case.

Incorrect usage or operation of the appli-

ance (e.g. the appliance being opened

by the system user) is prohibited and

results in an exclusion of liability. Incor-

rect usage also occurs if the components

in the heating system are modified from

their intended function (e.g. if the flue

gas and ventilation air paths are

sealed).

Commissioning

The commissioning and matching of the

control unit to local conditions and build-

ing characteristics, as well as instructing

the user in the operation of the system,

must be carried out by your heating con-

tractor.

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 will also inform you [where

appropriate] about work he may be

required to carry out on your combustion

equipment (e.g. regular checks, clean-

ing).

Terminology

To provide you with a better understand-

ing of the functions of your Vitotronic

control unit, some terminology is

explained.

The terms are marked as follows:

Introductory information

Intended use

5592 682 GB

Further information can be found

in chapter "Terminology" in the Ap-

pendix.

Your system has been preset

Your heating system is preset at the fac-

tory and is therefore ready for opera-

tion:

Central heating

■ Between 06:00 and 22:00 h, the

rooms are heated to 20 °C "Set room

temperature" (standard heating

mode).

■ Between 22:00 and 06:00 h, the

rooms are heated to 3 °C "Set

reduced room temp" (reduced room

temperature, frost protection).

DHW heating

■ Between 05:30 and 22:00 h, the DHW

is heated to 50 °C "Set DHW temper-

ature". Any installed DHW circulation

pump is switched on.

■ Between 22:00 and 05:30 h, the DHW

cylinder is not reheated. Any installed

DHW circulation pump is switched off.

Note

If DHW heating began before 22:00 h,

it is stopped.

Frost protection

■ Your boiler and DHW cylinder are pro-

tected against frost.

Wintertime/summertime changeover

■ This changeover is automatic.

Date and time

■ The date and time were set by your

heating contractor.

Your heating contractor can make fur-

ther settings for you during commission-

ing.

You can change the settings at any time

to suit your individual requirements.

Power failure

All settings are saved if there is a power

failure.

If the heating system has been shut

down for a prolonged period, reset the

date and time.

Introductory information

Terminology (cont.)

5592 682 GB

Central heating

■Standard room temperature ("Set

room temperature", see page 25):

Never overheat your home. Every

degree of room temperature reduction

saves up to 6 % on your heating bills.

Never set your standard room temper-

ature higher than 20 °C.

■Time program (see page 26):

Heat your rooms to the standard room

temperature during the day and the

reduced temperature at night. Set the

time program for this.

■Operating program:

If you do not require central heating,

select one of the following operating

programs:

–"Only DHW" (see page 31):

If you require no heating for your

home in summer, but you need hot

water.

–"Standby mode" (see page 23):

If you don't need to heat your home

and don't need hot water for long

periods.

■Short absence (see page 29):

Reduce the room temperature if you

are going shopping, for example. For

this, select "Economy mode".

■Holidays (see page 30):

If you are going away, select the "Hol-

iday program":

The room temperature will be reduced,

and DHW heating will be turned off.

■Ventilation:

Close the thermostatic valves to ven-

tilate. Open the windows fully for a

brief time.

■Roller shutters:

Close roller shutters (where installed)

at dusk.

■Thermostatic valves:

Ensure that thermostatic valves are

properly set.

■Radiators:

Never cover radiators or thermostatic

valves.

DHW heating

■DHW circulation pump (see

page 32):

Only activate the DHW circulation

pump for periods in which DHW is reg-

ularly drawn off. Set the time program

for this.

■DHW consumption:

Consider showering instead of running

a bath. A shower generally uses less

energy than a full bath.

For additional energy saving functions of

the Vitotronic control unit, please contact

your heating contractor.
