■
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 humidity levels (e.g.
through continuous drying of washing).
Safety instructions
Extractors
Operating appliances that extract air to the outside
(cooker hoods, extractors, air conditioning units, etc.)
can create negative 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 poisoning 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.
Only have installation or replacement work carried out by qualified contractors.

Intended use
Introductory information
The appliance is only intended to be installed and
operated in sealed unvented 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 permissible, system-specific components has been carried out.
Commercial or industrial usage for a purpose other
than heating the building or DHW does not comply with
regulations.
Commissioning
The commissioning and matching of the control unit to
local conditions and building characteristics, as well as
instructing the user in the operation of the system,
must be carried out by your heating contractor.
Any usage beyond this must be approved by the manufacturer for the individual case.
Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibited and results in an exclusion of liability. Incorrect
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).
As the user of new combustion equipment, 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, cleaning).
Your system is preset at the factory
The control unit is preset at the factory to " " for
central heating and DHW heating.
Your heating system is therefore ready for operation:
Central heating
■
The rooms are heated in accordance with the settings on your control unit and room temperature control unit.
■
Your heating contractor can make further settings for
you during commissioning.
You can change any settings individually at any time
to suit your requirements (see chapter "Central heating").
Terminology

Introductory information
Tips on saving energy
Use the adjustment options on the control unit and the
room temperature control unit:
■
Do not overheat your rooms; you can save up to 6 %
on your heating costs for every degree you reduce
your room temperature.
Set your room temperature no higher than 20 °C
(see page 11).
■
Do not set your DHW temperature too high (see
page 12).
■
Select the operating program that meets your current
requirements:
–
In the summer, when you don't want to heat any
rooms but do need DHW, select operating program
" " (see page 12).
–
If you do not want to heat any rooms and require
no hot water for a prolonged period of time, select
operating program " " (see page 9).
Further recommendations:
■
Correct ventilation/airing.
Fully open windows for a short time and close the
thermostatic valves while airing.
■
Close roller shutters (if installed) at dusk.
■
Set thermostatic valves correctly.
■
Never cover radiators or thermostatic valves.
■
Controlled DHW consumption: A shower generally
uses less energy than a full bath.

Cleaning
All equipment can be cleaned with a commercially
available domestic cleaning agent (non-scouring).
Inspection and maintenance
The inspection and maintenance of a heating system
is prescribed by the Energy Saving Ordinance [EnEV Germany] and the DIN 4755, DVGW-TRGI 2008 and
DIN 1988-8 standards.
Regular maintenance ensures trouble-free, energy efficient, environmentally responsible and safe heating.
Your heating system must be serviced by an authorised contractor at least every 2 years. For this, we
strongly advise you to arrange an inspection and maintenance contract with your local heating contractor.
Boiler
Increasing boiler contamination raises the flue gas
temperature and thereby increases energy losses. For
that reason, all boilers should be cleaned annually.
DHW cylinder (if installed)
You can clean the front of the programming unit with a
microfibre cloth.
Potable water filter (if installed)
To maintain high hygienic standards, proceed as follows:
■
Replace filter element on non-back flushing filters
every six months (visual inspection every
two months).
■
On back flushing filters, back flush every
two months.
Standards DIN 1988-8 and EN 806 specify that maintenance and cleaning should be carried out no later
than 2 years after commissioning and as required
thereafter.
Only a qualified heating contractor should clean the
inside of a DHW cylinder and the DHW connections.
If any water treatment equipment (e.g. a sluice or
injection system) is installed in the cold water supply of
the DHW cylinder, ensure this is refilled in good time.
In this connection, observe the manufacturer's instructions.
In addition for Vitocell 100:
We recommend that the correct function of the sacrificial anode is checked annually by your heating contractor.
The function of the sacrificial anode can be checked
without interrupting the system operation. The heating
contractor will check the earth current with an anode
tester.
Safety valve (DHW cylinder)
The safety valve function should be checked every six
months by venting, either by the system user or the
local heating contractor (see the valve manufacturer's
instructions). The valve seat may become contaminated.

Terminology
Constant temperature operation
In constant temperature operation, the heating water is
constantly heated to the selected boiler water temperature.
Operating program
The operating program determines whether you heat
your rooms and DHW, or only heat DHW, or whether
you shut down your heating system and enable frost
protection monitoring.
You can select the following operating programs:
■
" "
The rooms are heated and DHW is provided (winter
mode).
■
" "
DHW is provided but there is no central heating
(summer mode).
■
" "
Frost protection for the boiler and DHW cylinder is
active, no central heating, no DHW heating (standby
mode).
Note
An operating program for central heating without DHW
heating is not available. If rooms are to be heated, hot
water is generally also required (winter mode).
If you still only want central heating, select operating
program " " and set the DHW temperature to 10
°C (see page 12). This means that you will not heat
DHW unnecessarily but the DHW cylinder is protected
against frost.
Heating circuit
Balanced flue operation
The combustion air is drawn from outside the building.
Safety valve
A safety device that must be installed by your heating
contractor in the cold water pipe. The safety valve
opens automatically to prevent excess pressure in the
DHW cylinder.
Set temperature
Default temperature that should be reached, e.g. set
DHW temperature.
Summer mode
Operating program " ".
During the warmer months of the year, i.e. if the rooms
do not have to be heated, you can deactivate heating
mode. The boiler remains operational for DHW heating.
Cylinder loading pump
Circulation pump for heating the DHW in the DHW cylinder.
Drinking water filter
A device that removes solids from the water. The
drinking water filter is installed in the cold water pipe
upstream of the DHW cylinder or the instantaneous
water heater.
A heating circuit is a sealed unvented circuit between
the boiler and radiators, in which the heating water circulates.
Heating circuit pump
Circulation pump for the circulation of the heating
water in the heating circuit.
Actual temperature
Current temperature at the time of the scan; e.g. actual
DHW temperature.
Boiler water temperature
See "Constant temperature operation".
Open flue operation
The combustion air is drawn from the room where the
boiler is installed.
