Introductory information
Initial start−up
The initial start−up and matching of
the control unit to local conditions
and the structural characteristics of
the building must be carried out by
your heating contractor.
As the user of new combustion
equipment, you are obliged to notify
the installation to your local flue gas
inspector (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 heating system is preset at the factory
You may change the factory settings
in accordance with individual
requirements.
Note
All data is saved in case of power
failure.
5592492GB
The control unit is preset at the
factory. Your heating system is
therefore ready for use:
H Between 06:00 and 22:00h, central
heating operates with standard
room temperature.
H Between 05:30 and 22.00h, DHW is
heated (if a DHW cylinder is
installed, DHW will be reheated to
the set temperature), and the DHW
circulation pump is ON (if
connected to the control unit).
H Between 22:00 and 06:00h, central
heating operates with reduced
room temperature (set to 3 ºC,
frost protection).
H Between 22:00 and 05:30h, DHW
cylinder will not be reheated.
H Weekday and time (CET),
summer/winter time changeover is
automatic.

Heating circuit selectionbefore any adjustment and scanning
Your building may be heated by several interdependent heating circuits (e.g.
underfloor heating circuits or radiator circuits).
These are selected at the control unit using keys!, ? or §. Your heating
contractor will label the keys individually.
Heating system with only one heating circuit
Key ! or ? and one of the keysG, L or K are illuminated, and you can

Start−up/shutdown
Heating system start−up
1. Check the pressure of your heating
system on the pressure gauge.
The system pressure is too low if
the indicator points to the area
below the red field. In that case,
top up with water or notify your
local heating contractor.
2. Open the shut−off valves in the oil
supply lines (at the oil tank and
filter) or open the gas shut−off
valve.
3. Switch ON the mains power
supply, e.g. at a separate fuse or a
mains electrical isolator.

Heating system shutdown
If you want to shut down your heating system temporarily, e.g. during a
summer holiday, set the heating circuit to "Standby mode" K (see page14).
Note
The circulation pumps are briefly started every 24hours to prevent them from
seizing up.
Switch your heating system OFF if you do not intend using it.
Before and after you shut down your heating system for longer periods, it
would be advisable to contact your local heating contractor.
Where necessary, your contractor can take certain steps, e.g. protecting the
system against frost.
1. Switch ON/OFF switch"8" OFF
(see page8).
The green lamp (ON indicator)
extinguishes.
2. Close the shut−off valves in the oil
supply lines (at the oil tank and
filter) or close the gas shut−off
valve.
0
3. Switch the mains power supply
OFF, e.g. at a separate fuse or a
mains electrical isolator.
As the system is now voltage free,
the heating system has no frost
protection.

indicated by the flashing red fault indicator.
You can check the fault code on the display and then notify your heating
contractor accordingly. This allows the heating contractor to better prepare
for the service call and may save additional travelling costs.

Fuel oil additives
Fuel oil additives are materials that
can be used to
H improve fuel stability during
storage,
H improve thermal stability of fuel
and
H reduce odour during filling.
!
Bio−fuels
Bio−fuel is made from vegetable oil,
e.g. sunflower or rapeseed oil.
!
Please note
Bio−fuels can lead to damage
on Viessmann oil burners.
Their use is not permissible.
Please note
Fuel oil additives can create
residues and impair the safe
operation of your heating
system.
The use of fuel oil additives
which leave residues is not
acceptable.
Combustion improvers
Combustion improvers are additives
for optimising fuel oil combustion.
Viessmann oil burners do not require
combustion improvers, as these
burners operate with clean and
efficient combustion.
!
Please note
Combustion improvers can
create residues and impair the
safe operation of your heating
system.
The use of combustion
improvers which leave
residues is not acceptable.

Repairs
Cleaning
All devices may be cleaned with a
commercially available domestic
cleaning agent (non−scouring).
Inspection and maintenance
Inspection and maintenance of your heating system is prescribed by the
Energy Savings Order [Germany] and the standards DIN4755, DIN4756,
DIN19888 and EN806 and/or local regulations.
Regular maintenance ensures trouble−free, energy−efficient and
environmentally responsible heating operation. 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.
checked annually by a heating
contractor. The anode function can
be checked without interrupting
system operation. The heating
contractor will check the earth
current with an anode tester.
DHW cylinder
DIN 1988−8 and EN806 prescribe that
maintenance and cleaning should be
carried out no later than two years
after commissioning and thereafter
as necessary.
Only a recognised heating contractor
should clean the inside of a DHW
cylinder and the DHW connections.
Refill any water treatment equipment
(e.g. a lock or injection equipment) in
good time, if such equipment is
installed in the cold water supply of
the DHW cylinder. Observe the
manufacturer’s details.
Safety valve (DHW cylinder)
Check the safety valve function every
six months by venting, or have it
checked by your heating contractor.
The valve seat may become
contaminated (see the valve
manufacturer’s instructions).
48
5592492GB
In addition for Vitocell 100:
We recommend that the correct
function of the sacrificial anode is
DHW filter (where installed)
To maintain high hygienic standards
H on non−back−flushing filters,
replace filter element every
6 months (visual check every
2 months);
H on back−flushing filters, back−flush
every 2 months.
