Introductory information
For your safety
Please follow these safety instructions closely to prevent accidents and
material losses.
If you smell gas
Ho not smoke! o not use naked
flames or cause sparks (e.g. by
switching lights or electrical
appliances on and off).
HOpen windows and doors.
HClose the gas shut-off valve.
HNotify your heating engineer/
installation contractor from outside
the building.
HObserve the safety regulations of
your gas supplier (see gas meter)
and of your heating engineer (see
commissioning/training report).
In an emergency
HImmediately isolate the mains
electrical supply, e.g. by removing
a separate mains fuse or by means
of a mains electrical isolator
(unless you smell gas).
HClose the shut-off valves of the
main fuel lines.
HIn case of fire, use an appropriate
fire extinguisher.
Wor on the equipment
Installation, initial start-up, inspection,
maintenance and repairs must only
be carried out by a competent person
(heating engineer/installation
contractor).
Before working on the equipment/
heating system, isolate the mains
electrical supply (e.g. by removing a
separate mains fuse or by means of a
mains electrical isolator) and safeguard
against unauthorised reconnection.
When using gas as fuel, also close
the shut-off valve and safeguard
against unauthorised re-opening.
Installation of additional components
The installation of additional compo-
nents which have not been tested
together with the boiler can adversely
affect the boiler function.
Our warranty does not cover and we
accept no liability for damage caused
by the installation of such components.
Boiler room conditions
Ho not permit air pollution by
halogenated hydrocarbons (e.āg. as
contained in aerosols, paints,
solvents and cleaning agents).
Ho not use rooms with high levels
of dust.
Ho not use rooms with permanently
high levels of humidity.
HThe room should be frost protected
HMax. ambient temperature 35ĂºC.
HEnsure good ventilation and do not
close or obstruct any vents (where
provided).
Notice of completion
The user of any combustion equipment must notify the local chimney sweep
within four weeks of completion (in Germany).

Start-up/shutdown
Starting the heating system
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.
1. Check the pressure of your
heating system on the pressure
gauge A:
If the needle is below the red
marker, the system pressure is too
low ć in which case, top up with
water or contact your heating
engineer.
2. Open the shut-off valves in the oil
supply pipes (at the oil tank and
filter) or open the gas shut-off
valve.
3. Switch on the mains supply, e.g.
at a separate fuse or a mains
isolator.
4. Switch on the main ON/OFF
switchĂ"8"; standby mode is then
indicated by the green lamp (ON
lamp); shortly after the display will
indicate the boiler temperature
(see page 6).
Your heating system and, if
installed, your remote control unit
are now ready to operate.
5592Ă363ĂGB

Start-up/shutdown
Shutting down the heating system
If you intend shutting down your heating system for a certain time, e.āāg.
during a summer holiday, change to Standby mode (see "Selecting heating
program" on pageĂ10).
Shut down your heating system completely, if it will not be needed for longer
periods of time (several months).
Before 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 measures, e.āāg. protecting
the system against frost or preserving the heating surfaces.
1. Switch off the main ON/OFF
switch "8" .
The green light (ON lamp)
extinguishes.
2. Close the shut-off valves in the oil
supply pipes (at the oil tank and
filter) or the gas shut-off valve,
whichever applies.
3. Isolate the system from the mains
electricity supply, e.g. by
removing a separate fuse or by
means of a mains electrical
isolator.
As the system is now voltage free,
the heating system has no frost
protection.
Please note:
All settings remain intact.

Modifying and scanning time programs
General notes
You can set time programs for central heating, for HW heating (subject to a
HW cylinder being installed) and the HW circulation pump (if installed).
The HW circulation pump ensures that hot water is available at the draw-off
points at short notice.
The time program comprises four time phases, i.e.
Hfor central heating, up to four changes between "Standard room
temperature" and "Reduced room temperature" can be programmed.
HHW heating and HW circulation pump can be activated/deactivated up to
four times per day.
At the factory, phase 1 is set for all weekdays, i.e. in this phase all rooms are
heated at standard room temperature, HW is produced and the HW
circulation pump is activated.
The following keys are allocated to the time programs:
Key Time program for Basic factory setting
ACentral heating Standard room temperature:
from 6.00 to 22.00 hrs
BHW heating On:
5.30 to 22.00 hrs
CHW circulation pump On:
5.30 to 22.00 hrs
You can select identical time programs for all weekdays or individual ones for
each weekday.
Take the response time of your heating system into consideration when
setting the time programs. Select correspondingly earlier start-up and
shutdown times.
