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 perform
on your combustion equipment (e.g.
regular checks, cleaning).
Your system is preset at the factory
The control unit is preset at the fac-
tory for standard operation. Your heat-
ing system is therefore ready for use:
&Between 6:00 and 22:00 h the sys-
tem provides central heating with
standard room temperature.
&DHW will be heated between 5:30
and 22:00 h. DHW will be heated to
the set temperature subject to a
DHW cylinder being installed. The
DHW circulation pump is switched
ON (if connected to the control unit).
&Between 22:00 and 06:00 h the
system provides central heating
with the reduced room temperature
(set to 3 °C, frost protection).
&Between 22:00 and 05:30 h the
DHW cylinder temperature will not
be boosted. The DHW circulation
pump is switched OFF (if connected
to the control unit).
&The system automatically changes
over between summer and winter
time.
You may change the factory settings
in accordance with personal require-
ments.

All data is saved in case of power fail-

at pressure gauge A: The system
pressure is too low if the indicator
points to the area below 1.0 bar. In
that case, top up with water or
notify your local heating contractor.
2. Foropenflueoperation:
Check whether the ventilation aper-
tures in the installation room are

Open gas shut-off valve B.
For Vitoladens:
Open the shut-off valves in the oil

Start-up/shutdown
5592 545 GB

If, temporarily, you have no need for your heating system, e.g. during a summer
holiday, switch all heating circuits to "Standby mode"K(see page 14).
Note
The circulation pumps are briefly started every 24 hours to prevent them from
seizing up.
If you do not want to use your heating system, you can shut it down.
We recommend you contact your local heating contractor before and after you
shut down your heating system for longer periods.
Your contractor can then take any necessary actions, subject to requirements,
e.g. for frost protection of the system or to preserve the heating surfaces.
1. SwitchthemainON/OFFswitch
"8" OFF; the green indicator (ON
indicator) will extinguish.
2. Close the shut-off valves in the oil
supply lines (at the oil tank and fil-
ter) or the gas shut-off valve.
3. Isolate the system from its main
power supply, e.g. at a separate
MCB/fuse or a main isolator.
