The commissioning and matching up
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 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).

We recommend you contact your heating contractor if you are planning to start
up a heating system that has not been used for a long period.
1. Check the pressure of your heating
system on the pressure gauge.
Minimum system pressure 0.8
bar.
Notify your heating contractor if the
pressure of the system is too low.
2. Open the gas shut-off valve.
3. Switch ON/OFF switch ON.
Your heating system and room ther-
mostat (if connected) are now
ready for operation.
Shutting down the heating system
Switching the Vitodens OFF with frost protection
If you do not wish to use your boiler for several days you can switch it off. Not at
the fused spur.

Start-up/shutdown
5592 584 GB

Turn both rotary selectors to "0".
Frost protection is now active for the
boiler.
Note
Frost protection for the entire heating
system –see operating instructions
for the room temperature control unit.
Shutting down the heating system
Shut down your heating system completely if it will not be required for longer
periods (several months).
We recommend you contact your heating contractor if you plan to take your
heating system out of use for longer periods. Your heating contractor can then
take any necessary action, subject to requirements, e.g. frost protection or pre-
serving the heating surfaces.
1. Close the main gas shut-off valve
and safeguard against
unauthorised reopening.
2. Switch ON/OFF switch OFF.
The power to the system is now
switched off.
Note that the system is no longer
frost protected.

Switching ON:
Move rotary selector "tr" to the
required heating water temperature.
Note
If a room thermostat is connected,
use it to set the required room tem-
perature (see page 7).
Indicator "r" appears on the display
if central heating is active.
Switching OFF:
Turn rotary selector "rt" to "0".
Domestic hot water
Select the DHW temperature in accordance with your personal requirements (e.
g. for showering).
Switching ON:
Move rotary selector "tw" to the
required DHW temperature.
If DHW heating is active, the indicator
"w" appears on the display.
Switching OFF:
Turn rotary selector "tw" to "0".
Note
If the boiler does not have a DHW
cylinder connected or an integral
instantaneous water heater, turn the
rotary selector "tw" to "0".

clockwise as far as possible (for less
than 3 s) then turn it anticlockwise
again.
"COMFORT" appears on the display.

All devices may 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 Order [EnEV - Germany] and the DIN 4755, DIN 1988-8 and EN
806 standards.
Regular maintenance ensures a trouble-free, energy-efficient and environmen-
tally responsible heating operation. For this, we strongly advise you to arrange
an inspection and maintenance contract with your heating contractor.
Boiler
Increasing boiler contamination raises
the flue gas temperature and thereby
increases energy losses. All boilers
should therefore be cleaned annually.
Logbook
Please ensure that you have a Log-
book supplied with your appliance.
This Logbook should be completed by
your installer to verify that the correct
installation and commissioning proce-
dure was followed.
Failure to complete the Logbook may
result in difficulties should a problem
arise with your appliance during the
guarantee period. This Logbook forms
part of the industry's Benchmark code
of practice for the installation, com-
missioning and servicing of central
heating systems.
All CORGI Registered Installers carry
a CORGI ID card and have a registra-
tion number. Both should be recorded
in your Logbook. You can check your
installer is CORGI registered by call-
ing CORGI on 0870 401 2230.

With the following steps, you can save additional energy:
&Correct ventilation/airing.
&Briefly open windows Afully and at
the same time close the thermo-
static valves B
&Never overheat rooms;
&endeavour to achieve a room tem-
perature of 20 °C; every degree of
room temperature reduction saves
up to 6% of your heating bills.
&Close roller shutters (where
installed) at dusk.
&Set thermostatic valves Bcor-
rectly.
&Never cover radiatorsCor thermo-
static valves B.
&Utilise the setting options offered by
control unit D.
&
&Controlled DHW consumption: A
shower generally uses less energy
than a full bath.
