8 Adapting the unit to the heating installation
▶
If you are unable to remedy the fault, contact the gas
supply company.
▶
Close the gas isolator cock.
7.13.2 Checking the CO₂ content
Caution.
Risk of operating faults caused by the
corruption of the measured values during
the calibration.
Operating the product with the front casing
open or not completely installed, or with the
flue pipe open, may negatively influence the
calibration of the gas-air mixture.
▶
During the calibration and when measur-
ing the CO₂ content, you must operate the
product with the front casing installed and
closed, and with the flue pipe completely
installed.
1.
Start up the product.
Note
Since the combustion can be continuously
monitored by the product, you do not need to
check the combustion.
2.
Press
and
at the same time to activate the max-
imum output operation.
▽
If S.85 is displayed, the circulation must be
increased in the heating system.
◁
The display shows Chimney sweep and S.93 at the
same time.
◁
The product runs through a calibration process on
the flue gas installation and the gas quality.
3.
Wait until the calibration process has taken place.
◁
After the calibration procedure ends, the display
shows Chimney sweep and S.04 at the same time.
4.
Now measure the CO₂ content at the flue gas analysis
point.
◁
The product restarts the measuring programme after
the burner has been operating for five minutes so
that it can take heating effects into consideration.
◁
The combustion automatically optimises itself. CO₂
content of 8.0 to 10.5 vol.% natural gas) and of 9.0
to 11.8 vol.% (liquid gas) can be measured.
Note
After initial start-up or starting the check pro-
gramme P.04, depending on the heating par-
tial load that is set and the existing heat con-
sumption by the heating installation, it may
be the case that the product runs through the
measuring programme several times. During
the calibration process, no flue gas analysis
is possible.

Checking leak-tightness
▶
Check the gas pipe, the heating circuit and the domestic
hot water circuit for leak-tightness.
▶
Check that the air/flue pipe has been installed correctly.
Conditions: Room-sealed operation
▶
Check whether the vacuum chamber has been closed
tightly.
7.14.1 Checking the heating mode
1.
Make sure that there is a heat requirement.
2.
Call up Live monitor.
◁
If the product is working correctly, the display shows
S.04.
7.14.2 Checking the hot water generation
1.
Open a hot water valve all the way.
2.
Call up the Live Monitor.
◁
If hot water generation is working correctly, the
display shows S.24.

Adapting the unit to the heating
installation
To reset the most important system parameters, use the
Appliance config. menu item.
Menu → Installer level → Appliance config.
Or manually relaunch the installation assistant.
Menu → Installer level → Start inst. assistant
8.1
Calling up diagnostics codes
The settings options for more complex systems can be found
in the Diagnostics menu.
Menu → Installer level → Diagnostics menu
Overview of diagnostics codes (→ Page 33)
You can use the parameters that are marked as adjustable
in the overview of diagnostics codes to adapt the product to
the heating installation and the needs of the customer.
8.2
Burner anti-cycling time
To prevent frequent switching on and off of the burner and
thus prevent energy losses, an electronic restart lockout
is activated for a specific period each time the burner is
switched off. The burner anti-cycling time is only active
for the heating mode. Hot water handling during a burner
anti-cycling time does not affect the time function element
(default setting: 20 mins).
8.2.1
Setting the burner anti-cycling time
Navigate to Menu → Installer level → Diagnostics
1.
menu → D.002 Max. anti-cycl. time: Heating and con-
firm by pressing
2.
Set the burner anti-cycling time and confirm by pressing
