Measuring and setting flue gas values
Note
Use a flue gas analyser that can measure CO and
NOx or NO values. Analysers that can only oper-
ate in a lean range (excess air) are not suitable for
this. Analysers with chemical measurement cells
must be compensated for H2.
1.
If required, close the side panel of the product.
2.
Start the product via the motor switch.
3.
Connect a laptop that has the service software installed
on it to the diagnostics interface on the rear of the
product.
4.
Start the service software.
5.
In the menu for the service software, select the flue gas
test (Settings
→
Flue gas setting).
6.
Start initialisation.
7.
Set the corresponding emissions for the four setting
points by changing the lambda target values:
–
For each speed, set two setting points in order to
reduce the setting time.
–
Use a measuring programme with the specifications
5 minutes rinsing, 5 minutes stabilising, 5 minutes
measuring. The measuring programme should gen-
erate an average value every second over a period
of five minutes.
–
Change the lambda target value for the presetting
in large steps by 0.010, for example, and in small
steps by 0.002, for example.
Note
Lambda limit values are determined during
the measurement. These limit values are re-
quired for calculating the lambda target val-
ues and they must be carefully determined.
The deviation from NOx-160 ppm must be a
maximum of
±
20%, the deviation from CO-
1000 ppm must be a maximum of
±
10%.
8.
Start up the two checkpoints and ensure that the NOx
value is
≤
160 ppm and the CO value is
≤
332 ppm dur-
ing start-up.
6.4
Checking the product
1.
Use leak detection spray to check the gas pipe, flue
system, heating installation and domestic hot water
pipes for leaks.
2.
Check that the air/flue pipe has been installed without
any problems.
3.
Ensure that the electronics boxes and side panels are
properly closed.

Handing over to the end user
▶
Explain to the end user how the safety devices work and
where they are located.
▶
Inform the end user how to handle the product.
▶
Draw attention to the safety information that the end user
must follow.
▶
Inform the end user that they must have the product
maintained in accordance with the specified intervals.
▶
Inform the end user about measures taken to guarantee
the combustion air supply and flue system, and instruct
them that they must not make any changes to the com-
bustion air supply and flue system.
▶
Explain to the end user how to check the water
level/filling pressure of the installation.
▶
Explain to the end user how to fill or purge the heating
installation when required.
▶
Explain to the end user how to set temperatures, controls
and thermostatic valves (economically).
▶
Show the end user how to switch off the product via the
all-pole joint point in the event of emergency.
▶
Pass all of the instructions and documentation for the
product to the end user for safe-keeping. Tell the end
user that the instructions must be stored close to the
product.

Operation
The product has two operating levels:
–
The end user level
–
The installer level
The operating concept and the reading and setting options of
the end user level are described in the operating instructions.
You can find an overview of the installer level's menu struc-
ture in the appendix.

Troubleshooting
9.1
Faults and warnings
Faults and abnormal operating modes are displayed via
faults (
E...
) or warnings (
W...
).
If a fault occurs, the display shows
E...
and a 20-digit fault
code.
