Activating screed drying
Screed drying
Six different temperature profiles can be set for screed
drying:
Default temperature profiles can be set in
"System
configuration" .
For further details, see "Function description".
Note
Screed drying applies to all connected heating circuits
simultaneously. DHW heating is not possible during
screed drying.
Leak test on balanced flue system (annular gap check)

Combustion air aperture
For balanced flue systems tested together with the
heat generator, there is no requirement for a tightness
test (overpressure test) during commissioning by the
flue gas inspector.
In this case, we recommend that a simple tightness
test is carried out during system commissioning. For
this, check the CO
2
or O
2
concentration in the combus-
tion air at the annular gap of the balanced flue pipe.
If the CO
2
concentration is less than 0.2 % or the O
2
concentration is greater than 20.6 %, the flue pipe is
deemed to be sufficiently gas-tight.
If actual CO
2
values are greater or O
2
values are lower,
then pressure test the flue pipe with a static pressure
of 200 Pa.
