6.3.8 Manual setting of the pump speed regulation
With certain output stages of the speed-regulated solar operating
pump P
S
noise problems can sometimes arise. The current
output of the selected stage is displayed in the bottom line [Flow
rate] in the operating display (see fig. 6-6) as a percentage.
Ɣ
Make a note of the problematic output stage.
Ɣ
Using the menu path: Navigate [choice 2/2] -> [System] ->
[Modulation] to [Level] (see fig. 6-7).
Here, up to 10 speed ranges can be disabled. Next to the ref-
erence number of the output stage (starting with 01 for the lowest
output) and the operating status, the output of the relevant stage
is displayed as a percentage under [performance].
Ɣ
Set noise-intensive stage under the parameter [active] to [no].
Î
The stage is skipped when the solar operating pump P
S
is
activated. Make a note of the problematic output stage It
can be cancelled again by setting the parameter [active]
to [yes] or by the total reset function.
6.3.9 Correction values for measuring points
If the measured value of a sensor deviates from the real value, it
can be adjusted using a correction value.
Ɣ
Using the menu path: [choice 2/2] -> [System] -> [Correction
values] select the correction parameter (see fig. 6-7) and
change in accordance with tab. 6-4.

6.3.10 Cylinder temperature sensor
This contact controls an external heat generator in such a way
that under favourable weather conditions, the storage cylinder is
not heated by the external source. The connection cable offered
as an accessory BSKK (
16 41 10
) is required. If the solar
system reaches a momentary output, adjustable by the heating
expert (menu path: [choice 1/2] -> [Parameter choice] -> [P min])
or if the storage tank has heated up to the adjustable minimum
storage tank temperature set by the heating expert (operating pa-
rameter [TS min] see tab. 6-5), the burner is deactivated via a
contact, for example. The parameter setting for the burner
blocking contact is described in fig. 6-7.
The parameter [time VBSK] makes it possible to set a delay in the
switching timing for the burner blocking contact. The burner
blocking contact only switches after expiry of the set delay time
when the minimum storage tank temperature [TS min] is
exceeded or if the set minimum momentary output for burner stop
[P min] is exceeded (example see fig. 6-9).
In the following example (fig. 6-9) we show a fictional sequence
of the storage tank temperature.
At time "t
1
" the minimum burner stop temperature, defined in the
operating parameter "TS min", is exceeded for the first time.
Since the storage tank temperature "T
S
" shortly afterwards falls
back below this value, this does not lead to activation of the
burner blocking contact.
Since the storage tank temperature "T
S
" is constantly exceeded
at time "t
2
", this leads to activation of the burner blocking contact,
with the delay "VBSK" at timet "t
3
". In a similar way, the burner
blocking contact is only deactivated at time "t
6
".
These settings are only accessible after entering the
expert password.
