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: "Selection 2/2" -> "System" ->
"Modulation" navigate to the "Stage" (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 "Output".
Ɣ Noise-intensive stages should be set to "No" in the parameter
"Active".
Î The stage is skipped when the solar operating pump P
S
is
activated. The block remains, even after "Switching
OFF/ON the controller. It can be cancelled again by set-
ting 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: "Selection 2/2" -> "System" ->
"Correction values" select the correction parameter
(see fig. 6-7) and change in accordance with tab. 6-4.

6.3.10 Burner inhibit contact
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. This requires the connection
cable BSKK ( 16 41 10) offered as an accessory. If the solar
system reaches a momentary output, adjustable by the heating
expert (menu path: "Selection 1/2" -> "Parameter selection" ->
"Operating parameter "P min") or if the storage tank heated up to
the minimum storage tank temperature adjustable by the heating
expert (Operating parameter "T
S
min" see tab. 6-5) the burner is
deenergised, for example, via a contact. The parameter setting
for the burner blocking contact is described in fig. 6-7.
Using the parameter "Time VBSK", it is possible to set a delay in
the switching time for the burner blocking contact. The burner
blocking contact only switches after expiry of the set delay time
when the minimum storage tank temperature "T
S
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 "T
S
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.
