Priority assignment PA
Priorities can be set for program diagrams with multiple consumers on one heat generator.
This menu item is only displayed for program diagrams with priority. The priority assignment
(output assignment) is adapted to the specific program diagram. The priority assignment
always refers to the pumps.
For pump/valve systems, the priority is always set
according to the basic diagram
. (ex works = OFF)
Settings: OFF, 123 to 321, or only 2 outputs (such as 12, 21,...)
Priority OFF Priority
A1 before A2
Priority
A2 before A1
Set values (max, min, diff)
The number of maximum thresholds, minimum thresholds, and differences is displayed
according to the set program number. The differentiation between similar thresholds (e.g.
max1, max2, max3) is displayed on the side by the index
1
,
2
or
3
). Each threshold
comprises two values. I.e. all switching thresholds are divided into on and off thresholds!
CAUTION:
When setting the parameter, the computer always limits the threshold value (such
as
max on
 ) when it approaches a certain temperature of the second threshold (such as
max off
 ) to prevent negative hysteresis. If a threshold cannot be changed any longer, the
second threshold has to be changed first.
All thresholds (
min
,
diff
,
max
) can be disabled individually. The respective threshold is
shut-down when the highest possible setting value is exceeded. For
min
and
max
, that is
149°C and for
diff
98K. In this case, the display just has a line ( - ) where the number would
be, and the partial function is considered not available.
The factory setting for the adjustment values (max, min, diff) is appropriately matched to the
diagrams, but must however be checked prior to commissioning and matched to the
individual requirements. The specific adjustment values are only loaded, if after setting the
program number, the factory setting is reloaded (press the bottom key (entry) while plugging
in). Only then should the controller be parameterised.
