Fill program
In the delivered condition, the diverter
valve is set to its central position, ena-
bling the system to be filled completely.
After switching ON the control unit, the
diverter valve no longer goes into its cen-
tral position.
Afterwards, the diverter valve can be
moved via code "2F:2" into the central
position. In this position, the control unit
can be switched OFF, and the system
can be filled completely.
Filling with the control unit switched
ON
If the system is to be filled with the control
unit switched ON, the diverter valve will
be moved to its central position via code
"2F:2" and the pump will be started.
The burner shuts down if this function is
enabled via coding address "2F". The
program is automatically disabled after
20 min, and coding address "2F" is set to
"0".
Screed drying function
The screed function enables screeds to
be dried. For this, always observe the
details specified by the screed manufac-
turer.
When the screed drying function is acti-
vated, the heating circuit pump of the
mixer circuit is switched ON and the flow
temperature will be held at the selected
profile. After completion (30 days), the
mixer circuit will again be regulated auto-
matically via the set parameters.
Observe EN 1264. The report to be pro-
vided by the heating contractor must
contain the following heat-up details:
■ Heat-up data with respective flow tem-
peratures
■ Max. flow temperature achieved
■ Operating condition and outside tem-
perature during handover
The various temperature profiles are
adjustable via coding address "F1".
The function continues after power fail-
ure or after the control unit has been
switched OFF. "Heating and DHW" will
be started after the screed drying func-
tion has been terminated or if code
"F1:0" is manually adjusted.
