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 in accordance
with the selected profile. After comple-

be regulated automatically 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 conditions 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.
