Control functions
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:

tion has been terminated or if code
