Screed drying
When enabling screed drying, observe the information
provided by the screed manufacturer.
When the screed drying function is activated, the heat-
ing circuit pumps of
all
heating circuits are switched on
and the flow temperature is maintained in accordance
with the selected profile. After completion (30 days),
the heating circuits with mixer are automatically con-
trolled with the set parameters.
Screed drying is adjusted in the system configuration:
■
0 = OFF
■
2 = Temperature profile A
■
3 = Temperature profile B
■
...
■
7 = Temperature profile F
Note
During screed drying, DHW heating is not available.
Observe EN 1264. The report to be provided by the
heating contractor must contain the following details
regarding heat-up:
■
Heat-up data with the relevant set flow temperatures
■
Max. flow temperature achieved.
■
Operating state and outside temperature at handover
Note
Temperature profile 6 ends after 21 days.
The function continues after a power failure or after the
control unit has been switched off. When screed drying
has completed or been manually switched off, the sys-
tem is controlled in accordance with the selected
parameters.
