7.11 Floor drying
Caution.
Risk of damage to the product caused by
impermissible purging
Without purging the heating circuit, the sys-
tem may become damaged.
▶ If the screed drying is activated without a
system control, purge the system manu-
ally. No automatic purging takes place.
– You can use this function to "dry heat" freshly laid screed
in accordance with the construction regulations, accord-
ing to a defined time and temperature schedule, without
the need for a system control to be connected.
If there is no electric back-up heater, screed drying is
only possible with this product if the return temperature is
above 10 °C. This corresponds approximately to an outdoor
temperature of +5 °C. At outdoor temperatures below
+5 °C, there is a risk of increased icing of the fin-type heat
exchanger in the outdoor unit.
When screed drying is activated, all the selected operating
modes are interrupted. The function controls the flow tem-
perature of the controlled heating circuit according to a pre-
set programme, regardless of the outdoor temperature.
The display shows the target flow temperature. You can
manually set the current day.
