NOTE
If the error message “Power screed heating” appears (= er-
ror number 730), this is only an indication that the screed
heating program could not process a ow temperature
level in the specied time interval. The screed heating pro-
gram continues to run nevertheless. The error message
can only be acknowledged if the screed heating program
has nished or has been manually switched o
As long as the screed heating program is running, the corre-
sponding program symbol will appear in the navigation screen:
Manually terminating screed heating program
Starting screed heating program
NOTE
While the screed heating program is running, -10°C is dis-
played as the outdoor temperature. It is not possible to
heat water.
NOTE
In the screed heating program, all connected heat generators
are released if necessary. However, the following applies:
A heating system is designed for heating in general and
not for heating screed. It may therefore be necessary for
the screed heating phase to integrate additional heat gen-
erators in the system.

Answer the conrmation prompt.
NOTE
If you respond to the conrmation prompt with , the
screen will change back to the menu “Screed heating”.
After starting the screed heating program, the programmed ow
temperature levels are automatically executed in succession.
The time interval set for a ow temperature level is not necessar-
ily the actual time which is necessary to reach the next ow tem-
perature level. Depending on the heating system and power of
the heat pump, it may take varying lengths of time until the next
ow temperature level is reached.
If a ow temperature level is not reached on account of too low a
heating power, a corresponding error message will appear in the
screen. The error message informs you about the ow tempera-
ture level which has not been reached. However, the screed heat-
ing program continues running and attempts to reach the next
ow temperature levels.
NOTE
After expiry of a ow temperature level, the relevant time
interval is set to “0h”. This ensures that the screed heating
program continues after a potential power failure at the
start of each ow level at which it was interrupted.
