27:15
Cyclical heating time 15 min.
If the DHW cylinder with priority
has been heated up, the DHW cyl-
inder without priority is heated for a
maximum duration equal to the set
cyclical heating time.
27:5
to
27:60
Cyclical heating time is adjustable
from 5 to 60 min.
28:3
Cyclical pause time 3 min.
After the set cyclical heating time
for the DHW cylinder without priori-
ty has expired, the rise in collector
temperature is captured during the
cyclical pause time.
28:1
to
28:60
Cyclical pause time adjustable from
1 to 60 min.

A2:0
Without cylinder priority for heating
circuit pump
A2:1
Cylinder priority applies only to mix-
ers. The mixer is closed during cylin-
der heating. The heating circuit
pump is running.
A2:3
to
A2:15
Modulating priority for mixers. The
heating circuit receives a reduced
amount of heat.
A3:2
Outside temperature below 1 °C:
Heating circuit pump "ON"
Outside temperature above 3 °C:
Heating circuit pump "OFF"
A3:-9
to
A3:15
Heating circuit pump "ON/OFF" (see
the following table)
!
Please note
With settings below 1 °C there is a risk that pipes outside the thermal envelope of the building could freeze
up.
Standby mode in particular must be taken into consideration, e.g. during holidays.
