"Terminology" in the Appendix.
Setting the time program for DHW heating
Factory setting:
"Automatic"
During operation with standard room temperature,
DHW in the DHW cylinder is heated to the set DHW
temperature. The time phase for DHW heating auto-
matically starts half an hour earlier than the time phase
for central heating with standard room temperature.
DHW heating will start, for example, at 05:30 h if the
start time for central heating is 06:00 h. This means
hot water is already available when your system starts
operating at standard room temperature.
Note
In delivered condition, central heating is set at 00:00 to
24:00 h. This means that hot water will also be availa-
ble to you round the clock.
You can change this time program
individually
in
accordance with your requirements.

Note
■
The DHW is not heated between the time phases.
Frost protection for the DHW cylinder is active.
■
When setting time programs, bear in mind that your
heating system requires some time to heat the DHW
cylinder to the required temperature.
■
Even if the start-up time is past, DHW heating that
has already started will be completed first.
Increased DHW hygiene
This function can be used to heat the water in the
DHW cylinder to a higher set DHW temperature.
Your heating contractor can enable this function by
specifying a second set DHW temperature.
