Time program
Further information can be found in chapter
"Terminology" in the appendix.
Setting a time program
Factory setting: "Automatic"
During operation with standard room temperature,
DHW in the DHW cylinder is heated to the set DHW
temperature (see page 35).
The time phase for DHW heating automatically starts
half an hour earlier than the time phase for central
heating with standard room temperature. For example,
DHW heating will start 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.
You can change the time program individually in
accordance with your requirements.
Tap the following on-screen buttons:
1. "Menu"/" "
2. "DHW"
3. "Time program, DHW"
Note
Only if set to "Apartment building":
"Heating circuit 1 2 3" in the header to select the

5. OK/ to confirm
To see how to set a time program, see page 16.
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.
■
Any started water heating process continues until the
set DHW temperature is achieved, even if the stop
time has been reached.
