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 29).
The time phase for DHW heating automatically 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.
You can change this time program individually in
accordance with your requirements.
