Setting the time program for DHW heating
Factory setting: "Automatic"
During operation with standard room temperature (see
page 19), the DHW in the DHW cylinder will be heated
to the set DHW temperature. The time phase for DHW
heating automatically starts half an hour earlier than
the time phase for central heating with standard room
temperature. This means hot water is already available
when your system starts operating at standard room
temperature.

Note
■ The DHW is not heated between the time phases.

■ When adjusting the setting, bear in mind that your
heating system requires some time to heat the DHW
cylinder to the required temperature.
