Setting the time program for DHW heating
Factory setting: "Automatic"
This means that during operation with standard room
temperature (see page 18), the DHW in the DHW cyl-
inder 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 you will
have hot water available right at the beginning of oper-
ation with standard room temperature.
