Setting The Time Program For The Dhw Circulation Pump - Viessmann VITODENS Operating Instructions Manual

DHW heating
Time program
This means that during operation with
standard room temperature (see
page 25), the DHW in the DHW cylinder
will be heated to the set DHW tempera-
ture. 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 operation with
standard room temperature.
