DHW heating
Setting the time program for DHW heating
■ "Automatic" is set for the DHW circu-
lation pump time program. In other
words, the DHW circulation pump
operates in parallel to the DHW heat-
ing time program (see page 29).
■ In the extended menu "Information",
you can scan the current time program
(see page 35).
■ If you don't want automatic mode, you
can select "Individual" and set up to
4 time phases per day for the DHW
circulation pump. Set the "Start" and
"End" points for each time phase.
Note
Activating the DHW circulation pump is
only advisable for those times when
DHW is actually drawn.
The time program for the DHW circula-
tion pump is set in the same way as the
time program for DHW heating is set
(see page 27).
