Setting the time program for DHW circulation...
At the factory, no time phases for the
DHW circulation pump are set, i.e. the
DHW circulation pump is switched off.
■ You can select up to 8 time phases.
Set the start and end points for each
time phase. The DHW circulation
pump remains off in between time pha-
ses.
■ In the "Extended menu", you can scan
the current time program under
"Note" (see page 40).
Note
Also, enabling the DHW circulation
pump is only advisable for those times
when DHW is actually drawn.
Settings in the extended menu:
1.
2. "DHW"
3. "DHW circ time prog"
4. Select the part of the week or day.
5. Select a time phase ! to (. The
selected time phase is illustrated by a
white bar inside the time diagram.
6. Set the start and end points for the
relevant time phase. The length of the
white bar inside the time diagram is
matched accordingly.
7. Select the required operating status.
The individual operating status is dis-
played by bars of different heights
inside the time diagram (see the fol-
lowing example).
Note
Where several time phases overlap,
the operating status with the highest
bar takes priority.
