Setting the time program for DHW circulation pump

Further information about the DHW cir-
culation pump can be found under "Ter-
minology" on page 59.
■ The time program for the DHW circu-
lation pump is made up of time pha-
ses. Set an operating status for each
time phase ("5/25 cyc.", "5/10 cyc.",
"ON", see page 35).
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 "Advanced menu", you can scan
the current time program under "Infor-
mation" (see page 42).
Note
Also, enabling the DHW circulation
pump is only advisable for those times
when DHW is actually drawn.

relevant time phase. The length of the

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.
