Setting A Time Program For The Heating Water Buffer Cylinder - Viessmann VITOCAL 300-G Operating Instructions Manual

Setting a time program for the heating water buffer cylinder

■ The time program for the heating water
buffer cylinder is made up of time pha-
ses. Set an operating status for each
time phase ("Top", "Normal", "Fixed
val.", see page 38).
At the factory, heating water buffer cyl-
inder is set to the operating status
"Normal" 24/7 (one time phase from
0:00 to 24:00 h for every day of the
week).
■ You can select up to 8 time phases.
Set the start and end points for each
time phase. Between these time pha-
ses, the heating water buffer cylinder
is not heated; only the frost protection
for the heating water buffer cylinder is
active.
■ You can set the time program individ-
ually.
When setting time programs, note that
your heat pump requires some time to
heat the heating water buffer cylinder
to the required temperature.
■ In the "Advanced menu", you can scan
the current time program under "Infor-
mation" (see page 42).
Settings in the extended menu:
1.
2. "System"
3. "Buffer cyl time program"

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 (see the follow-
ing example).
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.
