Setting The Time Program For Dhw Heating - Viessmann VITOCAL 300-G Operating Instructions Manual

Setting the time program for DHW heating

■ The time program for DHW heating is
made up of time phases. Set an oper-
ating status for each time phase
("Top", "Normal", "Temp. 2", see
page 32).
At the factory, DHW heating is set to
operate 24/7 (one time phase from
0:00 to 24:00 h for every day of the
week with the operating status "Top").
■ You can select up to 8 time phases.
Set the start and end points for each
time phase. Between these time pha-
ses, no DHW is heated; only the frost
protection for the DHW 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 DHW cylinder to the required
temperature. Accordingly, set the start
and end times correspondingly earlier
or use the functions "Start optimisa-
tion" (see page 33) and "Stop opti-
misation" (see page 33).
■ In the "Advanced menu", you can scan
the current time program under "Infor-
mation" (see page 42).
Settings in the extended menu:
1.
2. "DHW"
3. "DHW 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 (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.
Example:
■ Time program for Monday ("Mo")
■ Time phase !:
5:30 to 8:00 h: "Normal"
■ Time phase ?:
8:00 to 14:00 h: "Top"
■ Time phase §:
16:30 to 17:30 h: "Temp. 2."
■ Time phase $:
17:30 to 22:00 h: "Normal"
