Heating water buffer cylinder
Setting a time program
■ The time program for the heating
water buffer cylinder is made up of
time phases. Set an operating status
for each time phase ("Top", "Stand-
ard", "Fixed value", see page 43).
Factory setting:
One time phase from 0:00 to 24:00 h
for every day of the week with operat-
ing status "Standard".
■ 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 extended menu, you can scan
the current time program under "Infor-
mation" (see page 47).

(see page 43). The individual oper-
ating status is displayed by bars of dif-
ferent heights on the time chart (see
the following example).
Note
Where several time phases overlap,
the operating status with the highest
bar takes priority.
