Setting the time program for DHW heating

Factory setting (Vitotronic control unit):
"Automatic"
■ The time program for DHW heating is
made up of 1 to 4 time phases.
In the extended menu, you can scan
the current time program under "Infor-
mation" (see page 35).
■ "Automatic" can be selected for
DHW heating. This means that, in
standard heating mode (see page 13),
the DHW is reheated to the set tem-
perature. To ensure that hot water is
available at the start of standard heat-
ing mode, the time phase for DHW
heating automatically begins half an
hour earlier than the time phase for
standard heating mode.
DHW is heated in accordance with the
set DHW temperature and time pro-
gram.
ç
OK
■ If you don't want automatic mode, you
can select "Individual" and set up to
4 time phases per day for DHW heat-
ing. Set the "Start" and "End" points
for each time phase.
■ When adjusting the setting, bear in
mind that your heating system
requires some time to heat the DHW
to the required temperature.
