DHW heating

Setting the time program for DHW heating

■ The time program for DHW heating is
made up of time phases. One time
phase from 5:30 to 22:00 h for every
day of the week is set at the factory.
■ Automatic mode is set at the factory
for DHW heating. This means that, in
standard heating mode, the DHW is
reheated to the set temperature. To
ensure that hot water is available at
the start of standard heating mode, the
time phase for DHW heating begins
automatically half an hour earlier than
the time phase for standard heating
mode.

■ If you don't want the automatic mode,
you can select up to 4 individual time
phases per day for DHW heating,
which can be the same for every day
of the week or different. Set the start
and end points for each time phase.
■ When setting, bear in mind that your
heating system requires some time to
heat the DHW to the required temper-
ature.
■ In the "Extended menu", you can scan
the current time program under "Infor-
mation" (see chapter "Scanning infor-
mation", "DHW" group).
