You can set up a time program for the following func-
tions:
■
Central heating/central cooling: see page 27.
■
Heating the heating water buffer cylinder: see
page 27.
■
DHW heating: see page 34.
■
DHW circulation pump: see page 35.
■
Electric booster heater: see page 37.
■
Quieter operation of air/water heat pumps: see
page 39.
■
Mechanical ventilation (in conjunction with a ventila-
tion unit): see page 42.
The time program allows you to divide the day into
sections. These are called time phases. It is for you to
decide what happens in these time phases, e.g.
whether your rooms should be heated to the standard
room temperature. For this, set an operating status
for each time phase.
■
You can set the time program individually, to be the
same, or different, for every day of the week.
■
You can select up to 8 time phases per day.
■
For each time phase you set the start and end
points.
The selected time phase is illustrated by a white bar
on the time chart. The length of the bar reflects the
length of time.
■
The individual operating status is indicated on the
time chart by bars of different heights.
Where several time phases overlap, the operating
status with the highest bar takes priority.
■
In the extended menu, you can call up the time pro-
grams under "Information": see page 51.
