4.7.1 Entering time programmes (example for
heating)
Using the time programmes you can allocate up to three
time windows per weekday, or block of days (e.g.
Mo - Fr). In these time windows, the heating system
maintains the room temperature that you have selected,
the so-called comfort temperature.
Outside the time windows, the room temperature is
set back. The set-back temperature can also be changed.

Note!
If you programme the control to match your
lifestyle in the most optimum manner then you
will save energy whilst maintaining heating
comfort.
The way in which the time window is programmed is
described in the following example for heating circuit 1.
You can define time windows in a similar way for hot
water and for a circulation pump .
