4.7.1 Entering time programmes (example for
heating)
Using the time programmes you can set up to three time
windows per weekday or block of days (e.g. Mo - Fr). In
these time windows, the heating control system provides
the room temperature you have entered, the so-called
comfort temperature. Outside the time windows the
room temperature is set back. You can also set this set-
back temperature.

Note!
If you programme the control to match your
lifestyle in the most optimum manner then you

comfort.
The way to set the time windows is shown in the
following example for the heating circuit. Time windows
can be set in the same way for the hot water preparation
and for a circulation pump.
