4.7.1 Entering timer programmes
(example for heating circuit)
Using the time programmes you can allocate up to three
time windows per day, 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.
h
Note!
If you set the timer windows carefully to suit
your lifestyle, you will save energy without los-
ing any heating comfort.
The next section describes how to set the timer win-
dows using heating circuit 1 as an example. You can de-
fine time windows in a similar way for hot water and for
a circulation pump .
Turn the left-hand dial until screen 2 (HC1 time
