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.
