4.7.1 Entering time programmes (example for

heating circuit)

The timer programmes can be used to specify up to

three time periods for each day or each block of days

(e.g. Mo - Fr). During these time periods the heating

control system maintains the set room temperature, the

so-called comfort temperature. The temperature is set

back outside these time periods.

Note!

If you carefully adjust the time window accord-

ing to your lifestyle, you will save energy with-

out losing your heating comfort.

The procedure for setting the time windows is described

below heating circuit 1 as an example Time windows can

be set in the same way for the hot water preparation

and for a circulation pump.
