(hier: Target room temperature

The top diagram in Fig. 4.11 shows a programmed time

window (see Section 4.7.1) and corresponding room tar-

get temperature (21 °C).

In the lower diagram, at (1) the value of the room tem-

perature is changed (20 °C). The control system uses

this value until the start of the time window.

From here (2) the control system uses the room tem-

perature of the time window (21 °C).

At (3) the value of the room temperature is changed

(17 °C).

The control system uses this value up to the end of the

time window (4).

After the time window, the control system uses the

night set back temp (15 °C).

Note!

This also applies to the hot water target value.
