Fig. 3.2 Automatic heating operation: Example of setting the
target room temperatures for different times of day
In Fig. 3.2 you can see a section from a timer pro-
gramme. The time of day is given on the horizontal axis
and the target room temperature is on the vertical axis.
The diagram describes the following programme pro-
gression:
1 Until 06.00 hrs. a room temperature of 15 °C
(night set back temperature) is in effect.
2 The first time window starts at 06.00 hrs.:
From this point onwards a target room tempera-
ture of 21 °C is effective.
3 The first time window ends at 09.00 hrs.:
From this point onwards a target room tempera-
ture of 15 °C is effective.
4 A further two time windows of 21 °C follow.
The way in which the time windows influence the
heating control can be simply explained as follows:
When you operate your heating installation in the Auto
mode, the controller activates the preset time windows
in which your installation heats the connected rooms to
a defined temperature (
¬ Target room temperature ).
Outside these time windows, the heating installation is
controlled so that the connected rooms cool down to a
defined temperature (
¬ Night set back temp ). When
the night set back temperature is reached, the control-
ler ensures that the heating installation maintains this
temperature until the start of the next time window.
Thus any further cooling of the apartment is prevented.
i
Get your expert technician to advise you
about the optimum setting of the heating
curve, as the measured outside temperature
and the preset heating curve will also affect
the control of the heating.
