The control of the boiler depends upon the set room
temperature. The controller ensures that the target
room temperature is achieved quickly and is maintained
at this value.

temperature is highlighted. After a delay of 1 second,
you can change the target room temperature:

Fig. 4.10 Changing the room temperature in the basic display
The new room temperature is used instead of the
programmed temperature until the end of the current
time programme. This duration depends upon the
operating mode; see also Chapter 4.4.
4.4 Changing the target room temperature
If you change a target value - either the room
temperature or the hot water target value - in the basic
display or in the default display, the new value overrides
the programmed temperatures.
When in „Manual“ mode, the control uses the temporary
temperatures until either the operation mode or the
temperature is changed.
When in „automatic“ mode, the control uses the
temporary temperature until the next time window
starts (if you have changed the set target value outside
a time window) or until the end of the current time
window (if you have changed the set target value within
the time window); see Fig. 4.11.
