(here: Target room temperature)
Fig. 4.4 shows a programmed time window with
corresponding target room temperature (21 °C).
In the lower diagram, the value of the target room
temperature at (

uses this target room temperature until the start of the
time window.
From this point (
2 ) the control system uses the target
room temperature of the time window (21 °C).
At (
3 ) the target 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).
(You can find more information on time windows in the
operating manual of the VRC 430 controller.)
