A Operating instructions – 5 Programming heating periods
5.3 Basic programme
If the change-over times are not altered, the room
thermostat operates according to the factory-set basic
programme:
Heating period with daytime temperature:
6.00 a.m....10.00 p.m.
Drop period with night-time temperature:
10.00 p.m....6.00 a.m.
Night-time temperature: 15°C.
On each of the seven days of the week between
6.00 a.m. tp 10.00 p.m. the factory-set room
thermostat VRT-P2D controls the room temperature to
the value set at the temperature selector (see chapter
4.1). In the meantime, from 10.00 p.m. to 6.00 a.m.,
the thermostat sets the room temperature to the night-
time temperature of 15°C (chapter 4.2).
Thus, it is already possible sensibly to control the
temperature after setting the time.

With the setting key – (11), the time is set back in
