Table 10: Communication objects – Display behavior
After each restart, the
Day/Night object
is set to day; even if the communication object is not linked
at all.
The
presence object
is used to deactivate the display when no one is in the room. It can, for example,
be controlled via a presence detector.
If the presence object is set to the value 0, the display turns off and is only switched on again when
the object is set to 1 or a key is pressed. If a key is pressed with the value 0 (= no presence), the
display remains switched on until the display switches to standby mode. If Standby is deactivated,
the display remains active for 120 seconds.
After each restart, the presence object is set to the value 1 (= presence); even if the object is not
linked.
The presence object switches back and forth between the states "display is switched on" or "display
is switched on and exits standby" and "display off" depending on the parameterisation.
