Room temperature controller | Operating mode and setpoints
In this regard, the parameter "Presence detection" determines whether presence de-
tection is movement-controlled by a presence detector or done manually using a
presence button:

Presence detection by the presence button
The 1-bit communication object "Presence detection - Presence button" is en-
abled. An "ON" telegram to this object makes it possible to switch to the com-
fort extension if Night or Frost/heat protection mode (not activated by the "Win-
dow status" object!) is active. The extension will be automatically deactivated
as soon as the configured "Length of comfort extension" time has elapsed. A
comfort extension can be deactivated in advance if an "OFF" telegram is re-
ceived via the object of the presence button. You cannot re-trigger such exten-
sion time.
If you have set the length of comfort extension to "0" in the ETS, you cannot
activate a comfort extension from the Night or Frost/heat protection mode. In
this case, the operating mode will not be changed, although the presence
function has been activated.
If the standby mode is active, actuation on a presence object value = "ON" al-
lows a switchover to the Comfort mode. This will also be the case if you have
configured the length of comfort extension to "0". Comfort mode will remain
active as long as the presence function remains active, or until another operat-
ing mode is specified.
The presence function will always be deleted whenever a switchover to a dif-
ferent operating mode takes place, or after a forced operating mode has been
deactivated (associated with KNX forced switchover). In the event of a device
reset (voltage failure, ETS programming operation), an active presence func-
tion is always deleted.
If, during an active comfort extension and with a frost/heat protection
switchover being configured "via window status", a window is opened, then the
controller will activate frost/heat protection immediately. The comfort extension
remains active in the background and the configured time continues to elapse.
If the time elapses and the window remains open, the presence is reset and
an appropriate telegram is sent to the bus. However, if the window is closed
again before the time has elapsed, then the comfort extension is executed
again with the remaining run time.

Presence detection by the presence detector
Two 1-bit communication objects "Presence detection - Presence object" are
enabled. With this objects it is possible to integrate presence detectors into
room temperature control. If a movement is detected ("ON" telegram), the con-
troller will switch to Comfort mode. In this connection, it is irrelevant what has
been set by the switchover objects. Only a window contact or the KNX forced
object are of higher priority.
Both objects form an "Or" link of two presence detectors. In larger rooms, the
use of two presence detectors can be useful. As long as one of the two detect-
ors detects a presence, the controller remains in Comfort mode.
