Art. No. SC 1000 KNX
Additional information on the Presence function / Comfort extension
With presence detection, the room temperature controller can quickly change over to a comfort
extension upon push button actuation or go into the Comfort mode when movement by a person
in the room is detected. In this connection, the "Presence detection" parameter in the "Room
temperature control -> Controller functionality" parameter node sets whether presence detection
should be movement-controlled by a motion detector or manual through presence button
actuation...
- Presence detection by the presence button
If you configure the presence button for the presence detection, you can select the
"presence button" setting from the KNX channel functions or from the push button functions
of the extension module (function selection "operating mode switchover, internal"). In
addition, the "Presence object" is enabled. In this way, you can actuate the presence
button or use a presence object value = "1" to change over to comfort extension when the
Night or the Frost/heat protection mode is active (not activated by the "window status"
object). The extension will be automatically deactivated as soon as the configured "Length
of comfort extension" time has elapsed. If you press the presence button once more, or if
the presence object receives a value ="0", you can deactivate the comfort extension earlier.
You cannot re-trigger such extension 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 you can operate the presence button or use a presence
object value = "1" to change over to the comfort mode. This will also be the case if you
have configured the length of comfort prolongation to "0". The comfort mode will remain
active as long as the presence function remains active, or until another operating mode
comes into effect.
The presence object or the presence function, respectively, will always be deleted
whenever a change-over to a different operating mode takes place, or after a forced
operating mode has been deactivated (associated with KNX forced change-over). A
presence function activated before a device reset (programming operation, bus voltage
failure) is always deleted, along with the object value, after the reset.
- Presence detection by the motion detector
If a motion detector is configured for motion detection, then the controller only evaluates
the "Presence object". With this object, it is possible to integrate motion detectors into room
temperature control. If a movement is detected ("1" telegram) the controller will change
over into the Comfort mode. In this connection, it is irrelevant what has been set by the
change-over objects or by local control directly on the device. Only a window contact or the
KNX forced object are of higher priority.
After the movement delay time has elapsed in the motion detector ("0" telegram), the
controller will return to the operating mode which was active before presence detection, or
it will compensate the telegrams of the operating mode objects received during presence
detection, respectively. During active presence detection, you cannot change-over the
operating mode on the room temperature controller.
A presence function activated before a device reset (programming operation, bus voltage
failure) is always deleted, along with the object value, after the reset. In this case, the
motion detector must transmit a new "1" telegram to the controller to activate the presence
function.
i If the motion detector is configured for presence detection, it is always possible to configure
the presence button in the KNX channel functions or push button functions of the extension
module. However, this parameterisation then has no effect.
