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 presence detector or manual through presence button
actuation.
- Presence detection by the presence button
Presence detection by the presence button is configured under "Controller functionality".
Then the "presence object" is enabled, too. 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 extension 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 presence 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 presence 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 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 presence 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
presence detector must transmit a new "1" telegram to the controller to activate the
presence function.
Additional information on the window status and the automatic frost protection
The room temperature controller offers various options to change over into the Frost/heat
protection mode. In addition to switching-over by means of the corresponding operating mode
switch-over object, the frost/heat protection can be activated by a window contact, or
alternatively, the frost protection can be activated by an automatic temperature function. With
these options, the window contact or the automatic function has higher priority. You can use the
"frost/heat protection" parameter in the "room temperature control -> controller general"
parameter branch to set the way how such higher-priority switch-over will take place...
