4.2.4.3.2 Operating functions

Operating mode switchover
Change-over of the controller operating mode can be effected in accordance with the standard
function block for room temperature controllers defined in the KNX handbook with two
1-byte communication objects. The operating mode can be switched over with the normal and
with the forced objects. The "B.Controller extension operating mode switchover" object offers a
selection between the following operating modes...
- Comfort mode
- Standby mode
- Night mode
- Frost / heat protection
The "B.Controller extension forced-object operating mode" communication object has a higher
priority. It permits forced switching between the following modes of operation...
- Auto (normal operating mode switchover)
- Comfort mode
- Standby mode
- Night mode
- Frost / heat protection
The operating mode transmitted to the bus on a button press of the controller extension is
defined by the parameter "Operating mode on pressing the button". Depending on the
configured functionality, it is possible that ...
- Either one of the above-mentioned modes is activated (single selection) on the press of the
button,
- Or the device is switched over between various modes (multiple selection) each time a button
is pressed.
i Notes on multiple selection:
In order to ensure that a switchover from one operating mode to another works properly
even from different locations, the operating mode objects of the controller and those of all
controller extension push button sensors must be interlinked and have their "Write" flag set.
In the objects concerned, this flag is set by default
By checking the linked operating mode switchover object, the controller extension knows
which of the possible operating modes is active. Based on this information, the device
changes over into the next operating mode in sequence when a button is pressed. In the
event that none of the possible operating modes is active, the next operating mode in the
sequence is set to '"Comfort" mode (in case of "Standby - >Night" to "Standby" mode). As
far as switching over between the forced operating modes and "Auto" is concerned, the
device switches into the "Auto" operating mode when none of the configured operating
modes is active.
i It is not possible to program a reaction on release of the button. A long button-press is
evaluated in the same way as short one and switches into the corresponding operating
mode insofar as this is acceptable for the controller.
i If a status LED is to indicate the current operating mode, the status LED function must be
programmed for "Operating mode indication" and its status object be linked with the
corresponding group address for operating mode switchover with normal or high priority.
