i When changing over the operating mode, the objects "Comfort mode", "Standby mode",
"Night mode" and "Frost/heat protection" are updated by the controller and can be read out
when the appropriate Read flags are set. If the "Transmit" flag has been set for these
objects the current values will, in addition, be automatically transmitted to the bus when
they are changed. After bus voltage recovery or after initialisation of the controller, the
object which corresponds to the selected operating mode will be updated and its value
actively transmitted to the bus if the "Transmit" flag has been set.
i A change-over through the objects has the same importance as a local change-over on the
device. An operating mode set by an object can therefore be shifted by an operating mode
change-over on the device, if no higher-priority mode (e.g. window contact / motion
detector) is activated.
i In parameterisation of a presence button: the presence object will be active ("1") for the
period of an comfort extension. The presence object will be automatically deleted ("0") if
the comfort extension is stopped after the extension time has elapsed, or if the operating
mode has been changed by a higher-priority operation through the change-over objects or
by local control. The controller therefore automatically resets the status of the presence
button when an object is received via the operating mode objects.
