Heartbeat (Periodic Alive Notification) [enabled/disabled]: incorporates a
one-bit object to the project ("[Heartbeat] Object to Send '1'") that will be
sent periodically with a value of "1" to notify that the device is still working (still
alive).
Note: the first sending after download or bus failure takes place with a delay
of up to 255 seconds, to prevent bus overload. The following sendings
match the period set.
Device Recovery Objects (Send 0 and 1) [disabled/enabled]: this
parameter lets the integrator activate two new communication objects
("[Heartbeat] Device Recovery"), which will be sent to the KNX bus with
values "0" and "1" respectively whenever the device begins operation (for
example, after a bus power failure). It is possible to parameterise a certain
delay [0...255] to this sending.
Ambient Luminosity Sensor [enabled/disabled]: enables or disables the
ambient luminosity sensor. When enabled, a new tab is added in the tree on
the left. For more information, see section 2.1.1.1.
