Objects A,B,C - presence/absence
The channels in which the behavior of the device is
linked to the presence always have 3
communication objects associated with it.
The configurations of these objects are present in a
dedicated page <Channel x> Outputs
Objects A and B are 1-bit objects; for each of them
it can be defined which telegram is linked to
presence ("1" or "0") and whether the presence,
absence or both telegram must be sent.
Output A (same parameters for Output B)
Activates the stand-by function whose parameters are
configurable in a dedicated page for each channel.
Object C can be configured with different data
points: 1 byte (signed or insigned), 2 bytes (signed or
unsigned), 2 floating bytes; in this way it is possible
to use each channel to send scenario, percentage,
hvac, temperature, brightness, etc setpoint values
on the presence, absence or both events.

Delay for sending object C respect to objects A and B.
Stand-by function (corridor function)
The stand-by function is connected to presence
detection; by activating this function the device, at
the end of the follow-up time, does not turn off the
lights but still keeps them on, typically at a lower
brightness level to save energy but avoiding that the
area remains completely in the dark.
A typical application concerns the lighting of
corridors. If there are offices with an adjacent
corridor it is possible to manage the corridor
lighting without installing a dedicated sensor. A
channel of one of the sensors located in the offices
will control the corridor lights and use the sensors
located in the other offices as remote sensors. When
at least one of the offices is occupied the light in the
corridor remains on, when instead all the offices
remain empty the corridor can go into stand-by
remaining with the light on at a reduced brightness
level to facilitate the passage of people who have to
walk through it . If the light is controlled in on / off
mode with a one-bit object, it is possible to keep
the light on during standby time and activate
(optionally) a warning of entry into standby time
with a short (1 sec. ) switching off and on of the
light.
Activates the stand-by function whose parameters are
configurable in a dedicated page for each channel.
Output A (same parameters for Output B)
Activates the warning function for channels with 1-bit
output, i.e. those channels the constant lighting function
is not configured depending on presence.
