3.9 PRESENCE DETECTOR
Presence detectors (like Zennio’s
ZN1IO-DETEC sensor), installed inside a room,
permit multiple applications, such as switching lights on and off, detecting intruders,
dimming lights, etc. Besides, if combined with the IRSC controller, presence detectors
contribute to energy saving by switching the A/C system off when the room is empty.
Figure 12. Presence Detector
Activating this feature brings the 1-bit "Presence detection" object, which should be
linked to the presence detection object, so that it is aware of presence/no presence
changes.
Also the "Waiting Period" parameter becomes visible, and defines the time period (in
minutes) that IRSC Plus should wait after receiving the value "0" (empty room) through
the detection object before switching the A/C unit off.
As soon as the "Presence detection" object receives the value "1", IRSC Plus
considers the room is again occupied, so if the value "0" arrives again, the time count
will start again.
Note:
during the “no detection” state, the device will still accept requests from the bus
and update its objects according to them. Although the machine is off, as soon as it is
switched on again, IRSC will send the proper commands to update its state as
corresponding. Because of this, in the particular case of receiving a switch-off order
under “no detection” (therefore, being the machine already off), a later presence
detection will not make the A/C unit turn on again as IRSC will then send an order to
switch it off. In such case, an explicit ON order will be required.
