4.5.1
Channel selection via NFC
The radio channel used by PTM 535BZ can be selected via the NFC interface. To do so, the
user first needs to determine the radio channel used by the ZGP network that shall receive
the radio telegrams of PTM 535BZ. This is typically done by means of a commissioning ap-
plication (such as an application on a smartphone) that can communicate with the devices
in the ZGP network (for instance via a gateway).
In this process, the user will first determine the radio channel used by the ZGP network via
the commissioning application and then configure PTM 535BZ via its NFC interface to use
this radio channel. Smartphones with NFC interface allow combining these two steps within
one application which enables quick and reliable configuration of PTM 535BZ.
4.5.2
Channel selection via LRN button
While channel selection via NFC is the preferred way of configuring PTM 535BZ, certain sce-
narios exist where this is not possible. For instance, a simple lighting control application
might consist only of ZGP switches and ZGP receivers without a gateway that would allow a
smartphone application to connect to the network.
For these cases, PTM 535BZ offers a manual mode of channel selection which is triggered
by pressing and holding the LRN button while actuating the connected ECO 200 harvester.
In manual channel selection mode, PTM 535BZ will announce its identity (Source Address,
Device ID, Application Information, Security Material) sequentially on different radio chan-
nels.
If a ZGP network operates on the currently used radio channel and is configured to accept
new devices (for instance by pressing a dedicated button on the receiver) then it can signal
to the installer (for instance by blinking the controlled light) that PTM 535BZ is now operat-
ing on the right radio channel, that its Commissioning Telegram has been received and that
PTM 535BZ is now part of the ZGP network.
At this point, the installer has to release the LRN button to complete the channel selection
sequence of PTM 535BZ and trigger a data telegram (by actuating the connected ECO 200
harvester after the LRN button has been released) to signal to the receiver that the config-
uration has been completed.
PTM 535BZ will continue to operate on the selected channel until the channel selection pro-
cess is started again (for instance because the product using PTM 535BZ has been moved
to a different room and should now be part of a different ZGP network).
Note that PTM 535BZ will change to a different channel if the LRN button is pressed
during at least three consecutive ECO 200 actions (e.g. press
–
release - press).
Therefore, it is strongly recommended to transmit a data telegram after completion
of the channel selection sequence to avoid unintentional channel reconfiguration when
the LRN button is pressed the next time.
Channel selection via the LRN button can be disabled via the NFC interface as de-
scribed in
Chapter 5.6.9
