process exceeds the threshold set on par. 268 or until the time in minutes set on par. 269
("Softstart Time" word 2084).
If the Sof-Start function is active the automatic/manual Tuning function cannot be activated.
8 Reading and confi guration through NFC
The controller ATR224 and DRR224 is supported by the App MyPixsys: using an ANDROID smartphone
with NFC connection it is possible to program the device without using a dedicated equipment. The
App allows to read, set and backup all parameters which are stored into the internal memory of Pixsys
devices.
Procedure:
• Identify the position of the NFC antenna on the smartphone (usually central, behind the back cover)
or to one of the sides in case of metal chassis. The antenna is placed on the frontal panel: between

and FNC keys for the ATR224 and between
• Make sure that the NFC sensor of the phone is enabled or that there are no metal materials between
the phone and the device (ex. aluminium cover or with magnetic stand)
• It is useful to enable the system sounds on the smartphone, as the notification sound confirms that
the device has correctly been detected.
The App interface is provided with four tabs: SCAN, DATA, WRITE, EXTRA.
Select the first tab "SCAN" to read data stored into the internal memory of the device; place the
smartphone in contact with the controller frontal panel, making sure that the phone's antenna
matched with that of the controller.
Once detected the device, the App emits a notification sounds and proceeds with the model identifi-
cation and the reading of the parameters.
The graphic interface shows the advancement and switches to the second tab "DATA". It is now possible
to move the smartphone away from the controller to make the required modifications more easily.
The device parameters are divided into collapsible groups and are displayed with name, current value
and reference index to the manual. Click on a row to open the setting screen of the related parameter
with the detailed view of available options (in case of multiple choice parameters) or of the minimum/
maximum/decimals limits (for numeric parameters), included the text description (as per section n. 11
of the user manual). Once selected the chosen value, the related row will be updated and underlined
into the tab "DATA" (hold down the line to cancel modifications).
