4.15.2 Parameters setting/download via tool
The control parameters can be adjusted via bus either by parameter download
during commissioning or during normal operation with a tool like ACS.
With the ACS tool, the parameters can be changed…
● during commissioning via parameter download (all parameters)
● during operations via Popcard (most of the parameters)
Most parameters can be changed during operations using the OZW772 web
server.
ETS is an engineering tool and can be used for the full commissioning of the
RDG2..KN KNX room thermostats. Device address, application, and control
parameters can be defined and downloaded via ETS.
Note: If user aborts the operation during full commissioning, the operation of full
commissioning cannot be done again until device reboot. Before rebooting, only
application can be downloaded.
Connecting a KNX commissioning/operating tool to the RDG2..KN is described in
Commissioning.
4.15.3 Parameters commissioning via Smartphone APP PCT Go
The Siemens smartphone application Product Commissioning Tool (PCT Go) for
Android is a commissioning tool that allows user to:
● Read and write parameters of the thermostats
● Set the application (e.g. 2-pipe)
● Change settings (e.g. setpoints)
● Set the KNX addressing (device address)
It can be useful to quickly set the devices if for example:
● The system and system commissioning tools are not available.
● Function and wiring test need to be carried.
● The thermostats are used as standalone.
Once locally set with the PCT Go app, the device can be reset by the system tools
and reconfigured if needed.
The APP PCT Go is available for Android phone (version 8 or higher) compatible
with NFC. It can be download on Google Play store.
PCT Go APP works via NFC (Near Field Communication) and can be used while
the device is either powered, or unpowered, even from the individual package.
In order to read or write settings, the smartphone shall have NFC function
embedded and activated, and user needs to put the phone closing to the NFC
antenna (build in the thermostat) at a distance up to ± 2 cm.
