4.15.2 Setting/downloading parameter 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 operation via Popcard (most parameters)
Most parameters can be changed during operations using the OZW772 web server.
ETS is an engineering tool used to fully commission RDG2..KN KNX room
thermostats. Device address, application, and control parameters can be defined
and downloaded via ETS.
Note: If users abort operation during commissioning, full commissioning cannot be
restarted until the device reboots. Before rebooting, only the application can be
downloaded.
Connecting a KNX commissioning/operating tool to the RDG2..KN is described in
Commissioning.
4.15.3 Commissioning parameter via Smartphone app PCT
Go
The Siemens smartphone application Product Commissioning Tool (PCT Go) is a
commissioning tool to:
● Read and write thermostat parameters
● Set the application (e.g. 2-pipe)
● Change settings (e.g. setpoints)
● Set KNX addressing (device address)
Quickly setting the devices is useful, if e.g.:
● System and system commissioning tools are not available.
● Function and wiring test need to be carried out.
● The thermostats are used standalone.
When set locally with the PCT Go app, the device can be reset using the system
tools and reconfigured as needed.
PCT Go is available for phones (version 8 or higher) compatible with NFC. It can
be downloaded from Google Play store.
PCT Go uses NFC (Near Field Communication) while the device is either powered,
or unpowered, even from the individual package.
To read or write settings, the smartphone must have NFC embedded and activated,
and the phone must be held close to the NFC antenna (in the thermostat) at a
distance up to ± 2 cm.
