4.15.3 Commissioning parameter via Smartphone app PCT Go
The Siemens smartphone application Product Commissioning Tool (PCT Go) for
Android 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 Android 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.

DIP switche settings take priority:
●
If all DIP switches are set to Off (default), PCT Go can be used to change the
application (e.g. 2-pipe)
●
If an application is set via DIP switches, PCT Go cannot change it.
Change settings while the device is powered and running:
●
Application settings require a device reboot.
●
Settings such as setpoint and HMI tuning take effect a few seconds later.
Change settings while the device is unpowered:
●
Current thermostat settings can be read and written any time while unpowered
●
The thermostat needs to be powered to store the new settings and ensure they
are correct.
●
Each time the application is changed, the thermostat reloads the factory setting
for all control parameters, except KNX device and zone addresses.
●
The thermostat setting access can be password protected (P502). PCT Go
requires that the password be read and write-protected.
If the password is mistyped 5 times, the thermostat is locked, and the password
cannot be entered for 5 minutes.
●
Commissioning using PCT Go for Android can be disabled via parameters to
avoid unexpected changes of the thermostat (P500).
