● Disconnect thermostat from power supply before removing from the
mounting plate.
● If a KNX bus power supply is connected to the line with communicating
thermostats and Synco controller, the internal KNX power supply of the Synco
controllers must be switched off.
3.2 Commissioning
The room thermostats are delivered with a fixed set of applications and related
parameters. Select and activate the relevant application and settings during
commissioning using one of the following tools:
● Local DIP switches and HMI
● Synco ACS
● ETS5 or higher versions
● Siemens smartphone application PCT Go for Android
Set the DIP switches before snapping the thermostat to the mounting plate when
selecting an application via DIP switches.
Set all DIP switches to Off (remote configuration) when selecting an application via
commissioning tool.
After power is On, the thermostat resets and all LCD segments light up, indicating
that reset is correct. After the reset of 3 seconds, the thermostat is ready for
commissioning by qualified HVAC staff.
If all DIP switches are Off, NO APPL displays, indicating that application
commissioning via a tool is required.
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)
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.
To read or write settings, NFC must be activated on the smartphone and the phone
must be close to the NFC antenna (built into the thermostat), i.e. at a distance up
to ± 2 cm.

Connect the Synco ACS or ETS tools to the KNX bus cable at any point for
commissioning.
