Connect the Synco ACS or ETS tools to the KNX bus cable at any point for
commissioning:
KNX
X1 M X2 CE+ CE-
Y11
ACS and ETS require an interface:

RS232 KNX interface (e.g. Siemens N148 / UP146 / UP152)

OCI700 USB- KNX interface
An external KNX bus power supply is required if an RDF301... / RDF600KN is
connected directly to a tool (ACS or ETS) via KNX interface.
The thermostat's control parameters can be set to ensure optimum performance of
the entire system (see basic documentation P3171).
The parameters can be adjusted using

Local HMI

Synco ACS
 ETS
 The control sequence may need to be set via parameter P01 depending on the
application. The factory setting for the 2-pipe application is "Cooling only"; and
"Heating and Cooling" for the 4-pipe application.
 When the thermostat is used with a compressor, adjust the minimum output on-
time (parameter P48) and off-time (parameter P49) for Y11/Y21 to avoid
damaging the compressor or shortening its life due to frequent switching.
 Recalibrate the temperature sensor if the room temperature displayed on the
thermostat does not match the room temperature measured (after min. 1 hour of
operation). To do this, change parameter P05.
 We recommend to review the setpoints and setpoint ranges (parameters
P08...P12) and change them as needed to achieve maximum comfort and save
energy.
The programming mode helps identify the thermostat in the KNX network during
commissioning.
Press buttons "operating mode"

Programming mode remains active until thermostat identification is complete.
