After power is applied, the thermostat resets and all LCD segments flash, indica-
ting that the reset was correct. After the reset, which takes about 3 seconds, the
thermostat is ready for commissioning by qualified HVAC staff.
If all DIP switches are OFF, the display reads "NO APPL" to indicate that appli-
cation commissioning via a tool is required.
Each time the application is changed, the thermostat reloads the factory setting for
all control parameters, except for KNX device and zone addresses!
Connect the Synco ACS or ETS3 Professional tools to the KNX bus cable at any
point for commissioning:
KNX
U1 D1 GND
X1 M CE+ CE-
Y10
Y1 Y2
ACS and ETS3 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 RDG400KN is connected
directly to a tool (ACS or ETS3) via KNX interface.
The thermostat's control parameters can be set to ensure optimum performance of
the entire system (see basic documentation P3192).
The parameters can be adjusted using

Local HMI

Synco ACS
 ETS3 Professional (planned)
 The control sequence may need to be set via parameter P01 depending on the
application. The factory setting is "Cooling only"
 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
