Mounting and installation
Do not mount on a wall in niches or bookshelves, behind curtains, above or near
heat sources, or exposed to direct solar radiation. Mount about 1.5 m above the
floor.
Mounting
 Mount the room thermostat on a clean, dry indoor place without direct airflow
from a heating / cooling device, and not exposed to drips or splash water.
Wiring
See the mounting instructions M3192 enclosed with the thermostat.
 Comply with local regulations to wire, fuse and earth the thermostat.
 The power supply line must have an external fuse or circuit breaker with a rated
current of no more than 10 A.
 Isolate the cables of inputs X1-M, U1-G0 and D1-GND for 230 V if the conduit
box carries AC 230 V mains voltage.
 Inputs X1-M or D1-GND: Several switches (e.g. summer/winter switch) may be
connected in parallel. Consider overall maximum contact sensing current for
switch rating.
 Isolate the cables of KNX communication input CE+ / CE- for 230 V if the conduit
box carries AC 230 V mains voltage.
 No cables provided with a metal sheath.
 Disconnect from supply before removing from the mounting plate.
Commissioning notes
Applications
The room thermostat is delivered with a fixed set of applications.
Select and activate the relevant application during commissioning using one of the
following tools:
 Local DIP switch and HMI
 Synco ACS
 ETS3 Professional (planned)
Set the DIP switches before snapping the thermostat to the mounting plate, If you
want to select an application via DIP switches,.
All DIP switches need to be set to “OFF” ("remote configuration"), if you want to
select an application via commissioning tool.

After power is applied, the thermostat resets and all LCD segments flash, indicating 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 application commissioning via a tool is required.
Note
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:

ACS and ETS3 require an interface:
 RS232 KNX interface (e.g. Siemens N148 / UP146 / UP152)
 OCI700 USB-KNX interface
Note
An external KNX bus power supply is required if an RDG400KN is connected
directly to a tool (ACS or ETS3) via KNX interface.
Control parameters
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)
Control sequence
 The control sequence may need to be set via parameter P01 depending on the
application. The factory setting is “Cooling only”
Calibrate sensor
 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
Setpoint and setpoint
range limitation
 We recommend to review the setpoints and setpoint ranges (parameters
P08…P12) and change them as needed to achieve maximum comfort and save
energy

Programming mode
The programming mode helps identify the thermostat in the KNX network during
commissioning.
Press the left and right buttons simultaneously for 6 sec to activate programming
mode, which is indicated on the display with "PrOg".
Programming mode remains active until the identification of the thermostat is
complete.
Assign KNX group
addresses
Use ETS3 Professional to assign the KNX group addresses of the RDG communication objects,.
KNX serial Number
Each device has a unique KNX serial number inside of the plastic housing.
An additional sticker with the same KNX serial number is enclosed in the packaging box. This sticker is intended for installers for documentation purposes.
Disposal
This device is classified as waste electronic equipment under European Directive
2002/96/EC (WEEE) and may not be disposed of as unsorted municipal waste.
Adhere to all relevant national laws.
Regarding disposal, use the systems setup for collecting electronic waste.
Observe all local and applicable laws.
