Engineering notes
See the "Reference documentation", page 17 for information on how to engineer
the KNX bus (topology, bus repeaters, etc.) and how to select and dimension
connecting cables for supply voltage and field devices.
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 M3191 enclosed with the thermostat.
•Comply with local regulations to wire, protection and earth the thermostat.
•The device has no internal fuse for supply lines to fan and actuators. To avoid
risk of fire and injury due to short-circuits, the AC 230 V mains supply line must
have a circuit breaker with a rated current of no more than 10 A.
•Properly size the cables to the thermostat, fan and valve actuators for AC
230 V mains voltage.
•Use only valve actuators rated for AC 230 V.
•The wiring cross section used for power supply (L, N), fan (Q1, Q2, Q3, N) and
230 V outputs (Yx - N) must be adapted to the preceding overload protection
elements (10A) under all circumstances. Comply under all circumstances with
local regulations.
•Isolate the cables of input D1-GND for 230 V if the conduit box carries AC
230 V mains voltage.
•X1-M, X2-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.
•Inputs X1-M and X2-M carry mains potential (RDG100KN only).
Sensor cables must be suited for AC 230 V mains voltage
•Selectable relay function (RDG160KN): Follow instructions in P3191 to connect
external equipment to the relay outputs.
•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.
•When a KNX bus power supply is connected on the line with communicating
thermostats and Synco controller, the internal KNX power supply of the Synco
controllers must be switched off.

Building Technologies 2014-05-23

Commissioning notes
The room thermostats are 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
−ETS
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, 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
application 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 ETS tools to the KNX bus cable at any point for
commissioning:

−OCI700 USB- KNX interface
An external KNX bus power supply is required if an RDG1...KN 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 P3191).
The parameters can be adjusted using

−Synco ACS
−ETS

•The control sequence may need to be set via parameter P01 depending on the
application. The factory setting is as follows:
Application
Factory setting P01
2-pipe and chilled / heated ceiling, and 2-stage
1 = Cooling only
4-pipe, chilled ceiling and radiator
4 = Heating and cooling
•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 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 thermostat identification is complete.
Use ETS to assign the KNX group addresses of the RDG communication objects.
Each device has a unique KNX serial number inside the plastic housing.
An additional sticker with the same KNX serial number is enclosed in the packa-
ging box. This sticker is intended for installers for documentation purposes.
Disposal
The devices are considered electronics devices for disposal in terms of European
Directive 2012/19/EU and may not be disposed of as domestic waste.
•Dispose of the device via the channels provided for this purpose.
•Comply with all local and currently applicable laws and regulations.
