If several fan-coil systems are controlled by the same room thermostat, preference
should be given to motorized actuators with On/Off or 3-position control.

the selected actuators and to this list, depending on which value is lower:

Maximum number of actuators in parallel on the RDG100KN

Engineering notes

See the "Reference documentat ion", pa ge 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.

Siemens RDG100KN, RDG160KN Room thermostats with KNX communications CE1N3191en
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 swit ches.

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.

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:

ACS and ETS require an interface:

− 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

− Local HMI

− 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 housi ng.
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

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.
