Engineering notes

See the "Reference documentation", page 12, 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

Mount the room thermostat on a conduit box. Do not mount on a wall in niches or

between bookshelves, behind curtains, above or near heat sources, or exposed to

direct solar radiation. Mount about 1.5 m above the floor.

Mounting / Dismounting

•Do not apply excessive force on screws! The deformation of the mounting

frame may lead to improper connections and operation of the unit.

•Mount the room thermostat on a clean, dry indoor place without direct airflow

from a heating / cooling device, and not exposed to drips or water.

•Before removing the front cover, disconnect the power supply.

Wiring See the User Manual for the installation instructions 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.

•The wiring cross section used for power supply (L, N) and 230 V outputs

(Qxx - N) must be adapted to the preceding overload protection elements (max

10 A) under all circumstances. Comply under all circumstances with local

regulations.

•Properly size the cables to the thermostat and valve actuators for

AC 230 V mains voltage.

•Cables of SELV inputs X1-M / X2-M: Use cables with min 230 V insulation, as

the conduit box carries AC 230 V mains voltage.

•Inputs X1-M or X2-M of different units (e.g. window contact) may be connected

in parallel with an external switch. Consider overall maximum contact sensing

current for switch rating.

•KNX communication cables (input CE+ / CE-): Use cables with min 230 V

insulation, as the conduit box carries AC 230 V mains voltage.

•When a KNX bus power supply is connected on the line with communicating

thermostats and Synco controllers, the internal KNX power supply of the

Synco controllers must be switched off.

•No cables provided with a metal shield.

•Disconnect from supply before opening the cover.

RDD810KN… thermostats are for heating applications. Configure or changing

parameter settings during commissioning using one of the following tools:

−Local HMI

−Synco ACS

−ETS4

Connect the Synco ACS or ETS4 tools to the KNX bus cable at any point for

commissioning:

ACS and ETS4 require an interface:

−RS232 KNX interface (such as Siemens N148 / UP146 / UP152)

−OCI700 USB-KNX interface

An external KNX bus power supply is required if an RDD810KN/NF is connected

directly to a tool (ACS or ETS4) via KNX interface.

The thermostat's control parameters can be set to ensure optimum performance of

the entire system (refer to basic documentation P3174).

The parameters can be adjusted using

−Local HMI

−Synco ACS

−ETS4

For commissioning via local HMI, refer to user manual B3174... for setting the

passwords.

•Only heating sequence is available.

•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 heating setpoint and their range limitation via

parameters P08…P11. If necessary, adjust them to achieve maximum comfort

and save energy.

The programming mode helps identify the thermostat in the KNX network during

commissioning.

Touch and hold

for more than 5 seconds to activate programming mode, which

is indicated on the display with Pr09. Programming mode remains active until

thermostat identification is complete.

Assign device address (P81) via HMI, ACS or ETS4.

With device address set to 255, the communication is deactivated (no exchange of

process data).

Use ETS4 to assign the KNX group addresses of the RDD communication objects.

Each device has a unique KNX serial number inside the front panel. 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.
