Ordering

When ordering, indicate product number, SSN and name.
For example: RDD810KN/NF (S55770-T336) room thermostat
A mounting frame must be ordered for RDD810KN… installation (See “Accessories”)
Order valve actuators separately

Equipment combinations

Accessories

Mechanical design

The thermostats consist of the following parts:

Front panel with electronics, operating elements and built-in room temperature sensor.
Mounting base with power electronics.
Mounting frame is an additional part to complete the installation for RDD810KN….

Operation and settings

Display

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 the 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, protect and earth the thermostat.
The device has no internal fuse for supply lines to fans and actuators. To avoid the 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 the 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 the 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 are provided with a metal shield.
Disconnect from supply before opening the cover.

Commissioning notes

Before power up: No DIP switch setting is required for RDD810KN… thermostats.

Wizard function: After powering up, the wizard function guides users to configure the basic parameters for normal operation according to the table below.

Touch to advance/return to any parameter;
Touch + / – to change the value.

Applications

RDD810KN… thermostats are for heating applications. Configure or change parameter settings during commissioning using one of the following tools:

Local HMI
Synco ACS
ETS5

Connect tool

Connect the Synco ACS or ETS5 tools to the KNX bus cable at any point for commissioning ACS and ETS5 require an interface:

Ethernet/LAN KNX interface (such as Siemens N148 / N146 / N152)
OCI702 USB-KNX interface

Control parameters

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
ETS5

Control sequence: Only heating sequence is available

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 range limitation: We recommend reviewing heating setpoint and their range limitation via parameters P08…P11. If necessary, adjust them to achieve maximum comfort and save energy

Programming mode: 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. The programming mode remains active until thermostat identification is complete.

Assign KNX device address: Assign device address (P81) via HMI, ACS or ETS5. With the device address set to 255, the communication is deactivated (no exchange of process data).

Assign KNX group addresses: Use ETS5 to assign the KNX group addresses of the RDD communication objects

KNX serial number: 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 device is considered electrical and electronic equipment for disposal in terms of the applicable European Directive and may not be disposed of as domestic garbage.

Dispose of the device through channels provided for this purpose.
Comply with all local and currently applicable laws and regulations
