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

RDF800KN/NF.

The rear of the mounting base contains the screw terminals. Slide the front panel in the mounting base and snap on.

Engineering notes

See the "Reference documentation", page 15, 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 expose to drips or splashes water.

• For RDF800KN only, in case of limited space in the conduit box, use the mounting spacer ARG70.3 to increase the headroom by 10mm.

• 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.

• 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 / relays (Qx) and 230

V outputs (Yx - N) must be adapted to the preceding overload protection elements (max 10A) under all circumstances. Comply under all circumstances

with local regulations.

• 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: Several switches (e.g. window contact) may be connected in parallel. 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.

Commissioning notes

Set DIP switches to select the desired application before power up:

1. For remote setup via commissioning tools, set all DIP switches to OFF (see "Remote configuration" for more details);

2. For local setup, set DIP switches to select applications (refer to the following table).

If more details are required about parameters, refer to basic documentation P3174.

To re-load factory settings for all parameters, set parameter P71 to ON. Restart the thermostat after reset, all LCD segments flash, indicating that the reset is correct. 3 seconds later, the thermostat is ready for commissioning by qualified HVAC staff.

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

− ETS4

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.

• The control sequence may need to be set via parameter P01 depending on the

application. The factory setting for the 2-pipe application is "Cooling only"; and "Heating and Cooling" for the 4-pipe application.

• When the thermostat is used with a compressor, adjust the minimum output on-

time (parameter P48) and off-time (parameter P49) for Y1 / Y2 to avoid damaging the compressor or shortening its life due to frequent switching.

• 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.

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 RDF 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.
