Front panel with electronics, operating elements and built-in room temperature

sensor.

Mounting base with power electronics.

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 11 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

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

solar radiation. Mount about 1.5 m above the floor.

Mounting / Dismounting

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.

RDF301… : In case of limited space in the conduit box use the mounting

bracket ARG70.3 to increase the headroom by 10mm

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

Wiring See the mounting instructions M3171... enclosed with the thermostat.

Comply with local regulations to wire, fuse and earth the thermostat.

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 AC 230 V mains supply line must have an external fuse or circuit breaker

with a rated current of no more than 10 A.

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

conduit box carries AC 230 V mains voltage.

Inputs X1-M or X2-M of different units (e.g. summer/winter switch) 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 230 V

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

No metal conduits.

No cables provided with a metal sheath.

Disconnect from supply before opening the cover.

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 front panel 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 "NONE" to show that an application

needs to be set via tool.

Each time the application is changed, the thermostat reloads the factory setting for

all control parameters, except for KNX device and zone addresses!

ACS and ETS require an interface:

RS232 KNX interface (e.g. Siemens N148 / UP146 / UP152)

OCI700 USB- KNX interface

An external KNX bus power supply is required if an RDF301... / RDF600KN 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 P3171).

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 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 Y11/Y21 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.

Press buttons “operating mode” and “+” 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 RDF communication objects.

RDF301.50 has 2 switching groups with a pair of buttons each, which must be

configured via ETS. The switching groups only work on S-mode.

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

This device is classified as waste electronic equipment under European Directive

2002/96/EC (WEEE) and may not be disposed of as unsorted municipal waste.

Adhere to all relevant national laws.

Regarding disposal, use the systems setup for collecting electronic waste.

Observe all local and applicable laws.
