Extension of semi flush-mounted room temperature
controller range
Introduction
2 years ago, Siemens introduced the first semi flush-mount room temperature controllers RDF310 and
RDF410. Customer feedback is very positive and sales volumes are exceeding expectations resulting in
the development of a range extension, which is now available as room temperature controllers
RDF300…, RDF340 and RDU340.
The new semi flush-mount room temperature controllers RDF (phase 2) come with the same stylish and
slim look & feel of the already introduced semi flush-mount RDF (phase 1), but with additional features
and benefits. These include additional applications and multifunctional inputs. This makes these new
products especially suitable for hotel guest rooms, offices and apartments.

New applications:
Fan coil units
2-pipe or 4-pipe on/off fan coil units / compressors in DX type equipment
2-pipe on/off and electric heater fan coil units / compressors in DX type equipment
2-pipe with 3-position valve fan coil units
VAV / CAV systems
Single-duct
Single-duct and electric heater
New main features:
Single- or 3-speed automatic or manual fan with advanced fan control function
2 multifunctional inputs for external sensor, keycard or contact switch, etc.
Modulating control outputs (DC 0…10 V signal)
Automatic or manual heating / cooling changeover
Temperature limitation for underfloor heating
Minimum and maximum limitation of air flow signal (DC 0…10 V output)
AC 230 V or AC 24 V operating voltage
The semi flush-mount room temperature controllers are designed to fit into an 86 x 86 x 47 mm conduit
box with fixing centers 60.3 mm (reference BS 4662 / IEC 60670). Optional conduit boxes (ARG71) are
also available as accessory items. Another accessory is the plastic mounting bracket (ARG70.3) for
conduit boxes with insufficient depth. The ARG70.3 mounting bracket is mounted between the wall and
the temperature controller to increase the headroom in the box by 10 mm.
Release of the next phase (phase 3) of the semi flush-mount room temperature controller range
extension is scheduled for the 3nd quarter of 2009 and will include variants with time program and
Konnex field bus communication.

Functions, features and benefits
Slim and stylish thanks to semi flush-mounted design
Features / functions
Benefits
The new semi flush-mounted room
temperature controllers offer a very slim,
modern and stylish look.
The ergonomic user interface with a large
display and push buttons make this
controller especially user-friendly.
A variant in silver is available as an option.
Backlit LCD (optional)
Features / functions
Benefits
The backlit LCD with soft blue color
improves readability in dark environments
and at night.
Display of setpoint or current room temperature
Features / functions
Benefits
As an alternative to displaying the current
room temperature, the RDF / RDU can be
configured to display the setpoint only.
This simplifies user operation and
particularly interesting for hotel rooms.
Current
room temperature
Concurrent display of degree C and F
Features / functions
Benefits
The room temperature controller can
display the temperature both in degree
Celsius and Fahrenheit. This is especially
helpful in hotels with guests from overseas.

Numerous applications in one model
Features / functions
Benefits
One model (ASN) offers numerous
applications easily selected via DIP switch.
This reduces the number of ASNs and
simplifies ordering and stocking.
Multifunctional inputs

Heating / cooling changeover sensor:
Automatic changeover for more
convenience
Operating mode switchover contact:
A useful function for hotel rooms with
keycard, commercial buildings with
time clock, etc. that helps save energy
when the specific area is not in use.
Dewpoint sensor input:
In connection with a dewpoint sensor
to prevent condensation and to avoid
damage to the building on chilled
ceiling applications.
Electric heater enable contact:
Enabling / disabling of electric heater
from remote for tariff regulation, energy
saving purposes, etc.
Fault input contact:
Digital input to signal faults and
maintenance reminder (e.g. filter
cleaning) to help extend the life of
equipment.

Single- or 3-speed fan control (automatically or manually)
Features / functions
Benefits
Automatic fan mode allows the room
temperature controller to automatically
vary the fan speed depending on setpoint
and current room temperature, thereby
improving comfort and saving energy.
Manual fan mode allows a constant fan
speed setting (low, medium, high) selected
by users based on their needs.
Clean fan filter reminder
Features / functions
Benefits
When the fan operating hours reach the
preset time, a “FIL” message
appears
on the display.
This reminder helps you carry out regular
maintenance on the fan coil unit.
Setpoint limitation
Features / functions
Benefits
Maximum and minimum setpoint limitation:
The adjustable range of the setpoint can
be limited. This is especially helpful in
public areas where energy consumption is
to be controlled, resulting in lower electrical
costs.
For example, the property manager can
set the minimum setpoint for cooling to
25 oC and the maximum setpoint for
heating to 18 oC in public areas of a
shopping mall or school. This allows for
better management of energy
consumption, thus reducing electrical
costs.

Temperature limitation for underfloor heating.
Features / functions
Benefits
Function for underfloor heating.
A floor temperature sensor, connected to
the multifunctional input, monitors the floor
temperature.
This function improves comfort and
protects the floor on applications with floor
heating
Keypad lock
Features / functions
Benefits
Keypad is locked.
Can be unlocked by
pressing the
operating mode
for
button
7 seconds
Automatic / manual lock of the keypad
helps prevent unauthorized readjustment
on the room temperature controller.
Adjustable control parameters
Features / functions
Benefits
Many control parameters can be adjusted
to meet individual needs. This gives high
flexibility and enables the controller to
adapt to any type of application.
Minimum output ON time / OFF time (compressor short cycle protection)
Features / functions
Benefits
The room temperature controller can
protect the compressor by limiting the
on/off switching cycle, thereby reducing
wear and tear and increase the lifetime of
the compressor. Simply speaking, we can
set a minimum on/off time via the control
parameters to control the opening and
closing actions if the user adjusts the
setpoint or heating / cooling mode
changeover incorrectly.

Important: Please verify to ensure the controller fits respective conduit box. The
controller requires at least 53 mm (W) x 68 mm (H) x 46 mm (D) for mounting in the
rectangular conduit box with fixing center 60.3 mm.
