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.

Concurrent display of degree C and F

Features / functions Benefits

Showing the setpoint 24.5 oC and 76 oF simultaneously

The room temperature controller can

display the temperature both in degree

Celsius and Fahrenheit. This is especially

helpful in hotels with guests from overseas.

room temperature

32X049EN - April 2009 – HVAC Products 7

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

Features / functions Benefits

2 multifunctional inputs with freely

assignable functions:

oExternal / return air sensor for

temperature acquisition at an

alternative location

oHeating / cooling changeover sensor:

Automatic changeover for more

convenience

oOperating 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.

oDewpoint sensor input:

In connection with a dewpoint sensor

to prevent condensation and to avoid

damage to the building on chilled

ceiling applications.

oElectric heater enable contact:

Enabling / disabling of electric heater

from remote for tariff regulation, energy

saving purposes, etc.

oFault input contact:

Digital input to signal faults and

maintenance reminder (e.g. filter

cleaning) to help extend the life of

equipment.

32X049EN - April 2009 – HVAC Products 8

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.

32X049EN - April 2009 – HVAC Products 9

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

Automatic / manual lock of the keypad

helps prevent unauthorized readjustment

on the room temperature controller.

Adjustable control parameters

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.

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.

Keypad is locked.

Can be unlocked by

pressing the

operating mode

button for

7 seconds

32X049EN - April 2009 – HVAC Products 10

Easy to install

Features / functions

The temperature controller is fast-acting and easy to install: (1) wire, (2) mount and (3)

snap – no bothersome ribbon cable or dangerous opening with mains voltage.

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.
