Introd ction

The new thermostat range RDG and RDF is very versatile and consists of numerous

products. The RDG and RDF offer many new features and cover a broad ﬁeld of

applications.

This document shall:

– give you an overview of the new ranges RDG and RDF

– assist you by the selection of the suitable product, and

– provide you with helpful information for installation and commissioning

The section “application overview” for each main application – i.e. fan coil unit,

universal, heat pumps and VAV – shows what applications are covered by which

thermostat line.

The section “product overview” shows the available thermostat variants and their

supported applications.

Before you start

Before you start selecting a thermostat, we recommend to make the following

preselection:

– Type of main application: fan coil unit, universal, heat pump or VAV

– Application: e.g. 2-pipe with electrical heater

– Type of control output 1: ON/OFF, PWM, 3-position, or DC 0...10 V

– Type of control output 2: ON/OFF, PWM, 3-position, or DC 0…10 V

– Type of inputs: e.g. external room temperature sensor, changeover sensor,

key card switch etc.

– Type of thermostat: standalone, standalone with 7-day timer, or communicating

thermostat

– Thermostat design: wall- or semi flush-mounted

– Other important requirements

Description of RDG range

The RDG represents a compact wall-mounted version and is of elegant and modern design.

This range consists of 2 lines of versatile products – RDG100 line and RDG400 line:

– RDG100 line for fan coil units plus universal (e.g. chilled ceilings or radiators)

and heat pump applications

– RDG400 line for VAV applications

The thermostats are available as standalone versions, standalone with 7-day time program,

and NX versions tailored for use with Synco 700 via LTE-mode, for integration in Synco

living or BACS (building automation and control system) via S-mode.

Products range RDG

–RDG100 – the versatile standalone thermostat with ON/OFF and modulating

(PWM or 3-position) outputs

–RDG100T – the versatile standalone thermostat with 7-day time program and same

functionality as RDG100 plus infrared receiver for remote control

–RDG100KN – the versatile communicating thermostat with the same functionality as

RDG100 including NX interface

–RDG110 – the robust standalone thermostat with relay outputs (SPDT) for applications

with max. 5 A current on the control outputs. This thermostat is the ideal solution for

ON/OFF applications with electrical heater, heat pumps and heat pumps with reversing

valve (RV).

–RDG140 – the modulating thermostat operating on AC 24 V (SELV) with DC 0…10 V

control outputs.

–RDG160 – the energy efficient modulating thermostat for controlling of electronic

commutated fan motors (ECM Fan), operating on AC 24 V (SELV) with DC 0...10 V

outputs for valve and fan

–RDG400 – the versatile standalone thermostat for VAV applications with modulating

and ON/OFF outputs

–RDG400KN – the versatile communicating thermostat with the same functionality as

RDG400, including NX interface.

On each thermostat, a number of control parameters can be readjusted to optimize the

control performance.

Description of RDF semi flush-mount range

The range represents a compact semi-flush mount solution designed to fit into conduit

boxes with fixing center 60.3 mm (BSI standard BS4662).

The RDF and RDU are 2 lines of versatile and slim products:

– RDF line for fan coil unit and heat pump applications

– RDU line for VAV applications

The thermostats are available as standalone, standalone with 7-day time program and NX

versions tailored for use with Synco 700 via LTE-mode, for Synco living or for integration in

BACS via S-mode.

Products range RDF

–RDF300 – the versatile standalone thermostat with ON/OFF or modulating 3-position

outputs

–RDF400.01 – the versatile standalone thermostat with 7-day time program and

same functionality as RDF300, plus infrared receiver for remote control and backlit

digital display

–RDF301 – communicating thermostat with the same functionality as RDF300,

including NX interface and backlit digital display

–RDF301.50 – communicating thermostat with the same functionality as RDF301,

plus switching groups for lighting and blind control via NX S-mode

–RDF340 – modulating thermostat operating on AC 24 V (SELV) with DC 0…10 V

control outputs
