Introduction
The RDG and RDF thermostat range is very versatile and includes a number of products.
RDG and RDF offer extensive features and cover a broad range of applications.
The document:
– provides you an overview of the new RDG and RDF ranges
– assists you in selecting the suitable product and
– provides helpful installation and commissioning information
The section “application overview” for each main application – i.e. fan coil unit
(FCU, universal, heat pumps and VAV – shows what applications are covered by
which thermostat line.
The sections “product overview” show the available thermostat variants and their
supported applications.
Before you start
We recommend proceeding as follows prior to selecting a thermostat:
– Type of main application: FCU, universal, heat pump or VAV
– Application: e.g. 2-pipe with electric 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,
keycard contact etc.
– Type of thermostat: stand-alone, stand-alone with 7-day timer, or communicating
thermostat
– Thermostat design: wall- or semi flush-mounted
– Other important requirements
Description of RDG range
The RDG is a compact, wall-mounted version with an elegant and modern design.
The product consists of 2 lines of versatile products – RDG100 and RDG400:
– RDG100 line for FCUs plus universal (e.g. chilled ceilings or radiators)
and heat pump applications
– RDG400 line for VAV applications
The thermostats are available as stand-alone versions, stand-alone with 7-day program
and KNX 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.
Product range RDG
– RDG100 – the versatile stand-alone thermostat with ON/OFF and modulating
(PWM or 3-position) outputs
– RDG100T – the versatile stand-alone thermostat with 7-day program and same
functionality as RDG100, plus infrared receiver for remote control
– RDG100T/H – the versatile stand-alone thermostat is the landscape version of RDG100T,
the 7-day program can be disabled
– RDG100KN – the versatile communicating thermostat with the same functionality as
RDG100, plus KNX interface
– RDG110 – the robust stand-alone 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 electric heater, heat pumps, or heat pumps with reversing
valve (RV).
– RDG140 – the modulating thermostat operating on AC 24 V (SELV) with DC 0…10 V
control outputs

5
– RDG160 – the energy-efficient modulating thermostat to control electronic
commutated fan motors (ECM Fans), operating on AC 24 V (SELV) with DC 0...10 V
outputs for valve and fan
– RDG160KN –the communicating energy-efficient modulating thermostat for control-
ling electronic commutated fan motors (EC Fans) and either DC or 2-position valves, or
for 3-speed fan and DC valves, including KNX interface
– RDG400 – the versatile stand-alone thermostat for VAV applications with modulating
and ON/OFF outputs
– RDG400KN – the versatile communicating thermostat with the same functionality as
RDG400, plus KNX interface
A number of control parameters can be adjusted on each thermostat to optimize the
control performance.
Description of RDF semi flush-mount range
The RDF.. range is a compact semi flush mount solution. The RDF6.. line fits
into round conduit boxes with a 60 mm diameter and a minimum 40 mm of depth. The
RDF3.. and RDF4.. lines are designed to fit into conduit boxes with fixing center 60.3 mm
(British standard BS4662).
The RDF and RDU are two product ranges featuring versatile and slim products:
– RDF range for FCUs and heat pump applications
– RDU range for VAV applications
The thermostats are available as stand-alone, stand-alone with 7-day program and KNX
versions tailored for use with Synco 700 via LTE-mode, for Synco living or for integration in
BACS via S-mode. There is also a version available with ModBus interface.

How to prepare and set up
your room thermostats
Introduction
The versatile RDG and RDF room thermostats help you to better meet your customer‘s needs.
The following information supports you in setting up your RDG and RDF thermostats.
Control parameters
A number of control parameters can be adjusted to optimize control performance and
enable additional functions, making it possible to employ. The RDG and RDF thermostats
in almost any type of application.
The control parameters are assigned to 2 levels:
– Service level and
– Expert level
The service level contains a small set of parameters to set up the thermostat for HVAC
systems (control sequence) and to adjust the user interface.
The expert level contains control parameters for fan, control inputs/outputs and other
functions. Take care when changing parameters on the expert level as these changes
impact the thermostat‘s control performance and functionality.
As a rule, you don´t need to adjust parameters once the required application is selected
via the DIP switch since the thermostat works correctly using factory set parameters. It may
be nevertheless necessary, in some cases, to adjust application specific parameters.
– Control sequence (P01): select heating/cooling sequence and
changeover function
– Multifunctional inputs (P38…P42): select the input functionality for X1, X2 and D1
– Control outputs (P46…P47): select type of output signal (ON/OFF, PWM, 3-pos.)
– Fan function (P52...P62): select fan functionality
Installation and set up
1. Select a suitable thermostat.
2. Set application via DIP switch as per mounting instructions.
3. Wire and install the thermostat. Apply power.
4. Set parameter P01 (control sequence) and other
application-specific parameters as needed.
Note: ARG71 – conduit box suitable for RDF3.. and RDF4.. semi flush-mount thermostats is
available as an accessory item.
