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 fl ush-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
