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