Description Of Rdf; Product Range Rdf/Rdu Stand-Alone; Product Range Rdf/Rdu Stand-Alone With Time Program; Product Range Rdf/Rdu With Bus Interface - Siemens RDG Series Application Manual

– RDG160 – the energy-effi cient 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-effi cient 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 fl ush-mount range
The RDF.. range is a compact semi fl ush mount solution. The RDF6.. line fi ts
into round conduit boxes with a 60 mm diameter and a minimum 40 mm of depth. The
RDF3.. and RDF4.. lines are designed to fi t into conduit boxes with fi xing 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.
