RDF range – for semi fl ush mounting with time programs for
fan coil units, also available with KNX communication
RDF301.50 – communicating room thermostat with
lighting and blinds control
High level of flexibility and cost
efficiency thanks to consistent
product concept
The new room thermostats are suited for
a host of applications, including fan coil
units, variable air volume systems, chilled
ceilings, heating systems and heat
pumps. This means that plants operating
on different heating and cooling systems
can make use of a consistent design con-
cept based on uniform operation. Instal-
lation and commissioning are quick and
economical since the room thermostats
use the same product concept. Employ-
ing KNX – the only open, global standard
on home and building management –
the communicating thermostats can
be seamlessly integrated into existing
systems. The devices are available with
Modbus communication as well.
Flexibility and efficiency are also offered
by the choice of connection facilities for
external sensors and contacts. For exam-
ple, in hotels, the room thermostats in
connection with a keycard contact auto-
matically switch to energy saving mode
when the guest leaves the room. To
ensure accurate acquisition and control of
the room temperature, an external room
temperature sensor can be connected.
Through changeover sensors, the plant is
automatically switched from heating to
cooling and vice versa. As the RDG room
thermostats are wall-mounted, they can
easily be fitted in a suitable place.
Top-quality that pays off in the
long term
Long service life and a high level of reli-
ability of the room thermostats ensure
efficient operation. This means that you
benefit from your investment not only
in the short term, but for many years to
come, backed by meticulous production,
top-quality materials and comprehensive
quality management.
