The thermostats consist of two parts:
· Front panel with electronics, operating elements and built-in room temperature
sensor.
· Mounting base with power electronics.
RDF800KN/NF and RDD810KN/NF require additional mounting frames to
complete the installation and are only suitable for square conduit boxes (confirming
to BS 4662 standard).
RDF800KN is suitable for round conduit boxes (conforming to CEE/VDE), or
square conduit box (confirming to BS 4662 standard).
