5. Install sensor for Devireg™ 530 and 532
The floor sensor should be mounted in a 6.7 mm
installation pipe which is sealed at the end to prevent
penetration of concrete into the pipe. Minimum
bending radius for the pipe is 50 mm.
The sensor cable must be placed in between two
strings of the heating cable.
To avoid cracks in the concrete floor you must ensure
that the floor is completely hardened before the heat
is switched on.
If a floor sensor is used, it is recommended to install
it inside an insulating conduit, sealed at the end in the
floor, enabling easy replacement of the floor sensor if
required. If installed without a conduit, the floor
sensor must be installed so that it is inaccessible and
not in contact with any conductive building parts.
If the supplied floor sensor is too short, longer ones
can be purchased from you local DEVI supplier or it
can be extended with proper materials.
The floor sensor is a LIVE cable; therefore any
extension made to the sensor wiring should be
treated as for normal mains voltage cabling.
