Thin mats
Symbol description referring
Direct floor heating:
• Thin mats must always be controlled by
a thermostat that limits the floor tem-
perature to max. 35 °C (DEVIreg™ Smart,
DEVIreg™ Touch, DEVIreg™ Opti or
DEVIreg™ 530M).
• Never exceed the maximum heat density
(W/m) for the actual application.
• In case of a wooden subfloor, the maxi-
mum installed output is 100 W/m².
• On concrete subfloor the maximum of
200 W/m² is allowed if: the thickness of
the concrete covering above the heating
element, is more than 4 cm (40 mm).
• Thin mats are not to be interconnected.
• All thin mats in the same room must
have the same heat density (W/m2)
unless they are connected to separate
floor sensors and thermostats.
• The enclosed label must be filled in
and placed adjacent to the distribu-
tion board, describing location of the
thin mat.
• If supply cord is damaged it must be
replaced by the manufacturer, its service
agent or similarly qualified persons in
order to avoid hazard.
The presence of a thin mat must
• be made evident by affixing caution
signs in the fuse box and in the distribu-
tion board or markings at the power
connection fittings.
• be stated in any electrical documenta-
tion following the installation.
