installing the cabled version (3319116)
Positioning
The device detects the room tempera-
ture, therefore several factors should be
taken into account when choosing an in-
stallation site. Position the device far from
heat sources (radiators, sunlight, fi replac-
es, etc.) and from draughts, doorways
and windows which could aff ect the tem-
perature readings. It should be installed
approximately 1.5 metres above the fl oor
level.
ATTENTION!
Installation should be performed by a quali-
fi ed technician. Before making any connec-
tions, shut off electrical power to the heat
generator with its external two-position
switch. Power supply of the device must be-
connected to a circuit breaker.
