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
qualifi ed technician. Before making any
connections, shut off electrical power
to the heat generator with its external
two-position switch. Power supply of the
device must beconnected to a circuit
breaker.
