Here is how
1. Connect power cable.
2. Plug in communication cable between com-
munication module and Air unit.
The cable cannot be fitted wrongly.
Important
If the communication module is mounted in
different floor than wireless remote, please check
if the deck construction contains elements that
will reduce transmission/receiving strength (i.e.
aluminum foil clad insulation material, or metal
grid, if deck is cast in concrete). If any such distur-
bances are present, the communication module
should be placed in same floor as wireless remote
control.
If an ethernet connection is already available in
the vicinity of the Air unit, place the communi-
cation module close to this, to allow for future
connection to PC.
