TRANSMISSION LINE SEPARATION RULES
●
The transmission line between indoor unit, outdoor unit and controllers can be connected by
one cable.
●
Terminal board available on the market or the ones inside the indoor unit or outdoor should
be used for transmission line separation.
●
Connection of three or more lines may cause poor communication for one terminal. In this
case, use a terminal box.
Note
● Do not loop.
