1 indoor unit,
and also in a system where 1 outdoor unit is connected to

(maxim
um 4).
•
If link wiring is used, set the outdoor unit system address to allo

units to be identi ed. At the same time, indicate the indoor-outdoor unit combination number in a location
where it can be chec
ked easily (near the indoor unit nameplates
)
