In case the number of connected indoor units are more than 96, some AC cells should hold 2 or more indoor units.
4 In case of other central control like SC-SLxN-E is connected in the same network, the connectable indoor unit is limited up to 64 (32x2).
5 In case of previous Superlink protocol, the Superlink mode of new central control should be set "Previous".
6 In case of YES[A], previous central control is available to use. But the limitation of connectable indoor unit and so on is complied with
the rule of previous Superlink.
(3) The compatibility of PFD (refrigerant flow branching control)is mentioned in following table.
(4) Compatibility of the PFD control extension cables is as per the following table.

Superlink network, the dip switch of outdoor unit KXE6 of (YES [A]) should be set from (New) to (Previous).
In this case the Superlink protocol and limitation of outdoor unit system (YES [A]) are switched to Previous (for KX4).
