[1-10]= shows the total number of connected indoor units.
It can be convenient to check if the total number of indoor
units which are installed match the total number of indoor
units which are recognized by the system. In case there is a
mismatch, it is advised to check the communication wiring
path between outdoor and indoor units (F1/F2 communica-
tion line).
[1-13]= shows the total number of connected outdoor units (in case
of multiple outdoor system).
It can be convenient to check if the total number of out-
door units which are installed matches the total number of
outdoor units which are recognized by the system. In case
there is a mismatch, it is advised to check the communica-
tion wiring path between outdoor and outdoor units (Q1/Q2
communication line).
