1. Terminal numbers of outdoor and indoor units must be
matched.
2-1. Connect the remote controller only to the master unit.
2-2. The remote controller needs to be wired only to the mas-

units through transition wiring. (Do not connect transition
wiring to the slave units.)
2-3. The indoor temperature sensor is effective only for indoor
units to which the remote controller is connected.
2-4. The length of wiring between the indoor unit and the out-
door unit varies depending on the connected model, the
number of connected units, and the maximum piping
length.
