Outdoor unit (1) The model total of indoor units in the sys-
tem with one outdoor unit exceeds the fol-
lowing table.
1) Check the model total (capacity code total) of in-
door units connected.

connected indoor unit set by the switch (SW2 on
indoor unit board).
When the model name set by the switch is differ-
ent from that of the unit connected, turn off the
power source of the outdoor and the indoor units,
and change the setting of the model name (ca-
pacity code).

4) on the outdoor unit are set incorrectly.
Check the setting for the model selection switch
on the outdoor unit (Dipswitches SW5-1 - 5-4 on
the outdoor unit control board).

(OS) that is connected to the same system
are not properly connected.
Confirm that the TB3 on the OC and OS are
properly connected.
