2. Set the R.C. address. (Function setting)
• Addresses will be automatically set when initially starting up this unit. In such a case, do
not change the remote controller address for the indoor unit, and keep it at the initial set-
ting of “00”.
• Only set addresses manually when using different numbers for addresses.
Set the R.C. address of each indoor unit using the function setting. (Refer to “Remote con-
troller address setting” in
"Contents of function setting"
on page 35.)
NOTES:
– Do not use the same setting value.
– Setting is reflected after the power is turned on again.
Also set the R.C. address for the remote controller. For details, refer to the remote con-
troller installation manual.
NOTE:
In manual setting, connect up to 15 indoor units in a system.
