figure below.
É
The indication of "02" is turned ON
Ê
The address of the indoor unit which the optional
function is to be set, is indicated at the segments
for timer setting time indication, and the "ADDS" is
indicated below.
Ë
The refrigerant cycle number of the indoor unit for
the input and output setting is indicated at the
segments for timer setting time indication, and the
"RN" is indicated below.
Ì
The indication of the setting temperature is turned
OFF.
b. At the condition of the above item (a), press the
"TEMP
~
" switch or the "TEMP
}
" switch of the remote
control switch and the indoor unit for the input and output
