NOTES:
• When the rotary switch is selected to “1", the operation of the connector input of the indoor
unit and the External Input and Output PCB input are the same. The operation content de-
pends on the setting of function setting number 46.
• *1: The external input other than “Operation/Stop” is available only when the SW302 is set to
“Edge”.
• *2: The external input of “Mechanical cooling on” is available only when the function setting
number 60 is set to “03” or “04”.
