No.8 Gray Not used Not used Local remote controller operation enable input

No.9 Red External DC source “+ 12VDC” or “+ 24VDC”

(A) For level signal

1 When the emergency stop/normal signal is selected, the status will switch from normal to emergency stop when the

external input signal contact changes from OFF to ON, and will change from emergency stop to normal when the contact
changes from ON to OFF. Air conditioning units that are stopped will remain off after the emergency stop is cancelled.
Start up each indoor unit to manually restore the previous operation.

2 When the ON/OFF signal is selected, the status will change from OFF to ON when the external input signal contact

changes from OFF to ON, and will change from ON to OFF when the contact changes from ON to OFF.

(B) For pulse signal

1 Even if the ON signal is input during ON, the status will remain ON.
2 If local remote controller operation is prohibited, the ON/OFF operation mode, temperature setting operations, and filter

reset from the local remote controller will be prohibited.

3 Set the pulse width (contact ON time) to 0.5 to 1 sec.
