Hi Anil130
What model indoor unit?
If the Indoor PCB has CNS connector socket you can use SC-BIKN-E interface and CNT connector harness. The external input can be configured as Permission/Prohibition which will allow operation of AC when keycard closes contact and stop and disable AC operation when external input is opened.
