CNT connector functions
Turning the contacts ON/OFF, the off/running status of the air conditioner can be monitored from the External control unit (remote display).
1Connect a locally procured remote control
unit to the CNT terminal.
2In case of the pulse input, cut off the
jumper wire "J1" on the main unit PCB.
3When setting at Operation
permission/prohibition Mode, cut off the
jumper wire "J3".
