[1] When operating on High ( Extra High ) fan speed via external input
Usually, ventilation is performed at Low fan speed, and there is automatic switching to High ( Extra High )
fan speed when dirty indoor air is detected by a CO
Insert the remote display adaptor ( PAC-SA88HA-E ) into the connector ( CN16 ) on the Lossnay circuit
board, and input the signal ( uncharged a-contact ) from a CO
