E02Remote detecting error from indoor unit,
E03Indoor unit detecting error from remote,
E04Indoor seeing error from outdoor. Qty of i/d units connected are less than qty set. Check; all i/d units are ON, reset turn off all units wait 5min power up
E05Indoor unit detecting error from outdoor unit, Error in sending comms signal
E06Outdoor unit detecting error from indoor unit, Error in receiving comms signal
E07Outdoor unit detecting error from indoor unit, Error in sending comms signal
E08Incorrect setting indoor/controller, Indoor address duplicated
E09Incorrect setting indoor/controller, Remote address duplicated or IR wireless controller not disabled
E10Indoor unit detecting error from 'option' plug, Error in sending comms signal
E11Indoor unit detecting error from 'option' plug, Error in receiving comms signal
E12Auto addressing failed,Auto address connector CN100 shorted during auto addressing
E13Indoor unit failed to send signal to remote controller
E14Setting Failure, Duplication of master indoor units
E15Auto addressing failed, Number of indoor units connected are less than number set
E16Auto addressing failed, Number of indoor units connected are more than number set
E17Group control wiring error, Main indoor unit not sending signal for sub indoor units
E18Group control wiring error, Main indoor unit not receiving signal for sub indoor units
E20Auto addressing failed, No indoor units connected
E24Auto addressing failed, Error on sub outdoor unit
E25Auto addressing failed, Error on outdoor unit address setting
E26Auto addressing failed, Quantity of main and sub outdoor units do not correspond to the number set on main outdoor unit P.C.B.
E29Auto addressing failed, Sub outdoor unit not receiving comms for main outdoor unit
E31Between units, Comms failure with MDC, does E31 remain after power is re instated? If so replace PCB. & power
