    low/high high/low



    Hi my Mr Slim control at fan low runs high and viceversa. If this simply means i use the switch as is with no problems then fine. But would it be more efficient or could there be a problem if i do this???
    It is a large ducted air con model PUH-3~6YK Thanks for looking

    Indoor fan Hi Low control via X1 and X2 relays, why low runs high?
    Something wrong somewhere. This is not correct .. but nothing relate to performance (of cooling or heating) but malfunctioning.
