①FF: FF means that this setting has a corresponding dial switch on
the IDU PCB and the position of the switch determines the value of this
parameter.

on the main PCB and in case of no setting, the default value shall
prevail;
③ "The indoor unit fan stop time in heating mode" and the "Opening
Degree of EXV" are two mutually exclusive settings. The setting which
is done in the last would be effective. When set the heating EXV
standby position later , the indoor unit fan switching time will
automatically change to default value. When you set the fan stop time
later , the default EXV opening will change to 72 p automatically

simultaneously.
