The display contains the following:
1) Normal display: On standby, the high position displays the
address of the outdoor unit, and the low position displays the Qty.
of indoor units that can communicate with the outdoor units. When
running, it will display the rotation frequency of the compressor.
2) Operation mode: 0-OFF; 2-Cooling; 3-Heating; 4-Constraint
cooling.
3) Fan speed: 0-stop; 1~15: speed increases sequentially; 15 is the
max. fan speed.
4) EXV opening angle: Pulse count=display value×8;
5) Priority mode: 0-heating priority mode; 1-cooling priority mode;
2-Number 63 and higher operating modes first; 3-responds to
heating mode only; 4-responds to cooling mode only.
6) Night noise control mode: 0-Night noise control mode; 1- silent
