S31/S32 displays “U019”, which is used to set DA1 function
When U001=2,3
U019=0, fan control signal is based on Tr, Ts PID calculation
U019=1, fan control signal is based on ESP PID calculation
S31/S32 displays “U020”, which is used to calibrate the sensor on the wired wall pad.
-5~5, default: -3
S31/S32 displays “U021”, which is used to set EH function
U021= 0, without EH.
U021= 1, EH as booster.
U021=2, EH as primary.
S31/S32 displays “U022”, which is used to select Tr sensor.
0=the sensor in the WWP.
1=the sensor in the PCB.
S31/S32 displays “U023”, which is used to display cooling and heating energy consumption.
0=S34/S35/S36/S37 disappears
1=S34/S35/S36/S37 appears
In cooling and dehumidification mode, cooling energy consumption is shown.
In heating mode, heating energy consumption is shown.
2=Motor running time is shown.
S31/S32 displays “U024”, which is used to set low speed RPM or control signal.
S31/S32 displays “U025”, which is used to set medium speed RPM or control signal.
S31/S32 displays “U026”, which is used to set high speed RPM or control signal.
S31/S32 displays “U027”, which is used to set Delta T OF Ti1/Ti2.
S31/S32 displays “U028”, which is used to set Delta T OF Ti3/Ti4.
S31/S32 displays “U029”, which is used to read unit type.
S31/S32 displays “U030”, which is used to read unit model.
S31/S32 displays “U031”, which is used to read unit manufacturing date.
