Is that "Gas Temperature" the suction pipe temperature reading? Or is it the refrigerant saturated temp from a pressure transducer?

Hi sir
I'm ram, Form dubai
In My working site samsung vrf digital inverter, duct-table FCU have a problem since 4 months, vrf outdoor have 3 indoor units connect The problem is 3 FCU's fan moter speed not controlling in thermostat always running high speed in a month 1 and 2 days fan speed controling , we connect laptop tyred to control fan speed
1) we did three time programming
2)we changed fan mothers
3)we changed fan capacitor
4) we changed FCU pcb
5) we checked communication cable its proper condition
6) we changed fan control
7) we changed outdoor main pcb
8) we checked 3phase power with meger power normal condition
Plz give a suggestion ( I don't now the vrf system FCU fan speed why some days controlling some days control maybe fault from outdoor sensors because some days working some days not working)
Any error
@@BonMj No error sir
and Today started other 2 apartment same problem facing
(I note a point In UAE Since yesterday evening Too much humidity total Vrf units outdoors at night time sweating because of humidity) I can't understand

Hi sir, if one indoor fault ‘C4’ , all system will fault ‘u4’/‘u9’?
No
If many Fcu in one system, normally U9 Fcu are ok, check other fcu
