Ahh for the slow to start it is normal. Theres a random delay timer so if you have 10 air conds to turn on they will not ALL kick in simultaneously lest your main MCB tripped coz the point of motor start takes up the most current (Imax). DB box can handle one Imax at a time easily but not 10 Imax at the same time.

Yes. I think is the sensor that is delaying the fan start up.

I think the delay is normal. I have 4 units of CS-U at home and behave the same. Cannot be I have 4 faulty units right?

Sorry for the delay in reply. With remote in Off :

1) Briefly press the small Set button beside clock button (you will see something like 1 A)
2) Use temperature up / down and cycle to function 14
3) Use the Select up/down button to set swing position during auto swing (the diagrams for the swing position are self explanatory on the remote. rT cT and lT)
4) Once selected, point the remote at the air con and press the SET button (timer section). You will hear the /c beep once
5) Leave the remote alone and it will go back to the main screen.

I am just guessing that it will let the refrigerant travel fully to the coils first, before blowing out the cool air.

Coming from SxxMKH, SxxTKH, XUxxUKH, XUxxVKH and XUxxXKH all also same behaviour when fan speed is set to Auto on cool or dry mode.
