Answer
Hi William -

Yes, now I understand what is happening. I was a bit confused.

Now, have you taken the pressure readings? This is an important component of the process, to see if there is a difference in pressure when you go to speed 4, as opposed to the other speeds. Please take them and let me know.

So, when you set the fan speed on 3, 2 or 1, it will cool all the time (meaning no short cycling, no cut off), as long as you don't switch it to speed 4?

thanks
