TEV adjustment is chicken & egg.

Do you open the tev to get the duty from the evap to get the room temp or do you wait for the room temp to come down before opening it (which may never happen).

If the superheat is high and the room temp is high! where do you start??

You start by leaving the TXV adjustment alone. Don't even think about it. Adjusting a TXV is almost always a mistake. They do not get out of adjustment... unless somebody screws with them.

If the room temp is high, the superheat is supposed to be high. That's how a TXV works. If the room temp doesn't come down, then something else is wrong.

TXV's should be non-adjustable.
