I have a Trane XL19i 5 ton split heat pump with strips, live in north east MS with a Vision Pro IAQ T stat. I want the first stage on A/C to run the max amount of time to get the moisture out of the air currently 95f 67 % humidity outside, 72f 57% humidity inside. Water is a constant drip on the drain and I have a dehumidifier running inside that I empty 1-2 times every 24 hrs. House has crawlspace with vapor barrier on ground, duct work is in attic. The unit is constantly switching low / high / low / high......and I know the switching is killing my electric usage. Any help is appreciated.

Thanks,
Jimmy

In the installer set up menu, what is 220, and 230 set to?

Is 370 set to 1?

379 set to 1?

Do you know if dehum from the EIM wired to BK on the air handler?

Try 230 at 1, and see what happens.

Also maybe 690 to 1.

Yeah, let the t-stat readjust itself after a few days.
