Need help from some real pro in Trane units. I live in Orlando area and tried 3 local hvac companies already - with no solution found.
The problem is that moisture in house is sometimes over 70% (summer of course). Even now (end of December it is around 45-50).
House has 3 XL19i units. Thermostat have option to control humidity but it isn't working (i think it is not wired).
When units are on humidity is going down. But units are powerful so they do not work for a long time to keep needed temperature. And when they stop working humidity is growing very fast.
One guy came and said that Trane units do not need wiring, they need some jumpers changed to fight moisture. He did it - nothing changed.
Second guy came and said that proper wiring should be made from thermostats to units so that TS can control humidity. Then he left to check how to do it and still is looking..
Third guy came and said that these units can not do anything for moisture and i need to understand why moisture is so high and fight things causing it but failed to find any himself.
So - if any of you DO know these Trane units - please help me! I will give any additional information if needed.
Thank you and Merry Chistmas and best wished to you guys in coming 2013!
