Hi, can I ask if anyone can explain how my trane 802 thermostat controls (zone panel set to thermostat control) the staging of my new trane 20i two stage air conditioner. I've read the manual, and done a brief internet search. I'm happy with the unit (and appreciate the forum convincing me not to upsize).
1. Early morning the temp reading was 76, first stage cooling started, and ran in the 10-15 minutes. "inside temp" stayed at 76 the entire time. The stat senses less than a ½ degree difference? Do I want it this sensitive?
2. 79 in house, turned on AC. Second stage 2 hours (89 degrees outside), inside temp back to 76, then the stat dropped down to first stage for about 45 minutes (inside temp said 76 the whole time). It somehow calculated the rate of fall in temp, and it was 76.4, and the stat know first stage would be enough to 76.0?
My final question---are any of the parameters user controllable (why would I want to change them is another question of course)?
