I have a quick question on my TStat (for Trane XV95/XL15i system).
I had not focused on it because I have been distracted with static pressure and small duct issues.
I watched the Tstat (T803) yesterday and it was set at 75. It never moved off 75 as the AC cycled on and off every 6-10 minutes. I thought the compresser was only signaled to come on if the Tstat temp reading changed and thus a call was made to bring it back to the set point?
If I manually set it to 77 the compressor will go off and stay off until the room goes to 77 (even if it takes an hour or 2).
If I manually set it to 73 it will come on immedialtely and stay on until the temp gets to 73....then stay at 73 as the unit cycles on and off.
Can the unit be set less sensitive so that it only comes on if the temperature reading on the tstat goes above the set value a degree or 2?
I have no confidence in my installer as he originally under-wired, then mis-wirerd the tstat. It has been corrected thanks to this site. When he corrected it with the info I provided from this site he admitted he does not know much about these Tstats.
Thanks in advance.
