You guys were a great source of information in choosing my system! I would like opinions on the following setup & initial run.
My new 3-day-old Trane system is XL14i HP, XV80 2-stage furnace and VisionPro 8321 stat. Contractor installed a Trane Heat Pump Kit (TAYPLUS130A) and set the stat as 2 heat/1 cool (170 = 7) with electric backup (200 = 0). The outdoor sensor is set to display (210 not displayed & 340 = 1). I am in Atlanta GA.
I have 3 questions:
Do you think this configuration is better than/as good as 3 heat/2 cool with no HP kit? Company owner (in business for over 30 years) says this is the most economical setup and his house has the HP kit.
Thursday was our first night night in the 30's. Recovering from a 4 degree set back (68 to 64) on Wake schedule, the system ran what I think is a short cycle. The HP ran 4-5 minutes, then AUX ran for 2 minutes and this cycle repeated until the temp was within 1 degree of the set point - then no more AUX until shutoff. Is this a short cycle? Is it caused by the stat set for 2/1 with electric backup?
The contractor has been given this same information. I will not change anything myself, but I like to have good information.
