Our old 7 day programmable kenmore themostat stopped

Customer Question

Our old 7 day programmable kenmore themostat stopped working. Replaced today with wifi 7 day honeywell rth9580, which runs but no coolong. Still89 degrees in house. Fan works. I set systm for heat pump and wired as close to old systm as could. I have a w1/o/b wire and a w2. Honeywell w2 also says aux backup, but I don't thi nk we have backup. Called honeywell but no help. How do I get to cool? Do I need to rewire? Thanks
JA: Did you double-check the thermostat's settings? And what about the filters?
Customer: Yes and changed filters. Honeywell guy on phone agreed with settings except did not know how to set the changeover because of backup/w2 wire question. I have connected wire but sais no backup in s
JA: Do you plan on doing the work yourself?
Customer: Ettings
