I just wanted to say thank you to all who responded to my questions and to those who continued to respond until I notified them it was fixed. It's nice to know there is people out there who really do care. I passed on all your helpful questions to our AC guy and I believe he checked the wiring at the heat pump to make sure it was wired properly the second time he was out at our house because that is what one of the posts told me to tell him. I'm not so sure he would have checked that since it was a new install in Jan. and worked fine until we needed our AC and it reached over 100. We are nice and cold in hot Phoenix now.
I still want a thermostat that doesn't cost me my right arm and that is programmable that tells me when the heat pump is in stage 2 while cooling it only tells me stage 2 when in heating mode. It could have saved the repair guy from coming out 3 times.
