I know this site is not for DIY advice, but can someone confirm whether or not this stat is properly wired? If not, maybe I can get my contractor to contact you, if you provide an email address or other contact information. The contractor is scheduled to return on Friday. The stat is a Honeywell TH8321U. It's hooked up to an Amana Ultron 16 SEER, RTG48C2C heat pump and the gas furnace is an Amana 96% AFUE, AMV90905DXA. For those interested in my never ending quest for a properly operating system you can check out the "Duel Fuel Heat Pump Operation" string and "Compressor Fan Question" string among others. A hardy thanks to all those kind enough to help.
