After calling the installer, I was told to look for the manual for Honeywell 8000 8320 thermostat. I can't find that one on your site and consequently am not able to properly set our thermostat to keep us cool here in Texas. Please direct me to the correct thermostat. I was told that I had a Honeywell 8000 thermostat and that the 8320 was just to narrow it down...thanks
