CAN YOU TELL ME HOW TO FIND IT? I KNOW THAT IT IS AN OLDER ONE, ABOUT 16 YEARS OLD. I ABSOLUTELY HATE THIS ONE WE HAVE ANOTHER ONE THAT IS YEARS NEWER BUT WE WERE TOLD THAT IT IS ONLY A SINGLE STAGE BUT IT HAS AC AND HEATER CONTROLS AND IS A HUNTER ALSO. THIS THERMOSTAT HAS ALL SORTS OF BUTTONS, I CAN'T EVEN SET THE CLOCK. TO PROGRAM IT WE HAVE TO CHANGE THE TEMP EVERY TIME IT KICKS ON TO THE RIGHT SETTING. ANY HELP WOULD BE APPRECIATED. THANK YOU.
