A:Answer A lot of things can be happening. First, not sure how familiar your friend is with the thermostat. If you walk near it, the first thing that pops up is the actual temperature, not the setting. If it was a cooler day or evening and he walked by the thermostat, it would initially show the current temp which may have been 75. Also, are you sure you set it to ECO temp setting or just turned it down? If you just turned it down, the timer will take it to the next setting at the next time. Finally, do you have a smart phone App? You can check it, change it any time you want as long as your phone is connected and the Wi-Fi is on at your Florida place.
