Why is my RTH8500WF WiFi Series WiFi Touchscreen Programmable Thermostat not following my schedule?
Your thermostat is equipped with the Adaptive Recovery feature, which allows the thermostat to ""learn" how long it takes to reach a desired setpoint and begin heating or cooling earlier than your scheduled start time. To disable this feature, go to use the User Guide to access the Installer Setup.
Other causes can include incorrect time setting on the thermostat, or if connected to WiFi and registered, incorrect zip code being listed under the location settings. *Only available to modify from the My Total Connect Comfort web portal – not currently supported in the mobile app*
