About your new thermostat
Early Start: This feature allows the heating or 
cooling to turn on before the program start 
time, so the temperature is reached at the time 
you set. For example: Set the Wake time to 6 
am, and the temperature to 70°. The heat will 
come on before 6 am, so the temperature is 
70° by the time you wake at 6. The next time 
period is displayed when the system is acti-
vated before a scheduled time period.
