About your new thermostat
Smart Response® Technology: This feature 
allows	the	thermostat	 to	“learn”	 how	long	
the furnace and air conditioner take to reach 
programmed temperature settings, 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	 message	 “In	
Recovery”	 is	displayed	 when	the	system	 is...
