Understanding Temperature Recovery Feature

Your thermostat comes with a feature called Adaptive Intelligent Recovery™,

which eliminates all guesswork when setting your schedule. How long does it

take the furnace to warm your house in the morning before you get out of bed

or how long does it take the air conditioner to cool your house in the afternoon

before you return from work? No problem. The thermostat determines that for

you.

Simply set your program schedule to the time you want the house to be at your

comfort temperature. The thermostat then turns on the heating or cooling at

just the right time to have your home reach your scheduled temperature at

your scheduled time.

For example—you get out of bed at 6:00 AM and want the temper-ature to be

70°F. Set the Wake period for 6:00 AM and 70°F. The thermostat then turns on

the heat before 6:00 AM to raise the temperature to 70°F by 6:00 AM.

The thermostat alerts that the heating or cooling system is coming on before a

scheduled time when “Recovery” shows on the screen.

It takes about a week for the thermostat to adjust to local

weather, your schedule, the construction of your home and

your heating and/or cooling system. Each day it adjusts the

next day’s recovery start time accordingly.
