The screen will wake up by pressing any of the five buttons. If powered by the C wire, the screen stays lit for 45 seconds after you complete changes. If powered by battery only, the screen stays lit for 8 seconds. Depending on how your thermostat was installed, the screen light may always be on.

Set the time and date
Time
Date
You can program four time periods each day, with different settings for weekdays and weekends. We recommend the pre-sets (shown in the table below), since they can reduce your heating/cooling expenses.
Wake – Set to the time you wake up and the temperature you want during the morning, until you leave for the day.
Away – Set to the time you leave home and the temperature you want while you are away (usually an energy-saving level).
Home – Set to the time you return home and the temperature you want during the evening, until bedtime.
Sleep – Set to the time you go to bed and the temperature you want overnight (usually an energy-saving level).
NOTE: To temporarily or permanently override any of the above program schedules, see page 4.

Adaptive Intelligent Recovery
Over time, the T6 Pro Thermostat “learns” how long it takes your system to reach the temperature you want. It turns on the heating or cooling system earlier to make sure you’re comfortable at the time you expect.
Built-in compressor protection
Damage can occur if the compressor is restarted too soon after shutdown. This feature forces the compressor to wait for a few minutes before restarting. During the wait time, the display will flash the message Cool On (or Heat On if you have a heat pump). When the safe wait time has elapsed, the message stops flashing and the compressor turns on.
Batteries are optional (to provide backup power) if your thermostat was wired to run on AC power when installed. If your thermostat was not wired to run on AC power, then batteries are required Install fresh batteries immediately when the low battery icon appears. The icon appears about two months before the batteries are depleted. Even if the low battery icon does not appear, you should replace batteries once a year, or before leaving home for more than a month. If batteries are inserted within two minutes, the time and day will not have to be reset. All other settings are permanently stored in memory, and do not require battery power.
NOTE: When replacing batteries, alkaline batteries are recommended.
Alerts
If there is an alert or reminder, the alert icon appears on the Home screen.
