Program Schedule  
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.  
Heat  
Cool  
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).

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.  
Message flashes until safe  
restart time has elapsed.  
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.
