Built-in compressor protection
If the compressor is restarted too soon after
a shutdown, system damage can occur. The
built-in compressor protection feature forces
the compressor to wait a few minutes before
restarting, helping to prevent damage to the
heating or cooling system.
During the brief wait period, the thermostat will
flash Cool On (or Heat On if you have a heat
pump) until the wait period is over, at which point
the compressor will turn back on.
Note: The flashing Cool On or Heat On message
is also used for startup delay protection if AC
power loss occurs.
Setting the fan
Touch Fan on the thermostat home screen to
cycle through available fan modes until the
desired mode is displayed. Your changes will
save automatically.
Available fan modes:
• On: The fan will run continuously.
• Auto: The fan will run only when the heating
or cooling system is on.
• Circ: The fan will run at random intervals at
least 35% of the time to keep air circulating
throughout your home.
