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.
