This feature helps prevent
damage to the compressor in
your air conditioning or heat
pump system.
Damage can occur if the
compressor is restarted too
soon after shutdown. This
feature forces the compressor
to wait 5 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.
