This feature helps prevent damage to the com-
pressor 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.
