Built-in compressor protection
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 fea-
ture 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 model). When the safe wait time
has elapsed, the message stops flashing and
the compressor turns on.
Message flashes until
safe restart time has
elapsed.
