Built-in compressor protection
This feature helps prevent damage to the
compressor in your air conditioning or heat
pump system.
Damage can occur if the compressor is
re-started too soon after shutdown. This
feature forces the compressor to wait a few
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.
Message flashes until safe restart
time has elapsed.
