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 for 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
