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
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. When the safe wait time
has elapsed, the message stops flashing and
the compressor turns on.
Message flashes until safe restart
time has elapsed.
