Built-In Compressor Protection - Honeywell PRO TH3000 Series Owner's Manual

Operating Manual

time has elapsed.
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 (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.
