Built-in compressor protection
About your new thermostat
Message flashes until safe restart
time has elapsed.
This feature helps prevent damage to the
compressor in your air conditioning or heat
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.
