Operating Manual
14
Your thermostat has a feature that helps prevent damage to the compressor of your air
conditioning or heat pump system. Because damage can occur if the compressor is
restarted too soon after shutdown, this feature forces the compressor to wait 5 minutes
before restarting. During the wait time, the message Cool On or Heat On flashes on the
screen. When the safe wait time has elapsed, the message stops flashing and the
compressor turns on.
