Message flashes until safe restart 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 feature 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.
