Initial start up of Automatic Operation means the following either condition:
Unit start up in Automatic Operation
Automatic Operation mode is pressed while the unit is running in manual mode
Start up room temperature
COOL / HEAT
>= Remote controller setting temperature
Unit runs in COOLING mode
< Remote controller setting temperature
Unit runs in HEATING mode
