12_ SLEEP MODE
In sleep mode, the air conditioner will first attain the desired target temperature. Then, it will allow the temperature to rise
2 °F (1 °C) higher than the target temperature for every hour for up to two hours (4 °F – 2 °C). The unit will automatically
stop working after another 6 hours of continuous running. This means the air conditioner will run less often, therefore will
be quieter.
