12. Alarm mode display / only displayed while operating.
CO : The sensor for sensing room temperature is open or short.
C1 : The sensor for sensing piping temperature is open or short.
13.Energy Saving
➀If setting temperature of starting energy saving operation is under 22°C(71.6°F), first, setting temperature it up to 22°C(71.6°F) and perform energy saving operation.
➁After energy saving operation starts, if adaptation time of the human body pass from the point which room temperature and setting temperature meet together, increase setting temperature 1°C(1.8°F) more.
➂If it doesn't satisfy number ➀ even in 50 minutes from the start of energy saving operation, increase 1°C(1.8°F).
➃After increasing setting temperature 1°C(1.8°F) more by number ➀, ➁, perform number ➁, ➂ again, if setting temperature goes up to 25°C(77.0°F), maintain this temperature.
➄If setting temperature goes down to under 25°C(77.0°F), during the operation, do number ➁, ➂, ➃ again.

14. AUTO RESTART
In case the power comes on again after a power failure, Auto Restarting Operation is the function to operate procedures automatically to the previous operating conditions.
15. Function of changing set temperature when
Operation is set the following condition when
1.Operation mode.
Cooling/soft dry mode 
Cooling mode Heating mode 
Heating mode
2.Setting the set temperature when cooling operation.
Room temperature > Set temperature: to be set to the previous set temperature. Room temperature ≤ Set temperature
a)Room temperature ≥ 26°C(78.8°F): to be set to 24°C(75.2°F)
b)22°C(71.6°F) ≤ Room temperature ≤ 25°C(77.0°F): to be set to 21°C(69.8°F)
c)19°C(66.2°F) ≤ Room temperature ≤ 21°C(69.8°F): to be set to
d)Room temperature ≤ 18°C(64.4°F): to be set to 18°C(64.4°F)
