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
If 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.
After 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.
If it doesn't satisfy number
1°C(1.8°F).
After increasing setting temperature 1°C(1.8°F) more by number
temperature goes up to 25°C(77.0°F), maintain this temperature.
If setting temperature goes down to under 25°C(77.0°F), during the operation, do number

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.
