intervals of 3 minutes automatically.
In heating mode, fan operation mode is not operated during the compressor in ON.
7. Hot-Start Control (Heating)
• The indoor fan stops until the evaporator piping temperate will be reached 26°C (BY TEMPERATURE).
• The indoor fan operates when 4 mins passed, even if the evaporator piping temperature is not reached 26°C.
(BY TIME).
• The operation diagram is as following.

8. Deicer Control
• Deicing operation is controlled by timer and sensing the outdoor piping temperature in heating operation mode.
• The first deicing starts when 60 minutes or more passed after starting of heating operation and the outdoor
piping temperature is -6°C or lower. 
• Deicing ends after 12 minutes or when the outdoor piping temperature is 12 or higher.
• Heating operation is repeated automatically 60 min. Heating and 12min. Deicing after the first deicing ends.
• The operation diagram is as following.
• In deicing operation, only solenoid valve of the indoor unit operated at that time is ON.
9. Forced operation
• If you lose wireless remote controller, you can operate the unit with forced operation switch.
• When you operate the unit with forced operation switch, the unit isn't always operated in operation mode which
you desire. So you can operate in uour operation mode by only remote controller.
• The standard conditions are as following :

fan speed setting.
• When room temperature reach "Stopping temperature of compressor operation", the fan and the compressor
will be stop. After 5mins passed, only fan start to operate in low mode for 2 min.
• When room temperature is between "Restarting temperature of kcompressor operation" amd "Stopping
temperature of compressor operation", operate micom dehumidify mode for 10 mins and fan operate low
speed.
• Fan will be stop after 10mins passed to operate imcom dehumidify or below or "Stopping temperature of com-
pressor operation" after 4 mins.
• When 5 mins passed after stopping compressor, fna start to low mode and 7 mins passed after stopping,
compressor start to operate micom dehumidify again. (When micom dehumidify operate, fan will operate at
