Operation Details
(1) The function of main control
1. Time Delay safety Control
• 3min... The compressor is ceased for 3minutes to balance the pressure in the refrigeration cycle.
(Protection of compressor)
• 30sec
...
The 4-way valve is ceased for 30sec. to prevent the refrigerant-gas abnormal noise when the Heating
operation is OFF or switched to the other operation mode while compress is off.
While compressor is running, it takes 3~5 seconds to switch.
2. Soft-Dry Operation
• The indoor fan speed is automatically set to the low, so the shift of the indoor fan speed is impossible because of
already being set to the best speed for Dry Operation by Micom Control.

troller and the operation diagram is as following
