this conditions are continuous for 5 minutes.
7. Minimum Frequency Operation Protection
∙ When the compressor operates at less than 37Hz for 60 minutes, the operating frequency will increase to 37Hz for 2
minutes.
8. Low Frequency Operation Protection
∙ When the following conditions occur, the compressor will operate at minimum 37 Hz.
Indoor intake temp.( ) 30 or 15 28 or 19
Outdoor air temp.( ) 38 or 16 24 or 4
Indoor heat exchanger temp.( ) 30 30
Operation Cooling / Soft Dry Heating
9. DC Peak Current Control
∙
When the electric current to the power transistor exceeds the set value, DC 35±4A, the compressor stops. The compressor
restarts after 3 minutes.
∙ If within 30 seconds the set value exceeds again after start of the compressor, all indoor and outdoor relays will be turned
off and all the LEDs will blink.
10. DC Reset
∙ When the voltage supply (DC) to power transistor is below the set value i.e, 178±5V, the compressor is stopped. The
compressor will restart after 3 minutes.
∙
If within 30 seconds the voltage supply (DC) is below the set value again after start of the compressor, all indoor and outdoor
relays will be turned off and all the LEDs will blink.
11. High Power Supply Voltage Protection
∙ When the voltage supply (AC) exceeds 295 ± 15V(T ), the air conditioner stops and restarts automatically when the voltage
supply (AC) is below (T -5)V. However, waiting for 3 minutes is necessary for re-operation.
