1 Q: Maintain the previous instruction cycle. R: Rise at the speed of Hz/0s If TC>=65 and continues for 5s the unit will shutdown, outdoor fault indicator lamp will blink and fault will not be reported to indoor unit. When compressor shutdown exceeds minutes, and TC<48 compressor will restart..4.overcurrent Prevention and Control During startup of compressor, if current is larger than A (The value is represented by A.) for s, compressor will shutdown and alarm, After minutes, compressor will restart. In the event restart occurs times in 0 minutes, compressor will stop and alarm to determine the fault. Compressor can only continue operation when power is cut off. Overcurrent Frequency Drop Protection When current is larger than A compressor frequency will drop at a speed ofhz/s. When current is lower than A and higher thana, frequency drop will stop and frequency will be increased at a speed of HZ/0s. When current is lower than 9A target operation frequency will be resumed..5. Indoor Heat Exchanger Anti-freeze Protection Anti-freeze during cooling When T C 5 compressor frequency will drop at a speed of HZ/0s When T C starts to rise and 6 =T C =7 compressor frequency will remain unchanged. When 7 T C, frequency will rise at a speed of HZ/0s. If TC<=0 for consecutive minutes, compressor will shutdown and outdoor fault lamp blinks. Fault will not be reported to indoor unit. When compressor shuts down for more than minutes and when TC>7 compressor will restart..6.outdoor Temperature Limit Cooling: When outdoor temperature is lower than 5, cooling operation will start, compressor frequency is limited to less than 50 HZ, outdoor wind speed is forced at level. Heating: When outdoor temperature is higher than 0, heating operation will start, compressor frequency is limited to less than 50 HZ, outdoor wind speed is forced at level..7 Rated Operation Rated Cooling: When receiving the instruction of indoor unit rated operation, the unit will start rated cooling operation. Rated Heating: When receiving the instruction of indoor unit rated operation, the unit will start rated heating operation..8: Special Features,Power Operation: When receiving indoor power signal, the unit will operate as per frequency set by EEPROM, fan rotate speed is determined by ambient temperature and frequency. Power operation will stop when indoor power signal is cancelled.,silence Operation: When receiving indoor silence signal, the unit will operate as per frequency set by EEPROM, fan rotate speed is determined by ambient temperature and frequency. Power operation will stop when indoor silence signal is cancelled. 9

2 . Forced Cooling: When receiving indoor forced cooling signal, cooling operation will start in a frequency signaled by indoor unit. Only air discharge temperature and overcurrent protection features are effective and other protection features are invalid. 4. Rated, Middle and Minimum Capacity Operation: When receiving indoor, rated, middle and minimum capacity operation signal, outdoor unit will operate as per wind speed and frequency set by EEPROM and all the protection features are effective. Three. Fault Display and Treatment In case outdoor unit faults, the alarm indicator lamp will blink and blink frequency is HZ Time interval between blink cycles is s. Alarm indicator lamp is off when there is no fault. Three are three ways of fault alarm. It is ensured that fault alarm indicator lamp will blink for more than minutes and 0s each time. : Resumable Alarm, fault code is sent to indoor unit. : Resumable Alarm if there are consecutive non-resumable fault codes in 0 minutes, it need to restart by cut off the power. 0
