3.2 Outdoor frequency control 3.2.1 Compressor running frequency range: 20~90RPS 3.2.2 Defination of high-efficiency operation and its frequency control In order to meet the cooling request at high ambient temperature and the heating request at low ambient temperature, we set the high-efficiency operation. Entering condition: cooling mode, Tao≥33(E), heating mode, Tao≤5(E). 3.3 Electronic expansion valve (EEV) control 3.3.1 Electronic characteristic

3.3.4 Standard open angle control In Cool/Dry mode, standard open angle: outdoor ambient temp.≥20, 250 pulse(E);

Outdoor ambient temp.＜20, 210 pulse(E); In Heat mode, standard open angle: outdoor ambient temp.≥10, pulse (E);

outdoor ambient temp.＜10, 210 pulse (E). 3.3.5 When discharging temp. Td is too high, modify the EEV angle. In order to cooperate the compressor discharging temp. over high protection, the system will enlarge the EEV open angle. Within 5 minutes after compressor starts up, it will not modify. The detecting period is 30 seconds.

<=90 -5degree/30seconds, and reduce to 0 degree gradually 3.4 4-way valve control in heating Protection when 4-way valve can not reverse in heating: 10 minutes later after compressor startup, if indoor coil average temp. is below 15degree and keeps for 1 minute, the unit will stop and occur the 4-way valve protection. compressor ON OFF 4-way valve ON OFF 15s（E） 2minutes and 55s 3.5 Electric heater control If compressor has not run for a long time, the refrigerant will deposit on the bottom of compressor and mix with the refrigeranr oil. When re-startup, because low pressure reduces, refrigerant will be segregated from the refrigerant oil and cause soam in the oil, which will make compressor exhaust a lot of oil. Therefore please stop heating the compressor bottom to ensure the low pressure in startup period should not go down greatly. Ambient temp. TA≤27degree, when compressor stops, the electric heater will be electrified. When TA≥32degree, or compressor running, the electric heater will be off.

Heater ON OFF Ambient temp. TA() 27 32 3.6 Control of liquid spray valve SV2: According to the compressor discharging temp., open or close the SV2. ①Control condition: A. In every mode (including defrosting and oil return operation), the control can work. B. In 3 minutes after compressor startup, ignore the abnormal compressor suction and discharging value. ②3 minutes later after compressor startup, according to the discharging temp., the following procedure

will be taken: Td≤90, SV2 close; Td＞110, SV2 open. ③In 150 seconds when compressor stops, in order to keep the system in balanc, please open the liquid

spray valve SV2. 150 seconds later after compressor stops, SV2 close. 3.7 Control of defrosting in heating In heating mode, defrosting temp. sensor will check the frosting condition of outdoor heat exchanger and make defrosting control. 3.7.1 Enter condition: ①In heating mode, if the compressor has run for 10 minutes continously and run for 45 minutes in all, the

system will measure the defrosting temperature sensor Te and outdoor ambient temp. sensor TA, if the below condition can be met for continous 5 minutes, the unit will enter defrosting operation:

Checking Pause: thermostat OFF, or the unit stops. 3.7.2 Cancel condition: It will take the max. 10 minutes from beginning defrosting to quit it. Te sensor will measure the condition of outdoor heat exchanger, if the temp. is over 7 for 60 seconds in all or is up to 12 for 30 seconds in all, the defrosting will be over. 3.7.3 Compulsory defrosting control Enter condition: in heating mode, after receiving the compulsory defrosting signal from indoor unit, the unit will perform the compulsory defrosting operation. Cancel condition: Te≥12 and keep for 1 minute or the defrosting time is over 10 minutes. The manual defrosting signal of indoor unit will remain until the outdoor enters defrosting mode. Note: When outdoor compressor not running, the unti still can enter manual defrosting, but it will comply with the 3-minute protection of compressor.

3.10 High pressure protection When the input signal of pressure switch is high level:1, that shows there is no protection. When the input signal of pressure switch is low level: 0 for 1 minute, that shows high pressure protection works. At this time, compressor stops, outdoor will send the alarm signal. The alarm can be resumable. If in 60 minutes, the failure occurs 3 times, the failure can be confirmed and send failure code to indoor. Meanwhile, by controling the max. condensate temp. Tc (cooling) or TmAVE (heating), please confirm as follow: In nominal cooling/dry/heating mode, high pressure can be controlled by limiting the max. frequency. 3.11 Low pressure protection (1) When compressor is running, if output signal of low pressure switch is low level: 0 for 1 minute

continously, compressor will stop,outdoor alarms. The alarm can be resumable. If in 60 minutes, the failure occurs 3 times, the failure can be confirmed and send failure code to indoor.

(2) When compressor no running, if output signal of low pressure switch is low level: 0 for 30 seconds continously, alarm will occur.

·When unit stops, the reason that system still checks the low pressure : in a long time stop, make protection for the compressor on the condition of great refrigerant leakage.

·The reason that low pressure switch action time is 30 seconds: when compressor stops, low pressure does not change, so it will be shorter than the set time in operation. (3) When compressor starts up, in 8 minutes, low pressure switch signal will be shielded. (4) In defrosting, low pressure switch will be shielded. (5) In oil return procedure, low pressure switch will be shielded. (6) In the refrigerant discharging procedure after the oil return in cooling is over, low pressure switch will be shielded. In addition, the system will control low pressure through the evaporator temp. TE to realize the low pressure protection function.

The incorrect dip switch setting will result in the system wrong operation or the wrong failure diagnosis. 2. Cooling operation 2.1 The set temperature in cooling: TS=the set temp. on remote controller 2.2 After cooling startup, indoor unit will send the frequency code to outdoor according to the temp. difference between the set temp. and the ambient temp. 3. Heating operation 3.1 In heating operation, the set temp. TS=the set temp. on remote controller 3.2 After heating startup, indoor unit will send the frequency code to outdoor according to the temp. difference between the set temp. and the ambient temp. 4. Dry operation Room temp.-(set temp.+ tolerance) ＞2, indoor operation is identical to the cooling operation, and sends the cooling operation signal to outdoor. Room temp.-(set temp.+ tolerance) ≤2, indoor unit sends the dry operation signal to outdoor. Room temp. ＜16, indoor unit stops running and sends stop-unit signal to outdoor. 5. Fan operation Indoor fan motor will run as the fan speed set on the remote controller and indoor unit will send the stop-unit signal to outdoor. 6. Auto operation If the unit enters Auto mode for the first time, the system will adjust the operation mode according to the room temp. and the set temp. When room temp.≥set temp., entering cooling mode; When room temp.＜set temp., entering heating mode. Mode conversion will be confirmed after compressor has stopped for 15 minutes. 7. Abnormal operation When outdoor modes from the request of indoor unit conflict, the one entering firstly will take priority. After indoor receives the ON command from remote controller, it will firstly confirm the outdoor current operation mode. If they are the same mode, indoor unit will run as the request of remote controller. If they are different modes, the system will forbid to operate, and indoor will keep the OFF mode. After setting on remote controller, if the buzzer sounds two times, that shows abnormal operation. Indoor will run until the outdoor mode and the requested mode of remote controller are the same. 8. Compensation control for discontinuous operation After the unit starts up in cooling/heating mode, in 3 minutes, the compressor run/stop will not be controlled by the room temp., but after changing the set temp., if compressor stop condition can be met, the system will stop compressor immediately. 9. Anti-cold air control In heating mode, after compressor startup, the system will control indoor fan motor according to indoor coil temperature. At the beginning of startup, the indoor fan motor can run only when indoor mid-coil temp. is over 28(±2). When indoor mid-coil temp. goes down to 18(±2), indoor fan motor will stop running.

In defrosting period, indoor fan motor will stop running; In heating mode, if unit shutoff, indoor fan motor will stop after running for 30 seconds at super low speed. Note: The above temp. point has taken fuzzy control, and has tolerance ±2 according to the different state. 10. Fan motor control in defrosting 10.1 On receiving outdoor defrosting signal, indoor unit will stop after blowing remaining heat at slow speed for 20 seconds. 10.2 In defrosting period, indoor fan motor stops running. 10.3 Defrosting is over, and indoor motor will run as anti-cold air state. 11. Blowing remaining heat operation When the unit shuts off in heating mode or the thermostat is OFF, indoor motor will stop running after running at super low speed for 30 seconds. 12. Anti-freezed protection (invalid in heating mode) When compressor has run for over 5 minutes, to prevent indoor evaporator freezing (in cooling/dry mode), if indoor mid-coil temp. is below 0 degree, compressor will stop. When indoor mid-coil temp. is over about 10 degree, the unit can run. After compressor has stopped for 3 minutes, the unit can re-start up. Note: The above temp. point has taken fuzzy control, and has tolerance ±1 according to the different state. 13. Overload protection in heating mode It is valid only in heating mode, if indoor mid-coil temp. is over about 65 degree continuously for 10 seconds, indoor will stop; while when indoor mid-coil temp. is below 52 degree, indoor will resume. Note: The above temp. point has taken fuzzy control, and has tolerance ±1 according to the different state. 14. Timer operation TIMER ON/TIMER OFF/TIMER ON/OFF. Timer will count according to the time difference between the TIMER clock and the present clock. In TIMER state, TIMER indicator will be ON. 15. SLEEP function In cooling/dry mode, after running for 1 hour, the set temp. will increase 1, another 1 hour later, the set temp. will increase 1 again, then 6 hours later, it will stop. In heating mode, after running for 1 hour, the set temp. will reduce 2, another 1 hour later, the set temp. will reduce 2 again, then 3 hours later, the set temp. will increase 1, and another 3 hours, it will stop. 16.
