6.4 Brief Description of Modes and Functions
1. Temperature Parameters
◆ Indoor preset temperature (Tpreset)
◆ Indoor ambient temperature (T amb.)
2. Basic Functions
Once energized, in no case should the compressor be restarted within less than 3 minutes. In the situation that memory function is available, for the first energization, if the compressor is at stop before de-energization, the compressor will be started without a 3-minute lag; if the compressor is in operation before de-energization, the compressor will be started with a 3-minute lag; and once started, the compressor will not be stopped within 6 minutes regardless of changes in room temperature.
(1)Cooling Mode
① The condition and process of cooling
If Tamb.≥Tpreset cooling mode will act, the compressor and outdoor fan will run, and the indoor fan will run at the set speed.
If Tamb.≤Tpreset-2°C, the compressor will stop, the outdoor fan will delay 30 seconds to stop, and the indoor fan will run at the set speed.
If Tpreset-2°C<Tamb.<Tpreset , the unit will keep running in the previous mode.
When 0≤ Tpreset-Tamb.＜ 2°C, if indoor fan speed is high, it will turn to medium fan speed; if indoor fan speed is medium or low, it will keep the same;(this condition will be valid only when the compressor is operating); if indoor fan speed is super high, it will keep the same;
When Tamb.-Tpreset≥1°C, the fan speed will return to set fan speed;
In this mode, the reversal valve will not be powered on and the temperature setting range is 16~30°C.② Protection function
◆ Overcurrent protection
If total current is high, the compressor will run in limited frequency. If total current is too high , the compressor will stop, the outdoor fan will delay 30 seconds to stop, indoor unit will display E5 and out door yellow light will blink 5 times.
◆ Antifreezing protection
When the antifreezing protection is detected, the compressor will stop, the outdoor fan will stop after 30 seconds, and the indoor fan and swing motor will keep running in the original mode. When antifreezing protection is eliminated and the compressor has stopped for 3 minutes, the compressor will resume running in the original mode.(2) Dehumidifying Mode
① Working conditions and process of dehumidifying
If Tamb.>Tpreset, the unit will enter cooling and dehumidifying mode, in which case the compressor and the outdoor fan will operate and the indoor fan will run at low speed.
If Tpreset-2°C≤Tamb.≤Tpreset, the compressor remains at its original operation state.
If Tamb.< Tpreset-2°C, the compressor will stop, the outdoor fan will stop with a time lag of 30s, and the indoor fan will operate at low speed.
② Protection function
Protection is the same as that under the cooling mode.
(3) Heating Mode
① The condition and process of heating
If Tamb.≤Tpreset+2°C, heating mode will act, the compressor, outdoor fan and reversal valve will run, the indoor fan will delay 3min to stop at the latest
If Tpreset +2°C<Tamb.<Tpreset +5°C,the unit will keep running in the original mode.
If Tamb.≥Tpreset+5°C, the compressor will stop, the outdoor fan will delay 30s to stop and indoor fan will blow 60s at low speed, the fan speed cannot be shifted within blow residual heat.
◆ In this mode, the temperature setting range is 16 ~30°C.
◆ The air conditioner will adjust the running frequency of the compressor automatically according to the change of ambient temperature.
◆ When the unit is turned off in heating mode, or switched to other mode from heating mode, the four-way valve will be powered off after the compressor stops.
◆ When compressor is running (not including each malfunction and protection):
a.When outdoor ambient temperature≥20°C and indoor fan speed is low or medium, the fan speed will turn to high; if indoor fan speed is high or super high, it will keep the same.
b.When outdoor ambient temperature≤18°C, the fan speed will resume set fan speed.
c. When 18°C<outdoor ambient temperature<20°C, it will run at present fan speed (set fan speed or high fan speed); but when first exiting cold air prevention after entering heating mode, it will run in set fan speed. ② Condition and process of defrost
When duration of successive heating operation is more than 45 minutes, or accumulated heating time more than 90 minutes, and one of the following conditions is reached, the unit will enter the defrost mode after 3 minutes.
(1). T outdoor ambient ＞ 5°C, T outdoor tube≤-2°C;
(2) -2°C≤T outdoor ambient ＜ 5°C, T outdoor tube≤-6°C;
(3) -5°C≤T outdoor ambient ＜ -2°C, T outdoor tube≤-8°C;
(4)-10°C≤T outdoor ambient ＜ -5°C, T outdoor tube-T compensatory ≤ (T outdoor ambient-3°C)
(5)T outdoor ambient ＜ -10°C, T outdoor tube-T compensatory ≤ (T outdoor ambient-3°C)
(after energizing, T compensatory=0°C during the first defrosting; if it is not the first defrosting, T compensatory is confirmed by T outdoor
tube of quitting last defrosting: a. when T outdoor tube ＞ 2°C, T compensatory=0°C; b. when T outdoor tube ≤ 2°C, Tcompensatory=3°C)
At that time, the indoor fan stops and the compressor stops, and after 30 seconds the outer fan will stop, and then after 30 seconds,the four-way valve will stop. After 30 seconds, the compressor is initiated for raising the frequency to defrost frequency.When the compressor has operated under defrost mode for 7.5 minutes, or T outdoor ambient ≥ 10°C, the compressor will be converted to 46Hz operation.
After 30 seconds, the compressor will stop.
And after another 30 seconds, the four-way valve will be opened, and after 60 seconds,  the compressor and the outer fan will be started, the indoor fan will run under preset cold air prevention conditions, and H1 will be displayed at temperature display area on the display panel. Defrost frequency is 85Hz.
③ Protection
◆ Cold air prevention
The unit is started under heating mode (the compressor is ON):
① In the case of T indoor amb. <24°C: if T tube≤40°C and the indoor fan is at stop state, the indoor fan will begin to run at low speed with a time lag of 2 minutes. Within 2 minutes, if T tube>40°C, the indoor fan also will run at low speed; and after 1-minute operation at low speed, the indoor fan will be converted to operation at preset speed. Within 1-minute low speed operation or 2-minute nonoperation,if T tube>42°C, the fan will run at present speed.
② In the case of T indoor amb. ≥24°C: if T tube≤42°C, the indoor fan will run at low speed, and after one minute, the indoor fan will be converted to preset speed. Within one-minute low speed operation, if T tube>42°C, the indoor fan will be converted to preset speed.
Note: T indoor amb. indicated in ① and ② refers to, under initially heating mode, the indoor ambient temperature before the command to start the compressor is performed according to the program, or after the unit is withdrawn from defrost, the indoor ambient temperature before the defrost symbol is cleared.
◆ Total current up and frequency down protection
If the total current Itotal≤W, frequency rise will be allowed; if Itotal≥X, frequency rise will not be allowed; if Itotal≥Y, the compressor will run at reduced frequency; and if Itotal≥Z, the compressor will stop and the outdoor fan will stop with a time lag of 30s.
