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;
(2) Dehumidifying Mode
Working conditions and process of dehumidifying

operate at low speed.
(1) COOL mode
The condition and process of cooling
If T
amb.≥Tpreset
COOL mode will act, the compressor and outdoor fan will run, and the indoor fan will run at the set
speed.
If T

, 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 ≤T

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 outdoor
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.

(3) HEAT Mode
①
Working conditions and process of heating
If Tamb.≤Tpreset +2°C, the unit enters heating mode, in which case the four-way valve, the compressor and the outdoor fan will
operate simultaneously, and the indoor fan will run at preset speed in the condition of preset cold air prevention.
If T amb.≥Tpreset +5°C, the compressor will stop, the outdoor fan will stop with a time lag of 30s, and the indoor fan will stop after
60-second blow at low speed
If Tpreset +2°C<T amb.< Tpreset +5°C, the unit will maintain its original operating status. Under this mode, the four-way valve is energized and temperature can be set within a range of 16 - 30°C. The operating symbol, the
heating symbol and preset temperature are revealed on the display.
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, T
compensatory=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.

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 non-
operation, 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≤6A, frequency rise will be allowed; if Itotal≥7A, frequency rise will not be allowed; if Itotal≥8A, the compressor
will run at reduced frequency; and if Itotal≥9A, the compressor will stop and the outdoor fan will stop with a time lag of 30s.
(4) Fan Mode
Under the mode, the indoor fan will run at preset speed and the compressor, the outdoor fan, the four-way valve and the electric
heater will stop.
Under the mode, temperature can be set within a range of 16 - 30°C .
(5) AUTO Mode
①
Working conditions and process of AUTO mode
a. When T ambient ≥26°C, the unit will operate in Cool mode. The set temperature is 25°C. b. When T ambient ≤22°C, the heat pump unit will operate in Heat mode., set temperature be 20°C; the cooling only unit will operate in Fan mode, set temperature be 25°C. c. When 23°C≤T ambient ≤25°C, the unit will operate in the previous state. If it is energized for the rst time, it will operate in Fan
mode.

remain unchanged for at least 6 minutes.
(6) Common Protection Functions and Fault Display under COOL, HEAT, DRY and AUTO Modes
①
Overload protection
T tube: measured temperature of outdoor heat exchanger under cooling mode; and measured temperature of indoor heat exchanger
under heating mode.
1) Cooling overload
a. If T tube≤52°C, the unit will return to its original operation state. b. If T tube≥55°C, frequency rise is not allowed. c. If T tube≥58°C, the compressor will run at reduced frequency. d. If T tube≥62°C, the compressor will stop and the indoor fan will run at preset speed.

②
Exhaust temperature protection of compressor
If exhaust temperature ≥98°C, frequency is not allowed to rise. If exhaust temperature ≥103°C, the compressor will run at reduced frequency. If exhaust temperature ≥110°C, the compressor will stop. If exhaust temperature ≤90°C and the compressor has stayed at stop for at least 3 minutes, the compressor will resume its operation.
③
Communication fault

compressor will resume its operation. If module protection occurs six times in succession, the compressor will not be started again.
⑤
Overload protection
If temperature sensed by the overload sensor is over 115°C, the compressor will stop and the outdoor fan will stop with a time lag of 30 seconds. If temperature is below 95°C, the overload protection will be relieved°C.
⑥
DC bus voltage protection
If voltage on the DC bus is below 150V or over 420V, the compressor will stop and the outdoor fan will stop with a time lag of 30
seconds. When voltage on the DC bus returns to its normal value and the compressor has stayed at stop for at least 3 minutes, the
compressor will resume its operation.
