2. Basic Functions
(1) Cooling Mode
1. Conditions and processes of cooling operation:
(1) If the compressor is shut down, and [Tsetup – (T
indoor ambient temperature
– ⊿T
cooling indoor ambient temperature compensation)
] ≤ 0.5 , start up the machine
for cooling, the cooling operation will start;
(2) During operations of cooling, if 0ºC ≤ [Tsetup – (T
indoor ambient temperature
– ⊿T
cooling indoor ambient temperature compensation)
] < 2 , the cooling operation
will be still running;
(3) During operations of cooling, if 2ºC ≤ [Tsetup – (T
indoor ambient temperature
– ⊿T
cooling indoor ambient temperature compensation)
], the cooling operation will
stop after reaching the temperature point.
2. Temperature setting range
(1) If T
outdoor ambient temperature
≥ [T
low-temperature cooling temperature
], the temperature can be set at: 16~30ºC (Cooling at room temperature);
(2) If T
outdoor ambient temperature
< [T
low-temperature cooling temperature
], the temperature can be set at: 25~30ºC (Cooling at low temperature), that is, the
minimum setting temperature for outer units judgment is 25ºC .
(2) Dehumidifying Mode
1. Conditions and processes of dehumidifying operations: Same as the cooling mode;
2. The temperature setting range is: 16~30ºC ;
(3) Air-supplying Mode
1. The compressor, outdoor fans and four-way valves are switched off;
2. The temperature setting range is: 16~30ºC.
(4) Heating Mode
1. Conditions and processes of heating operations: (Tindoor ambient temperature is the actual detection temperature of indoor environment
thermo-bulb, Theating indoor ambient temperature compensation is the indoor ambient temperature compensation during heating
operations)
(1) If the compressor is shut down, and [(T

– ⊿T
heating indoor ambient temperature compensation
) –T
setup
] ≤ 0.5 , start the machine to
enter into heating operations for heating;
(2) During operations of heating, if 0ºC ≤ [(T
indoor ambient temperature
–⊿ T
heating indoor ambient temperature compensation
) –T
setup
] < 2 , the heating operation
will be still running;
(3) During operations of heating, if 2ºC ≤ [(T
indoor ambient temperature
– ⊿T
heating indoor ambient temperature compensation
) –T
setup
], the heating operation will
stop after reaching the temperature point.
2. The temperature setting range in this mode is: 16~30ºC .

3. Special Functions
Defrosting Control
①
Conditions for starting defrosting
After the time for defrosting is judged to be satised, if the temperature for defrosting is satised after detections for continuous 3minutes,
the defrosting operation will start.
②
Conditions of nishing defrosting
The defrosting operation can exit when any of the conditions below is satised:
③
T
outdoor pipe temperature
≥ (T
outdoor ambient temperature
– [T
temperature 1 of nishing defrosting
];
④
The continuous running time of defrosting reaches [tmax. defrosting time].
4. Control Logic
(1) Compressor Control
Start the compressor after starting cooling, heating, dehumidifying operations, and the outer fans start for 5s; When the machine is
shutdown, in safety stops and when switching to air-supplying mode, the compressor will stop immediately. In all modes: once the
compressor starts up, it will not be allowed to stop until having run for the [tmin. compressor running time] (Note: including cases of
shutdown when the temperature point is reached; except the cases requiring stopping the compressor such as fault protection, remote
shutdown, mode switching etc.); In all modes: once the compressor stops, it will be allowed be restart after 3-minute delay (Note: The
indoor units have a function of power memory, the machine can be restarted after remote shutdown and powering up again without
delay).
1. Cooling mode
Start the machine to enter into cooling operation for cooling, the compressor is switched on.
2. Dehumidifying mode
Same as the cooling mode.
3. Air-supplying mode
The compressor is switched off.
4. Heating mode
(1) Start the machine to enter into heating operation for heating, the compressor is switched on.
(2) Defrosting:
a. Defrosting starts: the compressor is shut down, and restarts it after 55-second delay.
b. Defrosting ends: the compressor stops, then starts it after 55-second delay.
(2) Outer Fans Control
Notes:
Only the outer fans run for at least 80s in each air ow speed can the air ow be switched;
After the outer fans run compulsively in high speed for 80s when the machine starts up, control the air ow according to the logic.
After remote shutdown, safety stops, and when the machine stops after reaching the temperature point, as well as after the compressor
stops, extend 1 minute, the outer fans will stop (During the period in the 1 minute, the air ow of outer fans can be changed according to
the outdoor ambient temperature changes); When running with force, the outdoor fans shall run in the highest air ow.
(3) 4-way valve control
1. The 4-way valve control under the modes of Cooling, dehumidication and supplying air: closing;
2. The status of 4-way valve control under the heating mode: getting power;
(1) 4-way valve power control under heating mode
a. Starts the machine under heating mode, the 4-way valve will get power immediately.
(2) 4-way valve power turn-off control under heating mode
a. When you should turn off the power or switch to other mode under heating mode, the power of 4-way valve will be cut after 2 minutes
of the compressor stopped.
b. When all kinds of protection stops, the power of 4-way valve will be cut after delaying 4 minutes.
(3) Defrosting control under heating mode:
a. Defrosting begins: The power of 4-way valve will be cut after 50s of entering into the defrosting
compressor.
b. Defrosting stops: The 4-way valve will get power after 50s of exiting the defrosting compressor.
(4) Evaporator frozen-preventing protection function
At the mode of Cooling, dehumidifying:
Evaporator frozen-preventing protection function is allowed to begin after 6 min of starting the compressor.
