(1) If T
outdoor ambient
≥ [T
low-temperature cooling
], the temperature can be set at: 16~30
o
C (Cooling at room temperature);
(2) If T
outdoor ambient
< [T
low-temperature cooling
], the temperature can be set at: 25~30
o
C (Cooling at low temperature), that is, the minimum setting
temperature for outdoor unit judgment is 25
o
C.
(2) Dry Mode
1. Conditions and processes of dry operations: Same as the cooling mode;
2. The temperature setting range is: 16~30
o
C;
(3) Fan Mode
1. The compressor, outdoor fan and four-way valve are switched off;
2. The temperature setting range is: 16~30
o
C.
(4) Heating Mode
1. Conditions and processes of heating operations: (T
indoor ambient is the actual detection temperature of indoor environment thermo-bulb
, ΔT
heating indoor ambient temperature compensation
is the indoor ambient temperature compensation during heating operations
)
(1) If the compressor is stop, and [(T
indoor ambient
–ΔT
heating indoor ambient temperature compensation
) –T
preset
] ≤ 0.5
o
C, start the machine to enter into heating
operations for heating;
(2) During operations of heating, if 0
o
C ≤ [(T
indoor ambient
–ΔT
heating indoor ambient temperature compensation
) –T
preset
] < 2
o
C, the heating operation will be still
running;
(3) During operations of heating, if 2
o
C ≤ [(T
indoor ambient
–ΔT
heating indoor ambient temperature compensation
) –T
preset
], the heating operation will stop after
reaching the temperature point.
2. The temperature setting range in this mode is: 16~30
o
C.
(5) Defrosting Control
1. After the time for defrosting is judged to be satisfied, if the temperature for defrosting is satisfied after detections for continuous
3minutes, the defrosting operation will start.
2. Start to defrost: Compressor stops and starts up 55S later;
(1) T
outdoor pipe
≥ 12
o
C;
(2) T
outdoor ambient
<-5
o
C, and the T
outdoor pipe
≥ 6
o
C last more than 80S;
(3) The continuous running time of defrosting reaches to 8min.
(6) Compressor Control
1. The frequency of compressor will be controlled with the relationship of ambient temperature and preset temperature and changing
speed of ambient temperature;
2. Start the compressor after starting cooling, heating, dry operations, and the outdoor fan start for 5s;
3. When the unit is off, in safety stops and switching to fan mode, the compressor will stop immediately;
4. In all modes: once the compressor starts up, it will not be allowed to stop until having run for the [T
min. 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.);
5. 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).
(7) Outdoor Fan Control
1. When the unit is off by remote control, in safety stops and stop after reaching to the temperature point.
2. In fan mode: The outdoor fan stops;
3. Start to defrost: Outdoor fan will stop after compressor stops for 50S;
(8) 4-way valve control
2. When the unit is on in heating mode, the 4-way valve is energized;
3. When the unit is on in heating mode and heating mode shift to other modes, the 4-way valve will be de-energized after compressor
stops for 2min;
4. After protection stops, the 4-way valve will be de-energized after 4min;
5. Start to defrost: The power of 4-way valve will be de-energized after the compressor stops;
