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

•
Ƹ
T

) •
T
setup
] ≤ 0.5ć, start the machine to enter into heating operations for heating;
(2) During operations of heating, if 0ć ≤ [(T

•
Ƹ
T

) •
T
setup
] < 2ć, the heating operation will be still running;
(3) During operations of heating, if 2ć ≤ [(T

) •
T
setup
], the heating operation will stop after reaching the temperature point.
2. The temperature setting range in this mode is: 16~30ć.
3. Special Functions
(1) Defrosting Control
1. Conditions for starting defrosting
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.
(1) Time conditions for judging to start defrosting:
Item
Enter into defrosting control first time
Enter into defrosting definition first time
Start the machine and enter into heating mode and run
defrosting, the defrosting operation will start; if the events
below happen, reset the first defrosting:
(1) After the compressor stops for 2 hours;
(2) Switching to the cooling/dehumidifying mode;
Enter into defrosting control
next time
Time for
entering into
defrosting
If the time of compressor continuously running ≥ [t
time of
entering into defrosting the first time
] or the time of compressor
continuously running < [t
time of entering into defrosting the first time
],
and the time of the compressor continuously running for
totally 50 minutes (Note: The time is calculated when the
outer pipe temperature T
outer pipe
≤ 3ć)
Determine the judgment
start time of defrosting of
this time according to the
judgment time of defrosting
of the last time and the
defrosting time
T ≤ 150s The time of judging to enter into defrosting extends 10 minutes
150s < T ≤ 180s The time of judging to enter into defrosting extends 5 minutes
180s < T ≤ 240s The time of judging to enter into defrosting is unchanged
240s < T ≤ 300s The time of judging to enter into defrosting is shortened for 2 minutes
300s < T ≤ 360s The time of judging to enter into defrosting is shortened for 4 minutes
Defrosting
time
360s < T The time of judging to enter into defrosting is shortened for 6 minutes
The maximum defrosting time interval [t
max. defrosting time interval
] is 60 minutes, the minimum defrosting time
interval [t
min. defrosting time interval
] is 30 minutes.
