2.Basic Functions
Once the unit energized,the compressor shall never be restarted except 3mins interval at least.For the rst energization,if the unit is at off
status before power failure, the compressor can be restarted without 3-min delay. But if the unit is at ON status before power failure, the
compressor shall be restarted with 3mins delay. Once the compressor is started up, the compressor won’t stop running within 6mins with
the change of room temperature.
(1)Cooling Mode
1. Under this mode, fan and swing function will be operating under setting mode, and temperature setting range is 61~86°F.
2. When outdoor unit is with malfunction or stop operation because of malfunction, indoor unit will keep its original operation status and
display the malfunction.
3. When 0°F≤(setting temperature-ambient temperature)<3.6°F, if indoor fan speed is at high level, it will turn to medium level (when
compressor is operating); if indoor fan speed is at ultra high level, it will not turn to other fan speed; when (ambient temperature-setting
temperature)≥1.8°F, the fan speed will resume to setting value.
(2) Dry Mode
1. Under this mode, fan will operate as low fan speed and swing at setting status, temperature setting range is 61~86°F.
2. When outdoor unit is with malfunction or stop operation because of malfunction, indoor unit will keep its original operation status and dis-
play the malfunction.
(3) Heating Mode
1. Heating Conditions and Process
When the unit is powered on and is under heating mode, IDU will turn to anti cold wind function; when the unit is powered off and the in-
door fan had ever turned on, the unit will turn to blowing residual heat.
2. When the compressor is running (doesn’t include entering each malfunction and protection):
a. When Toutdoor amblent≥68°F, if the indoor fan speed is low or medium, the fan speed will switch to high speed;if the fan speed is high
or turbo, the fan speed will not change.
b. When Toutdoor amblent≤64°F, the fan speed will turn back to set fan speed;
c. When 64°F<Toutdoor ambient<68°F, the unit will run in present fan speed (set fan speed or high fan speed); but if the unit quits anti cold
wind for the rst time in heating mode, the unit will run in set fan speed.
3.Defrosting
When there’s too much frost on outdoor condenser, the complete unit will enter into defrosting automatically to assure the best heating ef-
fect. During defrosting process, the heating indicator is on for 10s and off for 0.5s.
4.Blow Residual Heat
When heating temperature reaches to the temperature point of stop operation, compressor and outdoor fan will stop operation. The hori-
zontal louver rotates to the defaulted position in cooling mode. Indoor fan will stop operation after operating at set fan speed for 60s.
When the unit operates in heating or auto heating mode, compressor is started up and the unit will stop operation after indoor fan starts
operation. Compressor and outdoor fan stop operation. The horizontal louver will rotate to the position of breeze (defaulted position in cool-
ing). The unit will stop operation after indoor fan operates at low fan speed for 10s.
If the indoor fan stops due to blocking of PG motor, the louvers stop at the position when the unit stops. (If the unit stops for other
malfunction,the vertical louvers turn to cooling position 2) Indoor fan runs in set fan speed for 60s and then stops.
5.Cold Air Prevention
After the compressor starts, the indoor unit and louvers run in the mode below:
When Tindoor ambient<75°F: if Ttube≤104°F, the indoor fan doesn’t run and then the indoor fan runs in low fan speed after 2min. In
2min, if Ttube>104°F, the indoor fan will also run in low fan speed; after running in low speed for 1min, the indoor fan will turn to run in set
fan speed. In 1 minute of low fan speed or in 2 minute that the indoor fan doesn’t run, if Ttube>108°F, the indoor fan will turn to run in set
fan speed.
When Tindoor ambient≥75°F: if Ttube≤108°F, the indoor fan runs in low fan speed and then the indoor fan runs in set fan speed after
1min. In 1min of running in low fan speed, if Ttube>108°F, the indoor fan will turn to run in set fan speed.
Note: Tindoor ambient in
and
means at the beginning of heating mode, the indoor ambient temperature before starting up the com-
pressor, or after quitting defrosting, the indoor ambient temperature before clearing the defrosting symbol.
(4) Fan Mode
In fan mode, indoor fan operates at set fan speed, while compressor and outdoor fan all stop operation.
In fan mode, the temperature setting range is 61~86°F. Display is displaying operation icon and set temperature.
(5) Auto Mode
In auto mode, the system will select the operation mode (cooling, hearing of fan mode) according to the change of ambient temperature
automatically. The display displays operation icon, actual operation mode and set temperature. 30s will be delayed for protection during
