1.2 Feature
•Inside Parts Upgrading to Increase Energy Efciency
Full DC fan motor,
Zigzag design, reduce airflow
disturbance, less vibration, less
pressure loss
Super big diameter of 550mm, enhance
heat exchange efficiency(Full series)
Particular structure for
increased wind -
cooled PCB effect.
(Full series)
Change the exchanger pipe diameter
from Φ8 to Φ7 with 0.1mm high
efficiency corrugated fins, increasing
the heat exchanger area and improving
exchanger efficiency by 30%(Full
series)
Larger capacity full DC inverter
compressor
Double rotor compressor,
adopts keel motor technology,
efficiency increased by 10%
compared to the normal type
(full series)
Tube in tube type two stage
sub-cooling design, enhance
efficiency. (double fan 4/5/6HP)
PID control to realize more
precise control of
opening degree of EEV,
compressor rotation speed,
fan speed (Double fan )
•Double pressure sensor with PID control
Implement advanced high/low voltage control
technology of compressor, which could adjust target
evaporation/ condensation temperature properly to
increase compressor frequency, ensuring the ambient
temperature reaching the setting temperature as
soon as possible.
•Intelligent defrosting technology
Intelligently judge the frosting degree by the change of low pressure and defrost temperature sensor, the ODU will
enter defrosting program only after the change reaching a specic value to extend the heating time and improve
user experience.

•Inverse balancing technology
----indoor & outdoor unit self-cleaning
Switch indoor unit and outdoor unit self cleaning module with non-
stopping, the outdoor unit waste heat can be used for heating,
defrosting and sterilizing the indoor unit.
•Quick setting and cleaning technology
Control refrigerant ow and circulating air ow.

【 Dial Switch Introduction 】
·Please check the power firstly before test , and make
sure the crankcase heater powering on for 12 hours
at least to protecting compressor.
·The switch BM1-1 is used for locking the indoor units
number, the initial status is “ OFF”. After power on,
the display board will display 【U**】, “**” indicates
the number of Indoor units that the outdoor unit can
communicate with. If it can match the actual number
of indoor units, please change “OFF” to “ON”, or else
fix the communication problem firstly.
·Forbid connecting the power wire to the “P” and “Q”,
otherwise the control board will be damaged.
·Please make sure the earth wire connecting the grou-
nding hole on the electric box firmly.
<WARNING>
Please power off firstly for about 10
minutes before checking control box,
and make sure the voltage between
P and N below 20V.

(2) Calculation method of heating capacity
----heating capacity to be known = heating capacity*(A*B*C*D*E*F) W
A. Capacity compensation value of indoor
air dry-bulb temperature condition
C. Capacity modication value under airow
variation rate of indoor unit group (only for
duct unit)
B. Capacity compensation value of outdoor air
wet-bulb temperature condition
D. Capacity compensation suitable for
total capability of indoor unit group

Notes for E:
(1) The main pipe (from outdoor to the rst branch pipe) diameter should be enlarged one size
when the single way pipe length is over 90m.
(2) When in cooling mode, outdoor is lower than indoor; or when in heating mode, outdoor is higher than indoor, the
compensation factor should be decreased the below value from gure E.
