System
parameters
Operating freq. of
inverter compressor 1
Hz Varies from 20Hz to 95Hz
11
Current of inverter
compressor 1
A
According to different operating freq. and different
load, current will vary from 7A to 40A.
12
IPM temp of inverter
compressor 1
ºC(°F)
When ambient temp is lower than 35ºC(95°F), IPM
temp is below 85ºC(185°F). Highest temp won’t be
above 95ºC(203°F).
13
Inverter compressor 1
driven bus voltage
V
Normal bus voltage is 1.414 times of power voltage.
For example, if 3-phase power voltage is 220V, then
the bus voltage after rectification is: 220V X
1.414=311V. It’s normal if actual voltage varies 15v
from the calculated voltage.
14
Operating freq. of
inverter compressor 2
Hz Varies from 30Hz to 100Hz
15
Current of inverter
compressor 2
A
According to different operating freq. and different
load, current will vary from 7A to 25A.
16
IPM temp of inverter
compressor 2
ºC(°F)
When ambient temp is lower than 35ºC(95°F), IPM
temp is below 80ºC(176°F). Highest temp won’t be
above 95ºC(203°F).
17
Inverter compressor 2
driven bus voltage
V
Normal bus voltage is 1.414 times of power voltage.
For e xample, if 3-phase power voltage is 220V , then
the bus voltage after rectification is: 220V X
1.414=311V. It’s normal if actual voltage varies 15v
from the calculated voltage.

ODU
Operating freq of fan
motor 1
Hz Adjusts in 0~65Hz according to system pressure.
19 Current of fan motor 1 A
20
Operating freq of fan
motor 2
Hz Adjusts in 0~65Hz according to system pressure.
21 Current of fan m otor 2 A

23
Inlet tube temp of
indoor heat exchanger
ºC(°F)
● According to different ambient temp, for a same
IDU under cooling mode, inlet tube temp will be
1~7ºC(33.8~44.6°F) lower than outlet tube temp.
● For a same IDU under heating mode, inlet tube
temp will be 10~20ºC(50~68°F) lower than outlet
tube temp.

Outlet tube temp of
indoor heat exchanger
ºC(°F)
25
Opening angle of
indoor EXV
PLS
Adjusts opening angle automatically in 200~2000PLS
or 70~480PLS.

parameter
Communication data
—
Quantity of IDU and ODU dete cted b y software is the
same with actual quantity. No communication error.
27
Drainage
system
—— —
IDU can drain water out completely and smoothly.
Condensate pipe has no backward slope of water.
Water of ODU can be drained completely through
drainage pipe. No water drop from unit base.
28 Others
