driven bus voltage
voltage after rectification is: 220V X 1.414=311V. It’s
normal if actual voltage varies 15v from the calculated
voltage.

compressor 2
℃
(°F)
When ambient temp is lower than 35
℃
(95°F), IPM temp
is below 80
℃
(176°F). Highest temp won’t be above
95

Inverter
compressor 2
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.

(°F)
 According to different ambient temp, for a same IDU
under cooling mode, inlet tube temp will be 1~7
℃
(33.8~44.6°F) lower than outlet tube temp.
 For a same IDU under heating mode, inlet tube temp
will be 10~20
℃
(50~68°F) lower than outlet tube temp.

Communication
parameter
Communication data
—
Quantity of IDU and ODU detected by 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.
