Installation
Notes:
The ammeter device is an optional device. Without this device, the central AC system is also able to
work normally.
If users want to realize the network fee calculating function, this device is necessary. And each
outdoor unit
should equip one ammeter. Do remember to fix the power line terminals and the signal line terminals before
use.
