The Settings of Outdoor Unit and System
Controller Lite
In order to understand the appropriate power consumption with the System Controller Lite, it is important to
correctly transmit the electricity value measured with the power meter.
In order to do this it is necessary to configure appropriate settings on the power meter, outdoor unit, and
System Controller Lite.
The following describes the method of setting the pulse value on the controller.
Setting example
If the electricity meter you are using has units of pulses specified.

Comment
If the product has fixed settings,
configure by following the prod-
-
uct manual (pulse unit value,
VT/CT ratio, output factor, etc.).
In order to distinguish between
power meters, configure a fixed

Set it fixed at "1".
When one pulse comes from

the electricity meter, the out-
door unit will communicate "1"
to the System Controller Lite.
