Central Control Connection at the
Indoor Units (Fn19)
Central Control Connection function allows the field connection of
the LG AC EZ central controller to the indoor unit communications
bus on Multi V 5 systems.
For use on both heat pump and heat recovery systems.
AC EZ controller was discontinued in the U.S. market January 2016.

Power Consumption Display (Fn21)
The function tells the outdoor unit (master outdoor unit if a multi-
frame system) that power consumption should be monitored. The
function also communicates to the outdoor unit if it will be respon-
sible for reporting the data to the central control device(s), or if an
(optional) LG Power Distribution Integrator (PDI) will be responsible
for reporting.
When the optional PDI is installed, the PDI will monitor outdoor unit
power consumption. PDI allocates outdoor unit power consumed to
indoor units based on the volume of refrigerant flow through each
indoor unit during the billing period.
Power consumption data can then be viewed using an LG ACP or
AC Smart central controller, LG MultiSite Communications Manager,
and LG zone controllers. For installations where a third-party BMS
system is present, consumption data is also made available for
through LG's BACnet Gateway.
For use on both heat pump and heat recovery systems.
