• Pd10 - Monitor the value from the watt hour meter.
• Pd11 - Monitor the calculated value in the outdoor unit. (error ± 5%)
■ Detailed information
• This function is used with heat pump and heat recovery.
• All modes is a change in the setting impact.
• When the optional PDI is installed, the PDI monitors outdoor unit power consumption as well as
indoor 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. For VRF systems
without the PDI, outdoor unit power consumption is reported, however indoor unit power consump-
tion is ignored.
• If the Smart Plug function is turned on, the power consumption data may be viewed using one of
LG's central control/monitoring devices such as ACP, AC Smart, or the multi site communications
manager. For installations where a third party BMS system Is present, consumption data is also
made available for viewing at the BMS front end using LG's BACnet gateway.
· Ask an authorized technician to setting a function.
· When PDI is installed, be sure to set the outdoor unit option to PDI ('PDI1').
(If the setting is not set to PDI1, the value displayed on the remote control may differ from the
actual value.)
· It is possible to check the power consumption during operation while setting the function, but it can
differ value compared to actual power consumption.
