The High Efficiency Function (Auto Dust Throw) is set. PCB does not
need reset.
High Efficiency Function Operation
(Auto Dust Throw Mode) (Fn11)
High Efficiency Function (Auto Dust Throw Mode) helps remove
dirt / sand / debris that could have collected on the outdoor unit coil
surface. After the cooling, heating, etc., mode is satisfied and the
compressors are idle, this function will start the fan motors, operat-
ing them at full speed and in the reverse direction for a certain pe-
riod. Air is drawn in through the top of the outdoor unit, and passes
through the coil to help dislodge any loose debris.
The Auto Dust Option oP3 allows the Auto Dust Throw Mode to be
called through a third-party signal at any time. When the oP3 setting
is used, an LG I / O Module (sold separately) MUST be installed.
When the signal is sent to the outdoor unit via a third party source
(oP3), normal system operation can be interrupted, and the Auto
Dust Throw function can be performed. All other settings will not
interrupt the Multi V system operation.
Use on both heat pump and heat recovery systems.

OTHER CONTROLS
Setting Optional Modes
The Auto Dust Mode function is not a substitute for coil cleaning and does not clear the coil of all debris. A coil cleaning procedure must be included
when performing regular preventative maintenance.
