Controller Options
Ceiling-concealed duct (low static) indoor units include an LG-supplied wired controller
(AKB72955816) , but other optional LG-supplied wired controllers are available (see
1
Controls and Options overview on pages 9 to 12 in this manual's Introduction section).
The wireless handheld controller (Model No. PQWRHQ0FDB) is also an optional
accessory with use of the wired controller.
• Operation Display Panel: Displays operation conditions.
• Temperature Control Button: Sets desired temperature.
• Fan Speed Button: Sets desired fan speed.
• On / Off Button: Turns system operation on and off.
• Mode Selection Check Button: Selects the operation mode: Cooling, Heating, Auto,
Dry (Dehumidification), or Fan.
Each function will display on the LED for about three (3) seconds when the power is first cycled on.
Simple Mode Controllers for the ceiling-concealed duct (low static) indoor units are also referenced by Model No. PQRCVCL0QW.

Wired Controller Connections
Controllers can connect to the indoor unit in one of two different
ways.
1. LG Wired Remote Extension Cable with Molex plug (PZCWRC1;
sold separately) that connects to the CN-REMO terminal on the
indoor unit PCB.
2. Field-supplied controller cable that connects to the indoor unit
terminal block (must be at least UL2547 or UL1007, 22 AWG,
two-core, one-shield core, at least FT-6 rated if local electric and
building codes require plenum cable usage).
When using field-supplied controller cable, make sure to connect
the yellow to yellow (communications wire), red to red (12V power
wire), and black to black (ground wire) terminals from the remote
controller to the indoor unit terminal blocks.
