Controller Options
Vertical Air Handling indoor units include LG-supplied wired controller (PQRCV-
CL0QW), but other optional LG-supplied wired controllers are available. 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 displays on the LED for about three (3) seconds when the power is first cycled on.
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, and at least FT-6
rated if local electric and building codes require plenum cable usage). Communication cable from indoor unit to remote controller(s)
is to be 22 AWG, 3-conductor, twisted, stranded, unshielded. Wiring must comply with all applicable local and national codes.
