WIRING
Optional Wall-Mounted Sensor and Controller
Wall-Mounted Sensor Installation
Proper indoor unit operation depends on the location of the room sensor. A good location will protect the zone controller from direct sunlight
and external local sources of water vapor, and heated or cooled air. If no mounting height was specified by the building designer, place the
handy box approximately fifty-five (55) inches above the finished floor.
• It may be necessary to use a handy box that is sized in metric units, depending on the controller model. Check with your LG representative
to verify which size of handy box is needed for the zone controller in question.
• Use only LG-supplied communications cable. Using field-supplied cable may result in communications problems between the zone control-
ler and the indoor unit.
• Maintain the minimum distance required between the communications cable and power wiring. The minimum required space between
the two is dependent on the voltage of the power wiring. Refer to the appropriate Multi V Outdoor Unit Engineering Manual for minimum
distance specifications.
Do not route power wiring and communications cables in the same conduit.
Do not cut the quick-connect plugs off or adjust the length of the cable. Keep the communications cable away from high voltage wires
and electromagnetic field (EMF) producing equipment.
Wall-Mounted Controller Installation
Since the room temperature sensor is inside the remote controller, the remote controller should be installed in a place away from direct sun-
light, high humidity and direct supply of hot or cold air to maintain proper space temperature. Install the remote controller about 5 ft above
the floor in an area with good air circulation and an average temperature.
Do not install the remote controller where it can be affected by the following:
• Drafts or dead spots behind doors and in corners
• Hot or cold air from ducts
• Radiant heat from sun or appliances
• Concealed pipes and chimneys
• Uncontrolled areas such as an outside wall behind the remote controller
This remote controller is equipped with a seven segment LED display. For proper
display of the remote controller LED's, the remote controller should be installed
properly as shown below. The standard height is 4 - 5 ft from floor level.
1. Pull communications cable between the zone controller handy box (if used) and
the indoor unit. The wall-mounted zone controller comes with a thirty (33) foot
length of cable.
2. Store a minimal amount of cable in the handy box. Any additional cable should be
coiled and stored near the indoor unit control panel.
3. If additional cable length is needed, order a thirty (33) foot LG Wired Remote
Group Control Extension cable (Model No. PZCWRC1).
4. If the cable between the zone controller and the indoor unit is too long, do not cut the cable and shorten. Coil any spare communications
cable, tie-wrap it, and leave it next to the indoor unit location.
