Wall-Mounted Sensor Installation; Wall-Mounted Controller Installation - LG Multi V Installation Manual

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
controller 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 of for 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

Floor standing indoor units can be used with various wired controllers (optional; sold separately). Because the room temperature sensor is
inside the remote controller, the remote controller should be installed in a place away from direct sunlight, high humidity and direct supply of
hot or cold air to maintain proper space temperature. Install the remote controller about 5 feet 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
• An area where temperatures are uncontrolled, such as an outside wall
Remote controllers are equipped with a seven segment LED display. For proper dis-
play of the remote controller LEDs, the remote controller should be installed properly
as shown. The standard height is four (4) to five (5) feet 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-three (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-three (33) foot LG Wired Re-
mote Group Control Extension cable (Model No. PZCWRC1).
4. If the cable between the zone controller and the indoor unit is too long,
cut the cable and shorten. Coil any spare communications cable, tie-wrap it, and
leave it next to the indoor unit location.
