Temperature Sensing Location

Indoor Unit Temperature Sensing Location
To maintain optimal comfort, proper operation and efficiency, considerations should be taken when selecting temperature sensing options.
Choose from one of four methods for temperature sensing, and record what method is used for each indoor unit on the Pre-commissioning
Device Configuration Worksheet.
1. Return air temperature sensor at the indoor unit. Sensing at the return air is the default method. LG indoor units are factory-built with a
return air temperature sensor and do not require a remote controller. For more information, visit www.lghvac.com, and refer to the Engi-
neering and Installation manuals for each particular indoor unit.
2. Use the sensor embedded in the remote controller. (Remote controllers are separate purchases.)
3. Remote temperature button sensor. (Not compatible with wall-mounted indoor units. Temperature button sensor is a separate pur-
chase.)
4. Combination of remote controller with embedded sensor and remote temperature button sensor. When a remote controller is used in
combination with the return air temperature sensor or a remote temperature button sensor, the indoor unit uses the sensed value farthest
from the set point.
Temperature Sensor Location Considerations
• The indoor unit's return air sensor can be used when air is directly returned to the indoor unit without mixing with other sources such as
outside air or open plenum air.
• Temperature sensor should be installed in a location where the temperature of the area is representative of the desired zone temperature,
and in an easily accessible location.
Do not install the temperature sensors in:
• Areas affected by drafts.
• Dead spots behind doors or in corners.
• Areas affected by hot/cold air flow.
• Areas affected by sun or appliances.
• Near concealed pipes or chimneys.
• Unconditioned areas such as an exterior wall
If it is not possible to locate the remote controller in an area that is both accessible and representative of the desired zone temperature, using a
remote controller for control, and a remote temperature button sensor for the sensing location is also an option.
Temperature Sensing Options in a Single Zone—Single Zone, Single Indoor Unit
• A remote controller in an appropriate location is often used, which allows the system to sense the actual temperature that the occupants are
experiencing. (Function Code 4 must be set to 001.)
• If an appropriate location for the remote controller is not available, use the remote controller with a remote temperature button sensor.
Connect the button sensor to the indoor unit and locate it in an appropriate location.
Temperature Sensing Options in a Single Zone—Single Zone, Multiple Units, Group Control
• Using the return air temperature sensor of each individual unit will allow the indoor unit to adjust to the load in its portion of the space.
• Using a remote temperature button sensor with each indoor unit will also allow the indoor unit to adjust to the load in its portion of the
space, and may also better reflect the temperature at the occupant level.
