Note:
• Do not bury the wired controller into the wall; burying it may damage the temperature sensor.
• Do not extend the connecting cable >164 feet; overly long cable lengths can cause communication errors.
• When installing the LG-manufactured extension cable, make sure to connect the proper ends together.
Assigning the Thermistor for
Temperature Detection
Each indoor unit includes a return air thermistor assigned to sense the temperature. If a wired controller is installed, there is a choice of sensing
temperature with either the indoor unit return air thermistor or the thermistor in the wired controller. It is also an option to set both thermistors to
sense temperature so that indoor unit bases its operation on the first thermistor to reach the designated temperature differential.
An optional Remote Temperature Sensor can be used in lieu of the return air thermistor—either alone or in conjunction with a wired controller
thermistor as previously described.
