PREMTA200 updates for improved temperature control  

Affected Product(s):  

Applicable Models:  

Affected Date(s):  

LG PREMTA200 deluxe thermostat  

Firmware versions prior to 1.006  

Manufactured before March 2023  

Description:  

When the LG PREMTA200 Controller is installed, there may be temporary or persistent discrepancies between the actual  

room temperature and the temperature displayed.  

Information:  

During the operation of the LG PREMTA200 product manufactured before March 2023 with firmware versions  

prior to 1.006, external influences can affect the temperature displayed on the installed remote controller.  

Discrepancies between actual room temperature and displayed room temperature can occur if there is ingress  

of air from an unconditioned space via the openings of the mounting plate of the PREMTA200 Controller. It is  

important to seal the unused openings of the PREMTA200 backplate using the foam donut supplied with the  

PREMTA200 or using field supplied insulating material. It is also recommended to upgrade the current  

firmware version to 1.006 or above, as shown below.  

If an electrical junction box is utilized for the controller mounting, be sure to use an alternate backplate adaptor,  

not provided by LG, or other means to block off the junction box opening. Recommended IDU to Remote  

Controller cable should be properly routed on the backplate of the PREMTA200 using the pathway and cable  

guides in the backplate.  

The procedure for updating firmware and functions:  

1. Block the cable entry hole with LG-provided foam donut or field supplied insulating material as shown below  

to avoid temperature variations by air movement inside the wall.  

1.1 Installed remote control.  

1.2 Pull the lower part of the remote  

control. Detach the remote control.  

1.3 Block the cable entry hole with LG-supplied  

foam donut or field supplied insulator or tape.

• Page 2: Once the PREMTA200 backplane is secured to the wall and associated cable terminated, the PREMTA200 controller can be mounted on and clipped into the backplate as shown. A securing screw may be used to effectively ‘lock’ the PREMTA200 controller into the backplate, thereby avoiding accidental dislocation of the controller. Remote controller can be locked to backplate with a screw as shown. Controller shown with a sealed back plate and mounted flush to the wall. Update firmware to version 1.006 or higher. Preparation: OTG Cable (USB to micro 5pin), USB Memory, Update Files (Target version). Copy “Update Files” into the USB Memory. “Update Files” to be added under the “rrcUpdate” folder of the USB Memory. PREMTA200 updates for improved temperature control.
• Page 3: To obtain the most current version of firmware, contact the LG Field Support Specialist for your region. Check SW version of RRC (Deluxe Wired Remote Controller). Open the RRC bottom cover and connect the OTG cable to the Micro USB port. PREMTA200 updates for improved temperature control.

• Page 5: Remote controller will automatically restart after update completion. Disconnect OTG cable from RRC when LG logo appears, check the updated version at the bottom right. For the temperature deviation according to the installation environment, use the temperature compensation in the installer setting. On initial power up, please allow 10 minutes prior to applying any temperature compensation available in the advanced installer settings. How to enter setting: Menu -> Installer setting -> Air conditioner -> Temperature Offset. The password for installer settings is the version of the remote control. Example: If the remote-control version is 1.006, the password is 1006. PREMTA200 updates for improved temperature control.
• Page 6: After selecting an air conditioner, use the temperature compensation function. Temperature calibration works only when the temperature sensor reference is selected with the remote control. Temperature compensation can be set to -10F to 10F (-5℃ to 5℃) to match the space temperature. If temperature fluctuation continues, it is recommended that the PREMTA200 Controller be replaced with a current production model with firmware version 1.006 produced after March 2023. To obtain the most current version of firmware, contact the LG Field Support Specialist for your region. Always refer to the LG Installation and Operations Manual (IOM) for additional instructions prior to PREMTA200 Controller. Good installation practices are essential when installing wall mounted controllers/thermostats/sensors to properly sense and control temperature. Location, installation, and setup of room controllers is extremely important to occupant comfort and system performance. Room Controllers should be located in a central location away from doorways, windows, diffusers, or other sources of thermodynamic heat or cold.
