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.

LG PREMTA200 Deluxe Manual: Questions and Answers

Can I use the LG PREMTA200 Deluxe if temperature readings don't match the actual room temperature?

Temperature discrepancies can occur if air from unconditioned spaces enters through the mounting plate openings. Seal unused openings with the supplied foam donut or insulating material, and upgrade firmware to version 1.006 or higher. User Guide, p. 1

What does it mean when the LG PREMTA200 displays a different temperature than the room actually is?

External air movement inside the wall cavity can affect the displayed temperature. This happens when cable entry holes or mounting plate openings aren't sealed properly. User Guide, p. 1

How do I seal the cable entry hole on my LG PREMTA200?

Block the opening using the LG-supplied foam donut or field-supplied insulating material or tape. User Guide, p. 1

What do the securing screw and cable guides on the LG PREMTA200 Deluxe backplate do?

The screw locks the controller to the backplate to prevent accidental dislocation. Cable guides route the IDU to remote controller cable properly along the backplate. User Guide, p. 2

−10°F to 10°F (−5°C to 5°C). User Guide, p. 5
