About the size of a quarter, this button sensor replaces the return air sensor on LG cassette and ducted indoor units. It can easily be installed anywhere with its included 49 ft extension cable, and can even be painted over to truly blend in to any room.
Hidden Accuracy
The ZRTBS01 button sensor installs discretely into the wall, barely noticeable but providing accurate temperature readings. It can even be painted over, further masking it from view.
