The TK-RE02 Temperature Remote Controller has two functions. It allows the output temperature from the T-KJR to be adjusted within the range of 99 °F to 182 °F, and it also works as a diagnostic tool that will give a concise error code whenever there is a problem with the unit.
The temperature options are 99°F, 100°F, 102°F, 104°F, 106°F, 108°F, 109°F, 111°F, 113°F, 115°F, 117°F, 122°F, 131°F, 140°F, 158°F, and 167°F or 182°F.
