This simple yet efficient Temperature Limit Controller (TLC) offers substantial energy savings on your Air Conditioning by limiting the `Set Temperature'. Turns your compressor on/off as per adjustable temperature limits. The TLC is compact and easy to install on any existing AC system by connecting it to the compressor relay line. The TLC overrides the AC control system and can limit the Cool/Heat set points. Limit values are configurable. If ambient temperature from the return air sensor exceeds the predefined limits, the compressor will stop working. The TLC will automatically re-operate the compressor according to these values. The TLC allows significant energy saving in both commercial and residential applications while investment is minimal.
