Abstract
A sauna having various heating, lighting, or other electrically operated elements is equipped with galvanically isolated current detection circuitry and galvanically isolated voltage detection circuitry, each in communication with a processor. The processor is operable to monitor, store and analyze voltage and current data to detect latent malfunctions and to predict and prevent future malfunctions, and to provide reports to users or operators. In various embodiments the processor may alert users to malfunctions or potential problems and may further actuate circuitry to cut power to the sauna upon detection of a malfunction.
