Abstract:
A spa heater/control includes sensors and processors to monitor and display indicia of common failures. The heater/control includes voltage sensors and processing to measure proper power connections to the heater/control. The spa heater/control further monitors various voltages, currents, flow rates, and temperatures within the spa to provide diagnostic information which is easily obtained by a spa owner to provide to a spa dealer to reduce the time and cost of spa repairs.
