Taco’s SmartPlug optimizes hot water system efficiency and reduces electrical consumption up to 94%. In the “Smart” mode, it monitors and records weekly household hot-water use patterns and adjusts HWR cycles accordingly. The device offers an optional “Pulse” mode. In this setting, the circulator will cycle on and off to maintain hot water at all fixtures. After 36 hours of inactivity, the device automatically turns off the pump until a need is detected; it also cycles on once every seven days for 10 seconds to prevent corrosion or scale buildup
