SmartPlus ® Hot Water Recirculation can save up to 12,000 gallons of water each year and reduce electrical consumption up to 94% when compared to traditional continuous run domestic hot water recirculation pumps. The SmartPlus ® has all the features and functionality of the original design with the addition of the following new and exciting features: Adjustable Run Time The SmartPlus ® Hot Water Recirculation incorporates an adjustable dial located on the circuit board. This new feature enables the pump’s run time to be set anywhere between 1 to 10 minutes. This adjustable run time optimizes the pump’s cycle timing to fit system requirements. In systems with shorter runs of piping the SmartPlus ® Hot Water Recirculation can be set to cycle for a shorter period of time. For larger systems with longer runs of piping the SmartPlus ® Hot Water Recirculation can be set to cycle for a longer duration of time to provide optimal hot water comfort when it’s needed. 72 Hour Memory Backup In the event of a power outage the new SmartPlus ® Hot Water Recirculation retains its internal timer and all recorded hot water usage data will be saved for 72 hours. When power is restored, it will automatically return to its normal operating mode providing hot water when it is needed. Automatic Operation Smart Mode – The SmartPlus has two operating modes – “Smart” or “Pulse”. Set the control board toggle switch to the desired mode and the SmartPlus does the rest! The pump never needs to be reset and NO TIMER OR AQUASTAT IS REQUIRED to control pump operation. Hot water is always available in seconds. How the SmartPlus Circulator Works Using state-of-the-art electronics, the SmartPlus® Hot Water Recirculation will monitor and record the home’s hot water usage pattern for the first 7 days of operation. For the next 7 days, the SmartPlus ® Hot Water Recirculation repeats the preceding week’s usage pattern to cycle the pump, providing instant hot water at all fixtures only when needed. This process will be repeated every week. Pulse Mode – An optional “Pulse” mode can be selected which sets the SmartPlus to run for the preset duration every 10 minutes maintaining hot water at all fixtures. Vacation Function After 36 hours of inactivity the pump will automatically TURN OFF and remain off until hot water usage is detected again. Exercise Function While in vacation mode the pump will cycle on once every 7 days and run for 10 seconds to prevent any corrosion or scale buildup.
