The Alpha™ is a 115-V circulator for hydronic heating applications in residential and light commercial applications. It has a permanent magnet motor design that will avoid motor slippage problems common to induction-type motors, while delivering a starting torque four times higher than a standard induction motor, says the company. The LED display’s one-touch, button-type interface permits the user to toggle quickly and easily among seven different hydraulic operating modes: three fixed speeds, three levels of constant pressure, and one automatic setting - the AutoAdapt™. The circulator’s sophisticated electronics are fully integrated within the motor, simplifying installation in tight spaces. The large, real-time display alternates readings between energy consumption (watts) and estimated flow indications (gallons per minute). The 6-foot-long Alpha plug connects the circulator to a wall outlet, with no wiring required, eliminating the need to open a terminal box to make electrical connections.
