The Alpha™ circulator has a permanent magnet motor design and a patented AutoAdapt™ feature, which controls pump performance automatically within a defined performance range, ensuring the lowest possible energy consumption without sacrificing comfort. The Alpha circulator with a terminal box option is designed for conduit connection applications. According to the manufacturer, most pumps have only one option when it comes to their power connections, but users are now free to use the existing conduit connection, as long as it is feasible and safe. For new installations, users have the flexibility to use either the circulator with a terminal box or the circulator plug with line cord, which requires no wiring and offers an easy connection. The replaceable terminal box, with two-hole conduit access, uses the manufacturer’s standard pushpin power terminal connections.
