The 0018e high-efficiency, Bluetooth-enabled circulator brings a new level of control to residential and light commercial hydronic systems. The ECM-powered 0018e is a solution for contractors who want the durability, efficiency and simplicity of other Taco ECM circulators, while looking for more system feedback and control than has been previously available. The circulator communicates to a mobile app, providing real time control, diagnostics and reporting. Installers can select between multiple constant speed, proportional pressure and constant pressure modes as well as activeADAPT, Taco’s self-adjusting proportional pressure mode. The circulator qualifies for most state, regional and utility efficiency incentive programs, the company notes. Taco Comfort Solutions.
