Taco 1", 4 Way Setpoint I-Series Mixing Valve (Threaded)

Use the Taco Setpoint iSeries-S Mixing Valves instead of a thermostatic mixing valve for precise dial-in supply water temperature control to a heating system. The direct drive microprocessor-based actuator modulates a 2-way, 3-way or 4-way valve to inject different rates of hot water into the cooler system return water. In combination with the optional boiler protection sensor, the iSeries valves provide the unique benefit of optimal temperature control with boiler protection. The setpoint temperature is adjustable from 80ºF to 180ºF using a dial located on top of the actuator. A 15ºF setback of the supply water can be initiated for additional unoccupied or nighttime setback control. An external multi-status LED indicator light, plug-in wiring connections and an easy to remove actuator makes installation and diagnostics a snap.
