i100U3S-1 iSeries Mixing Valve, Setpoint, 3-Way, 1" Sweat Union Connection

Taco iSeries Mixing Valves are a breakthrough in precision, cost effective temperature control for heating systems. The iSeries valves protect the boiler against flue gas condensation. A microprocessor-based control is built into the valve actuator, to which all wiring connections are made. All-in-one iSeries Mixing Valves deliver optimum zone-by-zone temperature control, with built-in boiler protection.

Use the Taco Setpoint iSeries Mixing Valves instead of a thermostatic mixing valve for precise dial-in temperature control to a heating system. 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 80 F to 180 F using a dial located on top of the actuator. A 15 F 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.
