Taco iSeries® mixing valves are a breakthrough in precision, cost effective temperature control for heating systems. The iSeries® valves are available in two versions, providing either outdoor reset control or fixed water supply temperature by modulating the position of a two way, three way or a four way valve. Additionally, 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.
