1/2", 2 Way Outdoor Reset I-Series Mixing Valve w/ Sensor
iSeries Mixing Valves
Precise, Cost-Effective Temperature Control for Your Heating Systems
Taco iSeries ® Mixing Valves provide precise and cost-effective temperature control for your heating systems, the flexibility of zone-to-zone control, plus built-in protection against boiler flue gas condensation. Available in 2-way, 3-way or 4-way injection configurations, for either outdoor reset control or fixed water supply temperature applications, and operate off constant power or relay end switch. Features include a ball valve design, High Cv, manual operation button, solid-state microprocessor, multi-status LED indicator light and easy, one-hand actuator removal.

Use the Taco Outdoor Reset iSeries MixingValves instead of a conventional injection system.The iSeries-R is a microprocessor-basedvalve designed to regulate the supply watertemperature to a heating system, based on areset ratio, by modulating the position of aniSeries Mixing Valve, so that the heat suppliedto the building or zone equals the heat lost bythe building.With a full featured outdoor resetcontrol built right into the actuator, there is no need for an externally mounted reset control or expensive control valve.The iSeries-R can also be set up to do zone-by-zone outdoor reset, providing optimal comfort control for every zone.
The direct drive actuator modulates a 2-way, 3-way or 4-way valve that injects different rates of hot water, supplying virtuallyany water temperature to the heating system.Working off an adjustable reset ratio, the valve’s maximum and minimumsystem supply temperatures can be adjusted to support all types of jobs, including staple-up radiant floors thatrequire a higher starting temperature.The iSeries-R includes an adjustable boiler protection function which prevents lowwater temperatures from returning to the boiler.With a multi-status LED indicator light, plug-in wiring connections andan easy to remove actuator, the installation could not be easier.
