Setpoint Application:
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 initi-
ated 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.

Outdoor Reset Application:
Use the Taco Outdoor Reset iSeries Mixing Valves instead of a conventional injection system.
With a full featured outdoor reset control built right into the actuator there is no need for an
externally mounted reset control or expensive control valve. The iSeries valves can also be set
up to do zone-by-zone outdoor reset, providing optimal comfort control for every zone.
New 3-way iValve with union connections makes for an easy change-out of any thermo-
static mixing valve. Instantly improve the comfort and energy efficiency of any job by
dropping in an Outdoor Reset iValve in place of any fixed temperature mixing valve.
The direct drive actuator modulates a 2-way, 3-way or 4-way valve that injects different rates
of hot water, supplying virtually any water temperature to the heating system. Working off an
adjustable reset ratio, the valve’s maximum and minimum system supply temperatures can be
adjusted to support all types of jobs, including staple-up radiant floors that require a higher starting
temperature. The iSeries valves include an adjustable boiler protection function which prevents low
water temperatures from returning to the boiler. With a multi-status LED indicator light, plug-in
wiring connections and an easy to remove actuator, the installation could not be easier.
