The Taco iSeries® 3-Way Outdoor Reset Mixing Valve (MPN: I075C3R-1) is an all-in-one microprocessor-based temperature regulation valve engineered for maximum hydronic fuel savings.

Advanced Algorithmic Performance Elements:

  • Built-In Outdoor Reset Logic: Houses a full-featured outdoor reset control directly inside the actuator head, continuously adjusting the heating system loop's water temperature to match the building's shifting real-time heat loss.
  • Integrated Boiler Shock Prevention: Actively monitors boiler return water parameters and dynamically modulates down to guard the heat exchanger against devastating low-temperature boiler flue gas condensation.
  • High-Flow Leak-Free Ball Valve: Replaces low-performing thermostatic alternatives with a heavy-duty, direct-drive ball valve design that provides a high Cv rating and complete drop-tight shut-off up to 125 PSI.

Technical Diagnostic Elements:

  • Multi-Status Diagnostic LED: Embedded exterior indicator light gives rapid visual confirmation of system call states, sensor faults, or warm weather shutdown status.
  • One-Hand Actuator Serviceability: Features a tool-free quick-release assembly that allows the motorized control head to be detached from the brass body with one hand in seconds.
