Taco I100C3S-1 1″ 3‑Way Setpoint Mixing Valve W/Outdoor Actuator 24V

The Taco I100C3S-1 is a 24-volt outdoor actuator and setpoint controller that may be used in both residential and commercial HVAC systems. By automatically alternating between modes in response to temperature settings that the user has specified, it serves as a central control device for both heating and cooling. This little gadget senses the temperature of its surroundings and is usually installed with Taco's I100 series pumps. It then tells the pump to circulate hot or cold water in order to keep the building at a comfortable temperature. Better temperature control, enhanced economy through optimal pump operation, and easier system administration because of its setpoint controls that are easy to use are just a few advantages of the Taco I100C3S-1.  Replace the broken or worn-out 3-way outside air switch and the Taco pumps' 24V setpoint to maintain optimal system performance.
