IO Hvac Controls iO-SPC Pressure Control
The iO HVAC Controls iO-SPC is a professional-grade static pressure controller designed to manage airflow within zoned HVAC systems. Engineered with a solid-state switching and timing circuit, this unit enhances system reliability by providing precise control over bypass dampers equipped with floating-type actuators. As individual zone dampers modulate, the iO-SPC monitors the supply plenum pressure, automatically adjusting the bypass air to maintain a consistent static pressure setpoint. This prevents excessive air velocity and noise issues often associated with high-static conditions in residential or light commercial ductwork.
Featuring a fully-calibrated setpoint dial, this floating actuator controller allows for rapid field setup across a pressure range of 0.08÷ to 1.20÷ WC. The 1/4÷ I.D. flex hose connection and included sensing probe ensure accurate readings when installed at least 3 feet downstream from the air handler. Designed for vertical mounting, the iO-SPC includes LED status indication to signal when the damper is driving open, ensuring contractors can perform visual diagnostics and HVAC duct pressure testing with ease. This 24V pressure switch is built for durability, withstanding operating temperatures from -40? F to 190? F in demanding plenum environments.
Key Benefits- Precise Pressure Regulation: Maintains a constant static pressure (CFM) by modulating the bypass damper, preventing high-velocity air noise.
- Enhanced Reliability: The solid-state timing circuit eliminates the wear associated with mechanical relays, ensuring a longer service life.
- Simple Calibration: Includes a fully-calibrated dial allowing for intuitive adjustments without the need for high-end manometers during basic setup.
- Complete Install Kit: Shipped with a sensing probe, mounting hardware, and plastic tubing for immediate field integration.
- Universal Compatibility: Works seamlessly with most floating-type motorized actuators for versatile application in HVAC zoning projects.
How do I adjust the pressure setpoint for a small zone?
Confirm the system is balanced and the fan is at full speed. Use the setpoint adjustment knob to increase or decrease the static pressure until the bypass damper relieves enough air to eliminate noise at the registers while maintaining sufficient airflow to the calling zone.
Where should the sensing probe be installed?
The probe must be inserted into the main supply plenum, at least 3 feet downstream of the air handling unit and past the bypass duct. Ensure the arrow on the probe is pointing in the direction of airflow for accurate readings.
Can this controller be mounted in any orientation?
No, for the internal diaphragm to function as calibrated, the iO-SPC must be mounted vertically. Mounting the controller horizontally can lead to inaccurate pressure switching and system instability.
