Io Hvac Controls SC-SPC-800 Static Pressure Controller

Product Description

The IO HVAC CONTROLS SC-SPC-800 is a static pressure controller designed to monitor and regulate duct static pressure in HVAC air distribution systems. It maintains setpoint pressure by modulating variable air volume (VAV) equipment, fan drives, or dampers in response to measured duct conditions. The unit measures 4.25 x 3.625 x 4.25 inches and weighs 0.5 pounds, making it compact enough for tight mechanical room or air handler installations. Licensed HVAC technicians and controls specialists install this device as part of building automation and zoning control strategies where consistent duct pressure is critical to system efficiency and airflow balance.

The SC-SPC-800 is suited for commercial and residential HVAC systems that require active static pressure management. Typical applications include variable air volume air handling units, supply duct zoning systems, and fan modulation setups where duct pressure must be held within a controlled range to protect equipment and maintain comfort. It is installed in-line with duct pressure sensing components and wired into the control circuit of the air-side equipment being modulated.

Key Features

• Compact enclosure at 4.25 x 3.625 x 4.25 inches fits tight mechanical installations
• Designed for active static pressure regulation in ducted HVAC systems
• Lightweight at 0.5 pounds for easy panel or wall mounting
• Compatible with VAV, fan speed control, and damper modulation strategies
• Purpose-built for trade installation by qualified HVAC controls technicians

Compatibility

Designed as an OEM-style static pressure controller for use in ducted HVAC air distribution systems requiring active duct pressure management and fan or damper modulation.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage controls and duct pressure sensing. Disconnect and lock out all power to the air handling unit and control panel before wiring. Mount the controller in a location free from excessive vibration and connect the pressure sensing tubing to the supply duct at the recommended sensing point per system design. Verify all control wiring complies with applicable local codes and NEC requirements before restoring power and commissioning.
