Io Hvac Controls CO2-2POS-10 CO2 Ventilation Kit 10 in

Product Description

The IO HVAC CONTROLS CO2-2POS-10 is a two-position demand-controlled ventilation kit designed for CO2-based airside management in commercial and light-commercial HVAC systems. The kit monitors carbon dioxide levels and drives a two-position actuator to open or close a 10-inch damper based on occupancy-driven CO2 demand. This approach helps maintain acceptable indoor air quality while limiting unnecessary outdoor air intake. The assembly is sized for 10-inch ductwork and ships as a complete kit, reducing the need for separate component sourcing. Licensed HVAC technicians and mechanical contractors are the primary installers.

This ventilation kit is used in demand-controlled ventilation (DCV) applications where CO2 concentration is the control variable. Typical installations include conference rooms, classrooms, gymnasiums, and other variable-occupancy spaces served by rooftop units, air handlers, or dedicated outdoor air systems (DOAS). The two-position control strategy opens the outdoor air damper fully when CO2 rises above the setpoint and closes it when the space returns to baseline, making it well-suited for zones with intermittent or unpredictable occupancy loads.

Key Features

• Two-position CO2-based demand-controlled ventilation for 10-inch duct applications
• Complete kit configuration reduces field assembly time and component mismatches
• CO2 sensing strategy supports ASHRAE 62.1 ventilation compliance in variable-occupancy spaces
• Sized for integration with rooftop units, air handlers, and DOAS equipment
• Package dimensions of 14 inches wide by 9 inches high by 14 inches deep allow for standard shipping and storage

Compatibility

Designed as an OEM-style demand-controlled ventilation solution for 10-inch duct systems in commercial and light-commercial HVAC applications requiring two-position CO2-driven damper control.

Installation Notes

Installation should be performed by a licensed HVAC technician or mechanical contractor familiar with airside controls and low-voltage wiring practices. Shut down the air handling unit and de-energize all associated control circuits before beginning installation. Follow ASHRAE 62.1 and any applicable local mechanical codes for outdoor air ventilation system requirements. Do not energize the actuator or CO2 sensor until all duct connections are sealed and control wiring is verified.
