The IO HVAC CONTROLS CO2-MOD-06 is a modulating demand-controlled ventilation kit designed for 6-inch duct applications. It monitors carbon dioxide levels in occupied spaces and modulates airflow accordingly, reducing unnecessary ventilation when CO2 levels are low and increasing it as occupancy rises. This type of system is installed by licensed HVAC technicians in commercial and light commercial settings where energy-efficient ventilation control is required. The kit provides a complete assembly for integrating CO2-based demand control into an existing HVAC system without requiring separate component sourcing.
This kit is suited for installation in classrooms, conference rooms, retail spaces, and other occupancy-variable environments where ventilation rates should track actual CO2 load rather than a fixed schedule. The 6-inch configuration fits standard 6-inch round duct systems common in light commercial and larger residential HVAC installations. HVAC technicians and building automation contractors are the primary installers of this type of equipment.
Designed as an OEM-style demand-controlled ventilation solution for 6-inch duct HVAC systems requiring CO2-based modulating airflow control.
Installation should be performed by a licensed HVAC technician familiar with demand-controlled ventilation and building automation wiring. Power down the air handling unit and de-energize all low-voltage control circuits before beginning installation. Follow all applicable local mechanical codes and ASHRAE 62.1 ventilation requirements when commissioning CO2-based demand control systems. Verify duct dimensions and airflow direction before securing the kit in the duct assembly.
