The IO HVAC CONTROLS q5-no2-10p-0-a is a nitrogen dioxide (NO2) sensor designed for air quality monitoring in HVAC and ventilation applications. Nitrogen dioxide is a combustion byproduct that poses serious health risks at elevated concentrations, making reliable detection critical in occupied spaces. This sensor is installed by licensed HVAC technicians as part of demand-controlled ventilation or indoor air quality monitoring systems. It detects NO2 levels and provides a signal output that integrates with compatible HVAC controls, allowing the system to respond to changing air quality conditions.
The q5-no2-10p-0-a is suited for residential applications where indoor air quality monitoring is required. Typical installation scenarios include homes with attached garages, residences near high-traffic areas, or any dwelling where combustion appliance exhaust or vehicle emissions may introduce NO2 into occupied living spaces. HVAC technicians integrate this sensor into ventilation control sequences to help maintain safe indoor air quality levels.
Designed as an OEM-style replacement or add-on NO2 sensing component for residential HVAC and ventilation control systems.
Installation should be performed by a qualified HVAC technician familiar with low-voltage sensor wiring and indoor air quality control systems. Power down the control system before making any wiring connections to the sensor. Follow all applicable local codes and the control system manufacturer wiring guidelines when integrating this sensor into a ventilation sequence. Avoid installing the sensor in locations subject to direct airflow from supply registers, as this can cause inaccurate readings.
