Indoor Air Quality & Ventilation Control

The built-in CO2 sensor continuously monitors carbon dioxide concentrations in the conditioned space. When CO2 levels rise — indicating increased occupancy — the thermostat signals the HVAC system to increase fresh air intake. As occupancy drops and CO2 levels normalize, ventilation is reduced, saving energy without sacrificing air quality. This makes the CS8500 an ideal solution for meeting ASHRAE 62.1 ventilation standards in occupied spaces.
