Most ventilation codes and regulatory organizations (ASHRAE – American Society of Heating, Refrigerating and Air-Conditioning Engineers) recommend rooms be at their maximum ventilation rates when CO2 levels reach 1000 ppm. While anytime a room is below 1000 ppm, ventilate can be at a minimum rate ( both of these rates are determined by professionals trained on local ventilation codes).

Pelican default CO2 Ventilation configuration is 800 PPM because we believe that you should begin increasing the ventilation rate before reaching 1000 PPM. This makes Pelican’s ventilation adjustments more dynamic, instead of just going from the minimum to maximum ventilation positions as CO2 levels move.
