1500ppm (parts per million) of CO2 is the safety limit set in most of Europe
for school classrooms.

Greetings,

I find it hard to believe that the first warning sign of drastically low 
ventilation levels is going to be elevated CO2 levels.

Why not use humidity?  That can be done easily, cheaply, and many 
systems are already configured for it.  Unless you have a CO2 generating 
source which is NOT putting out vastly more H20 than CO2

Thank You Kindly,

Corwyn
