vetilation/co2 question

i have my environmental controller set up so that my fan turns on and my co2 turns off when the temp reaches 86-87f
the thing is, the temp never goes over 80f so my fan never goes on and the co2 stays on constantly. i plugged the fan into the night device outlet so the co2 stays on all day and the fan runs all night.
is it ok for the room to go without ventilation all day (12hrs)?

You want to exchange the air in your room at least once every hour.
So the answer to your question would be, No.
You don't want the Co2 to be on all the time either.
You must be going through a shit load of Co2.

i know i bought a mechanical timer so i could have the co2 on like 15min every hour or something. by then screwed the environmental controller on the wall and the way the outlet on the side of the controller was facing, the timer couldnt plug into it.
