Co2 Controller

Hi I purchased a C.A.P AIR-3DN controller and I am trying to set up my co2 tank and my exhausts to the controller. I can't seem to get the controller to time the amount of time the co2 is being dispensed and then turn back on the exhausts. I have my day temp set to 76 and my night temp set to 67. Everytime I turn the day temp past 73 the co2 turns on and the exhausts turn off, however the co2 does not turn off it just keeps dispensing and the exhausts never turn back on unless I turn down the temp to below 73. Does anyone have any insight into this controller that could help me out at all, any help is appreciated thanks.

what size is your area u are trying pump the co2 in
anything that is smaller then a 10x10x7 u do not use a controller ..........u use a timer

It's a garage and I have divided it in half so it's about 13ft by 9ft by 8ft
ok buddy
your size is big enough to use a controller but a tank is not a good idea i should invest into a a Burner (the tank willl empy faster then a burner )

2nd thing the walls u made did u polywrap them to seal the room or to make a tub

Why NOT use a controller?
because u can do the same thing as a controller with a timed release ............a area under 10x10 is small so they only need a regulator that release 0.2 to 2 cf
here is mine
my area natural ppm is near 500 ..........to raise my area to near 1500 i need to release 0.2 cf for 45 mins it raise my ppm to 1500
here is a calu to help
https://www.hydroponics.net/learn/co2_calculator.asp
that give u the basic info ........run time on a 20 lb tank or a 5 lb propane tank

this one has a natural ppm part

if u run the numbers u will see the flow rate is under 2 cf ............when u go above a 10x10 u need to use a regulator that is 0.5 to 15

Day temp with co2 at 76F ? You may as well not be running the co2. up temps to mid 80s .

and return the controller and get something better, Cap blows.
Throw for a ppm controller. Take all the guess work out.

I cut my co2 consumption by 1/2 using a controller instead of a timer. From 1 X 20lb tank every 3 weeks to I'm still running on the same tank Since Feb 8........ Timers don't account for leakage or consumption, you have to guess how often to release co2

What I need is a thermostatic controller with adjustable deadzone. Cap certainly doesn't see a use for deadzone but I do.

The atlas 3 I like but it doesn't control exhaust, so I have my exhaust hooked up to a shitty cap air 4 and my titan atlas 3 hooked up to the co2 outlet on the cap. I know this isn't ideal because it powers the atlas 3 on and off which I don't like but it's the only solution I've come up with to cycle fan and co2.
