Question about co2 solenoid rapidly cycling on off

[Rtaym22224]

To maintain co2 levels in my space my co2 controller is triggering my regulator solenoid on every ten seconds then off for about ten seconds it rapidly cycles on off. Can the solenoid handle this and is it meant to do this and still function properly without failing?

Something is wrong;

PS: anything will fail quickly/quicker turning on off every 10 seconds; indefinitely… the mechanics demand such

Yes they can handle that but they are limited to x many lifetime cycles. Sounds like you need to spread your on and off target value.

@Rtaym22224 like @Three Berries stated, depending on the controller you have you can adjust your max and min set points. I like to set it a few hundred ppm above my target and my min just below it. Not sure how you are running your rooms but if sealed well then you should be able to maintain your set point for a while.

Can someone tell me how to do this on the atlas 9 controller, the manual is shit and my knowledge of it is almost zero. I would really appreciate it.

I have also been setting a very low constant flow rate and leaving in the on position all day lights on and off when lights off. This is maintaining approx 1600ppm at the lowest flow rate. I may set this back up on my cycle timer and start running it to shorter periods of time every hour, and watching my co2 monitor closely to make sure I’m maintaining proper levels. With the atlas 9 Ppm read out I can do this but will be tricky.

Ideally how do I set up the atlas 9 so it doesn’t cycle on off so often?

Here’s the manual for the atlas 9 controller I can’t figure out

Ok I just calibrated the sensor something I should’ve done to start. I believe I want to set co2 to 1000ppm for example, and then set the dead band to Something like 300 so that co2 turns on when ppm hits 700, off when it reaches a thousand. This should prevent the rapid cycling.

At the moment I’m trying 8 minutes on at a set flow rate 52 minutes off and I’m measuring max/min co2 levels every hour to figure out how to properly dial in the scfh for this space. I may be able to ditch my controller after that, or maybe I don’t want to?

If my solenoid fails will my entire co2 tank dump off all at once? How do I prevent this from ever happening?

Currently using a dirt cheap vivosun regulator. Ordered a $285 pro elite regulator from co2 art. Maybe this will be beneficial to me maybe it won’t? Will it?bought this

if your solenoid gets stuck in the open position yes, you will loose whats in your tank. Some controllers let you set an alarm so if you live where the grow is you can set that and be alerted. I think you have the dead band confused. Without looking over the linked document i remember the dead band always being a number above your set point. ie: set point 1000, dead band set point 200. this will make the controller open the valve till you hit 1200 then as it comes back down to 1000 it will open up again if that makes any sense to ya.

Most solenoid valves are normally off so if it fails electrically it should close or get so weak it can't open enough. How big is the room it's in? 1000ppm isn't worth it. I'm at 1090ppm with the windows shut and AC on right now and just me and the cat 1000 sq foot house.

FWIW they can take lot. Been at +3000 ppm in the winter.
