Hi BFuddled,

Kele has a device (UCS-121 or UCS-221) that does this trick, and if you need to scale the input, there is a UAT-1 that can do that too.

Have a look, the web is

http://www.kele.com,

and it's in the product catalog under output transducers.

Let me know if you need more info.

Dave,
I know this was thread was a while back, but I have a question for you. BFuddled wanted to turn ON at a set voltage then OFF again at another voltage. I too want the same thing. I want to come ON at between 3.5vdc and 5vdc, anything above or below I want to be OFF. Question: Will the UAT-1 you mentioned accomplish this? I have read the docs from KELE, but I'm afraid I just don't understand the lingo enough to know if it will. If it isn't too much trouble for you, could you please let me know if it will do what I described?
Thanks!
Moon

Well guys I promised to give an update when I got it all put together..... So

The UCS-221 controller finally showed up. It was pretty simple to calibrate. Since I already had the Solid State Relay and had it wired and mounted in my control box, I just used the controller board with the 24vdc power supply to trigger the relay instead of wiring the regulator direct to the board. I simply plugged the control board power supply into a timer to ensure it doesn't activate the CO2 at night. I've had it in operation for the last 24 hours and thus far it seems to functioning perfectly! It maintained 1100-1300 ppm all day yesterday. I went out around 9pm last night to checked in to find the levels had dropped to about 600 ppm, just as expected. I went out and checked this morning and the system powered up as intended and the ppm levels are about 1200. I couldn't be more pleased.

Dave, Thank you VERY much for all your help on this project. And I want to thank everyone for all the useful input. I'm very grateful.

Since my last post I have been doing considerable research into the computer controlled concept.... I'm very intrigued by this, and want to begin designing the system. So, I will likely be back with more dumb questions

Cheers!
Moon
