Dimlux CO2 Regulator what voltage solenoid?

[thingalink]

What voltage solenoid is the Dimlux CO2 Regulator? Or any of the other ones that are meant to be connected to a 'controller'? I would lie ot use my own system so any 12v dc or main co2. regulator recommendations would be grateful.

Cheers

Do not buy that garbage . Advice hit ebay the used market will be cheap !
Brand i like and trust AUTOPILOT. It should have fuzzy logic . Meaning if your using a bottle as you are it keeps the co2 the same level all the time. Never use fuzzy logic if your using a burner . What co2 ppm are you going to use ? I had mine cranked up 2700 More iw better until you start wasting it
Your plants can use heavy co2. Do not listen to the internet saying 1500 nonsense .
One of the best controllers usually is 600 ebay i think you can buy used for 200
