Titan Controls Atlas 4: 2 Room CO2 Monitor/Controller Questions & Answers

Do I have to have both sensors plugged in if I'm only going to run one room?

Yes, you need both sensors plugged into the Atlas 4 for the product to function properly.

I just plugged my Atlas 4 in and it doesn't provide a 24 hour data logging reading?

The Atlas 4 needs to be functioning for a minimum of 24 hours prior to providing any data logging information. After 24 hours it will give you a CO2 low level, CO2 average level and the CO2 high level for your selected hour. This will allow you to chart your CO2 levels over a 24 hour period and accurately track your CO2 levels.

Does my Titan Controller need to be calibrated?

No, your controller has been factory calibrated and is ready for service when you take it out of the box. Each unit will provide years of use and will maintain its settings without any further changes required.

Are the Titan Controllers compatible with each other?

Yes. They are designed to work together so you may expand your system as needed.

Should I run my CO2 at night?

No, you should not. Plants photosynthesize CO2 only during the daylight hours. At night, the plants expire CO2 and have no use for CO2. Save yourself some money and only dose CO2 during daylight hours when it does the most good for the plants.

What methods can I use to enrich CO2 in my indoor garden or greenhouse?

The two most common methods are using a CO2 generator/burner or bottled CO2. The most common generator/burner uses LP (liquid propane) gas from a tank or a NG (natural gas) conversion kit that allows you to hook up your generator/burner to the natural gas line in your house. The other option is to purchase bottled CO2 from a local supplier in your area and control its release into your garden area using a Titan Controls CO2 controller (Atlas 1) or short cycle repeat cycle timer with photocell. It should be noted that there is no advantage to increasing CO2 levels beyond 2000 PPM for most greenhouse plants. The optimum level of CO2 for plant growth is generally accepted at 1200 - 1600 PPM.
