Product Instructions

The Atlas 7 CO2 PPM Monitor/Controller takes the guesswork out of maintaining the proper CO2 levels in your garden!

The Atlas 7 can be adjusted to provide 1000 PPM, 1250 PPM or 1500 PPM of CO2 with just a push of a button. When the LED that corresponds with the ambient CO2 level is lit on the controller, it represents the current ambient CO2 level in your grow room. The photocell on the Atlas 7 will react to daytime conditions in your grow area and activate the "output on" LED if required. It will also detect nighttime conditions in your grow area and defeat the power to the Atlas 7.

  • Select Carbon Dioxide (CO2) level at 1000 PPM or 1250 PPM or 1500 PPM with just a push of a button
  • Integrated photocell allows the Atlas 7 to only enrich with CO2 in daylight periods when your plants use it
  • Comes factory calibrated for immediate use
  • ETL listed for use in commercial applications
  • Plastic enclosure resists dust and moisture
  • 5 Amps - 120 Volts - 60 Hz.
  • 1 year warranty

Caution: Sulphur vaporization can damage your controller! To protect your controller, it is important to disconnect and cover the Atlas 7 by wrapping with a plastic bag OR remove the controller from the grow area while using sulphur vaporizers in your grow room.

Titan Controls Atlas 7: CO2 PPM Controller Questions & Answers

What it the correct CO2 PPM level for my garden?

The Atlas 7 addresses that question well. It was developed based on common CO2 levels that most customers want to achieve in their grow rooms. The 1000 PPM/1250PPM/1500 PPM preset levels allows the user to get the most out of their CO2 system while providing their plants with just the right amount of CO2! Try the Atlas 7 at the different CO2 levels and see how your garden grows!

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.

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.

Why do gardeners enrich their growing space with CO2?

CO2 is proven to speed up a plants growth rate, improve overall health and increase a plants yield. There are also many other benefits to plants, among them greater resistance to temperature extremes and other forms of stress, better growth at low light intensities, improved root/top ratios and less injury from air pollutants.

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.
