The 'Professional Series' Kronus 2 controls temperature, humidity and integrates a CO2 system into the grow area at your preferred settings. All the right features in a controller for the indoor gardener!

The Kronus 2 controls temperature, humidity and CO2 in your grow area at your preferred settings. The built in ten (10) minute 'CO2 delay' feature deactivates the CO2 equipment if settings are exceeded by using a digitally based control system. The software polls the temperature and humidity setting ten minutes after the CO2 outlet is defeated to verify that the temperature and humidity are too high, and then activates your exhaust fan, A/C or dehumidifier to lower the conditions under the settings. If the temperature or humidity drops below the set point during the 10 minute 'CO2 delay', then the exhaust/dehumidification process is defeated and the 'CO2 ON' outlet is reactivated, saving your valuable CO2 and keeping it amongst the plants where it belongs.

The Kronus 2 'CO2 ON' feature is only activated during daylight periods to dose CO2 when your plants are able to uptake it and is disabled during the nighttime hours or when the humidity or temperature exceeds the preferred settings.

Plug your exhaust fan, dehumidifier or A/C into the 'Exhaust Fan Output' and plug your CO2 tank with emitter system or CO2 generator into the 'CO2 Output' and you're all set!

Product Q&A

Titan Controls Kronus 2: Temperature & Humidity Controller with CO2 Integration Questions & Answers

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.

What happens to the 'preferred settings' on my Titan Controller if I lose power?

Titan Controls digitally based equipment has 'non-volatile' memory storage that allows the unit to retain settings due to a loss of power. The analog product line settings are not affected by a loss of power and will maintain dial settings.

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.
