Caution: Sulphur vaporization can damage your controller! To protect your controller, it is important to disconnect and cover the Atlas 4 by wrapping with a plastic bag OR remove the controller from the grow area while using sulphur vaporizers in your grow room.  Titan Controls can analyze and detect CO2 components that have been contaminated & damaged by sulphur vaporization.  We reserve the right to not repair these defective units under warranty, however we can repair & return your Atlas 4 for a fee, if you'd like

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

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

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

A: 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.

Q: Does my Titan controller need to be calibrated?

A: 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.  Please contact us if you think that your calibration is not correct and we can help you out.

Q:  My CO2 monitor/controller is reading really high all the time.  What's wrong with it?

A:  We hear this a lot.  The main issue is the 2000 ppm of CO2 we exhale when we're breathing.  If you're in your room and you see that the ppm is high, leave the area for an hour or so and turn off your CO2 source, then peek your head in and check the reading, it should be reading under 1000 ppm mattering on how well your room is sealed.  After observing your CO2 Monitor/Controller for awhile, you'll start to see what your normal ppm level is in your room.  The normal outdoor ppm is 400 ppm to 600 ppm based on where you live (city vs. rural).

Q:  Should I run my CO2 at night?

A:  No, you shouldn't.  Plants photosynthesize CO2 only during the daylight hours.  At night, the plants expire CO2 and have no use for CO2.  So, save yourself some money and only dose CO2 during daylight hours when it does the most good for the plants.
