Titan Controls Atlas 7 – CO2 Controller

The Titan Controls Atlas 7 is a dedicated CO2 controller for indoor grow rooms and greenhouses. It lets growers set a target CO2 concentration — 1000, 1250, or 1500 ppm — and automatically activates a connected CO2 device to maintain that level. An integrated photocell disables CO2 enrichment during dark cycles, and a built-in calibration feature keeps readings accurate over time. Single-button operation keeps setup straightforward. The enclosure is built to resist dust, rust, and moisture, making it practical for the humidity levels typical of active growing environments.

Why Choose the Titan Controls Atlas 7

The Atlas 7 is designed for growers who want CO2 enrichment without the complexity of a fully programmable controller. Here is what makes it a practical choice:

• Three fixed set points keep operation simple. Rather than requiring growers to dial in a precise ppm target, the Atlas 7 offers 1000, 1250, and 1500 ppm as selectable options. These three levels cover the most common enrichment targets for vegetative and flowering stages, so growers can match their CO2 level to their crop without configuring a custom setpoint.
• Integrated photocell prevents CO2 waste during lights-off periods. Plants only use CO2 when photosynthesizing, so releasing CO2 during dark cycles serves no purpose and wastes supply. The Atlas 7’s built-in photocell automatically stops CO2 injection when it detects that lights are off, reducing operating costs and preventing gas accumulation in an unventilated dark space.
• Built-in calibration maintains sensor accuracy over time. CO2 sensors can drift with use. The Atlas 7 includes a calibration feature so growers can periodically verify and correct the sensor reading, ensuring the controller activates at the correct ppm rather than a drifted baseline.
• Single-button control reduces setup time. There is no multi-step menu system to navigate. Growers plug in the controller, select a set point with one button, and the unit is operational. This makes initial setup and future adjustments fast.
• Moisture-resistant enclosure suits grow room conditions. At 0.70 lb, the Atlas 7 is compact and light, and its enclosure is built to handle the dust, humidity, and condensation that are normal in active grow environments — conditions that can degrade less robust electronics over time.

Best Uses for the Titan Controls Atlas 7

The Atlas 7 is suited for grow environments where CO2 enrichment is part of the climate strategy and the grower wants reliable automatic control without complex programming.

• Indoor grow tents and rooms with CO2 burners or tanks. The Atlas 7 connects to a CO2 burner or tank regulator solenoid (up to 5 A load) and cycles it on and off to maintain the selected ppm level. It is a straightforward fit for small to mid-size enclosed growing spaces where a CO2 source is already in use.
• Vegetative and flowering stage enrichment. CO2 enrichment is most effective when plants are actively photosynthesizing under strong light. The three set points — 1000, 1250, and 1500 ppm — map to common enrichment targets used across vegetative and flowering phases, so growers can shift levels as crops progress through growth stages.
• Grow operations that run defined light cycles. Because the integrated photocell automatically suspends CO2 delivery during dark periods, the Atlas 7 works cleanly in any setup running a standard photoperiod. Growers do not need to manually time CO2 delivery around the light schedule.
• Environments where humidity and dust are ongoing factors. The dust- and moisture-resistant enclosure makes the Atlas 7 appropriate for active growing spaces where spraying, transpiration, and airflow move particulates and moisture through the air around equipment. Pair it with an Active Air pedestal fan to maintain good air circulation alongside CO2 management.
• Growers adding CO2 control to an existing lighting automation setup. If a grow room already uses a separate lighting controller — such as the Autopilot PX2 lighting controller — the Atlas 7 can be added independently to layer CO2 management without replacing or reconfiguring the lighting control system.

Compatibility

The Atlas 7 operates on standard North American 120 V / 60 Hz power and is rated for up to 5 A of load current. This is sufficient to switch most CO2 burner solenoids and tank regulator solenoids found in small to mid-size grow rooms. Growers should confirm the current draw of their specific CO2 device against the 5 A maximum before connecting.

The integrated photocell is designed to sense the ambient light level in the grow space. For reliable automatic day/night switching, the controller should be positioned where it receives the same light exposure as the grow area — not inside a cabinet or enclosure that blocks light when the room lights are on.

Because the Atlas 7 is a fixed set-point controller rather than a continuous feedback sensor controller, it is best matched with enclosed grow spaces where CO2 concentration builds predictably. Open or poorly sealed spaces may experience difficulty reaching and holding target ppm levels, which is a function of room sealing rather than the controller itself.

The controller is intended for use with CO2 enrichment devices only. It is not a multi-outlet environmental controller and should not be used to switch lighting, fans, or other climate equipment. Growers managing full room climate automation alongside CO2 enrichment may want to consult Titan Controls’ broader Atlas and Helios controller lines for more integrated solutions.
