AC Infinity CO2 Controller | Smart Outlet Carbon Dioxide Monitor for CO2 Regulators and Inline Fans

Precision Control in Any Space

Every unmonitored hour inside a sealed grow environment is an hour where CO2 concentration drifts unchecked — spiking when equipment stacks, crashing when ventilation runs blind, and settling into a range that costs yield without ever triggering an alarm. Manual correction cycles mean the operator is the sensor, the timer, and the actuator simultaneously. That is not a workflow — it is a liability. The silent cost is not one bad run; it is the compounding variance across every run, every cycle, every season, while the root cause stays invisible because no instrument is closing the loop.

After the AC-CTC7 is deployed, the atmospheric correction loop runs without operator presence. CO2 concentration is continuously sampled, set-point thresholds are enforced in real time, and the two outlet channels respond independently — one triggering the CO2 regulator when PPM drops below target, the other activating the exhaust fan when PPM climbs above ceiling. Schedules and alarms hold the environment accountable across every light cycle. Historical high and low PPM data accumulates on-device, giving the operator a verifiable record of atmospheric performance rather than a guess.

The mechanism behind that outcome is a next-generation photoacoustic CO2 sensor — a measurement technology that uses acoustic resonance to detect CO2 molecular concentration with a resolution of 1 PPM below 1000 PPM, 5 PPM between 1000 and 2000 PPM, and 10 PPM above 2000 PPM, across a measurement range of 0–5000 PPM. The sensor probe cord extends approximately 6 feet for remote canopy-level placement, while the controller's 53-inch (4.4-foot) power cord allows wall-mount positioning via the integrated keyhole hanger. The two standard 120V outlets are independently programmed — CO2 regulator on one channel, exhaust fan on the other — with CO2 trigger, fan trigger, and cycle programming modes operating in alternating logic to dynamically raise or lower atmospheric concentration. The LCD display with blue LED backlight surfaces outlet power status, CO2 trend direction, clock, and cycle data at three manual brightness levels plus two auto-dimming levels, and an internal clock battery sustains scheduling through power interruptions. In practical terms, the AC-CTC7 enforces CO2 set-point control across a 0–5000 PPM measurement range through a photoacoustic sensor, driving up to 1100W (10A) of connected load across two independently programmed 120V outlets from a standard 100–240V input.

Where This Belongs (and Doesn't)

The AC-CTC7 controls outlet switching based on CO2 set-point logic. It does not replace dedicated HVAC controllers, high-voltage circuit management systems, or multi-zone atmospheric automation platforms. Verify that connected devices do not exceed 1100W (10A) total load. Consult a licensed electrician before integrating into any facility electrical circuit that requires load balancing or dedicated breaker allocation.

How It Works

The AC-CTC7 operates as a closed-loop atmospheric control node. The photoacoustic CO2 sensor — mounted remotely via its probe cord — continuously samples the air column and transmits concentration data to the controller's processing cortex. Photoacoustic technology works by directing modulated infrared light through a gas sample chamber; CO2 molecules absorb the light and generate a pressure wave proportional to their concentration, which the sensor converts into a precise PPM reading. This method produces fast, stable readings without the drift characteristics associated with older electrochemical or NDIR sensor architectures.

The controller's dual-outlet module operates on independent programming logic. Outlet 1 is assigned to the CO2 regulator: when measured PPM falls below the operator-defined set-point, the outlet activates, opening the regulator and injecting CO2 until the target concentration is reached. Outlet 2 is assigned to the exhaust fan: when measured PPM exceeds the upper threshold, the outlet activates, purging excess CO2 until the concentration returns to range. The two channels alternate in response to live sensor data — they do not run simultaneously — ensuring that injection and exhaust do not work against each other. Cycle programming adds a third layer of control, allowing timed activation sequences independent of PPM triggers for ventilation scheduling during lights-off or CO2-off periods.

The LCD display with blue LED backlight presents outlet power status, real-time CO2 PPM, trend direction, clock, and active cycle data on a 2.53 x 2.98 in. (6.43 x 7.57 cm) screen. Display brightness is operator-selectable across three manual levels and two auto-dimming levels. Historical data logging captures high and low PPM thresholds over time, providing a verifiable atmospheric record for each production cycle. The internal clock battery sustains time and scheduling data through power interruptions, preventing schedule loss during facility power events. The housing measures 2.95 x 4.72 x 1.10 in. (7.5 x 4.72 x 2.8 cm), constructed from hard black fire-resistant plastic, and mounts via keyhole hanger with included wood screws. The 53-inch (4.4-foot) power cord connects to a standard 100–240V wall outlet, and the sensor probe cord extends 144 inches (12 feet) — with the sensor cable itself approximately 6 feet — for flexible canopy-level placement independent of controller mounting position. In practical terms, the AC-CTC7 delivers photoacoustic CO2 measurement at 1 PPM resolution across a 0–5000 PPM range, switching up to 1100W (10A) across two independently programmed 120V outlets from a 100–240V input source.

Facility Integration Data

The following ROI framework is provided for operators evaluating the AC-CTC7 as a standardized atmospheric control node across multi-unit facility deployments. Labor savings are estimated based on elimination of manual CO2 monitoring and ventilation adjustment cycles; actual results will vary by facility protocol and staffing structure.

Operator Field Notes

• Sensor placement determines measurement accuracy: Mount the photoacoustic probe at canopy level — not at ceiling height — to capture the CO2 concentration your plants are actually experiencing. The approximately 6-foot sensor cable provides enough reach for most tent and room configurations when the controller is wall-mounted at a practical height.
• Outlet assignment is not interchangeable mid-cycle: Outlet 1 is the CO2 trigger channel; Outlet 2 is the fan trigger channel. Reversing device connections after programming is complete will invert the control logic. Label your cables at installation.
• CO2 range data conflict — verify before setting upper thresholds: Source data shows a conflict between the product page listing (0–10,000 PPM) and the manual specification (0–5000 PPM). Treat 5000 PPM as the verified operational ceiling until AC Infinity confirms the upper range. Do not program set-points above 5000 PPM without manufacturer confirmation.
• Cycle programming is independent of PPM triggers: The cycle mode allows timed activation sequences that run regardless of current CO2 concentration — useful for lights-off ventilation schedules where CO2 injection is suspended but air exchange must continue.
• Internal clock battery is not user-replaceable in the field: The battery sustains time and schedule data through power interruptions. If the clock loses time after extended power loss, contact AC Infinity support — do not attempt to open the housing to replace the battery without manufacturer guidance.
• Total load ceiling is 1100W (10A) across both outlets combined: Do not treat each outlet as independently rated to 1100W. The controller's maximum supported power is 1100W total. Size your connected CO2 regulator and fan accordingly.
