Commercial Instruments CO2 Controller

Commercial Instruments CO2 Controller – Model AWG610 The Commercial Instruments AWG610 is a simple, accurate digital CO₂ monitor and controller designed for grow rooms and controlled environments. It continuously measures CO₂ (PPM) and can automatically control a connected CO₂ device to maintain your target level. A large, easy-to-read LCD screen displays CO₂ concentration, temperature, and humidity, with 1 PPM display resolution for precise monitoring. The AWG610 includes a remote sensor unit (with hook for hanging at canopy height) and supports both Plant Mode and Human Mode, making it useful for cultivation control or general CO₂ level monitoring with alarms. Key Features Low-drift NDIR CO₂ sensor High precision temperature & humidity sensor Large LCD display showing CO₂, temperature, and humidity Plant Mode / Human Mode selection Built-in Day/Night photocell sensor (Plant Mode) Adjustable CO₂ setpoint Adjustable deadband control CO₂ MAX/MIN memory display + reset Alarm + relay trigger in Human Mode Manual outdoor calibration function Plant Mode (Grow Room Control) In Plant Mode, the AWG610 uses its built-in photocell to detect day vs night.This allows it to automatically stop CO₂ output during darkness (when plants aren’t using added CO₂ efficiently), and resume control when light is detected. Human Mode (Alarm & Safety Monitoring) In Human Mode, the unit provides CO₂ alarms with adjustable thresholds: AL1 default: 800 PPM (adjustable 800–2500 PPM, steps of 100 PPM) AL2 default: 2600 PPM (adjustable 2600–5000 PPM, steps of 100 PPM) When CO₂ rises above AL1, the buzzer sounds intermittently and the relay is triggered. If CO₂ rises above AL2, the alarm becomes more urgent. ⚠️ Disclaimer: This device is not intended for workplace hazard CO₂ monitoring or medical/life-sustaining use. Setpoint & Deadband Control… You can set a target CO₂ level using SETPOINT, and adjust the control range using DEADBAND. Deadband range: 50–500 PPM (each press changes by 50 PPM)Example from manual:If Setpoint = 1000 PPM and Deadband = 200 PPM, output starts below 800 PPM.
