ONLY monitor CO2 concentrations in up to (2) grow zones. • Please Note: the RAD-0502 may NOT be used for CO2 safety per OSHA guidelines as it does not meet the need to measure and operate at OSHA's Short Term Exposure Limit of 30,000 ppm.
Installation 1. Choose a suitable location at plant level to install the CO2 Sensor unit. 2. Choose a suitable location at eye level to mount the CO2 Grow Controller unit. 3. Next, connect a CO2 generator or bottled CO2 control regulator to the desired relays (please note the CO2 Grow Controller has 2 relay outputs.
Operation Startup Detection 1. Start up to read the status of sensor unit, the green font of sensor displays "fine" normally, and the red font displays "open" abnormally If you want to manually ignore the wrong sensor, long press the mode key for 3 seconds to exit the prompt interface and enter the main screen Switch Unit1 and Unit2 1.
