Digital CO2 PPM Controller (BETA-8)

BETA-8 Cut Sheet


Features
Automatically control CO2 level during the Day mode Built-in photocell detecting day&night status
LED screen dispiay,easy operation
120V output for CO2 Regulator or Generator


Overview
The BETA-8 CO2 controller oers a precision CO2 NDIR sensor / controller in an
aordable easy-to-use package. The BETA-8 features a high-quality remote CO2 sensor (with 16ft cable) and built-in photocell to automatically activate your supple- mental CO2 system to maintain CO2 PPM levels only during daylight hours. The BETA-8 also has adjustable deadband and min-max recall. It also has a ‘fuzzy-logic’ feature which will more accurately control compressed CO2 systems.The CO2 sensor can be easily re-calibrated and will continue to operate accurately for many years.

User Manual

 

OVERVIEW

Thank you for purchasing our BETA-8 CO2 Controller, which is a simple and affordable way to control your CO2 injection device. Choose your desired CO2 level and the Controller will maintain that specified value. A built-in photocell on the sensor will deactivate CO2 injection at night. A remote sensor with 16ft long cable allows close placement to plant canopy.

Night Mode: the Controller will turn off the output of CO2 device.

Day Mode:

a) lf the Fuzzy Logic function is disabled, the unit will OPEN the output of the CO2 device when the current CO2 level is below setpoint, and CLOSE the output when the current CO2 level is above the CO2 setpoint plus deadband value.

b) lf the FuzzyLogic function is enabled, the unit will fully OPEN the output of CO2 device when the current CO2 level is much lower than the setpoint. When the CO2 level is close to the setpoint, the unit will calculate and send PWM signal to control the output of CO2 device, The PWM cycle is 5 seconds.

 

INSTALLATION

  • Mount the Controller on wall, place the sensor in a well ventilated area.
  • Connect the CO2 sensor to the Controller.
  • Plug the Controller into a 120V NEMA 5-15 wall outlet.
  • Program the desired setting before connecting to CO2 generator or regulator.
  • Plug a CO2 device into the power outlet of the unit. Ensure that the CO2 device has a proper voltage (120 V) and is not exceeding its max amperage rating.

OPERATION INSTRUCTIONS 

1.  Reading CO2 Level

  • Warm up the unit for approximately 1 minute.
  • After warm-up, the LED will display the current CO2 level (as PPM).
  • The CO2 Device LED will turn green when connected with CO2 generator or CO2 regulator.

 

 

 

 

 

2. Maximum CO2 Recorded Value Recall

Press HOME button one time, the LED will display the maximum CO2 recorded value and the Max LED indicator will be blinking. To clear the record, press UP button or DOWN button , all digits on LED display will be blinking, press and hold HOME button for 3 second to clear the record.

 

 

 

 

 

3. Minimum CO2 Recorded Value Recall

Press HOME button twice, the LED will display the minimum CO2 recorded valueand and the Min LED indicator will be blinking. To clear the record, press UP button or DOWN button, all digits on LED will be blinking, press and hold HOME button for 3 second to clear the record.

 

 

 

 

4. CO2 PPM Level Setpoint Adjustment

The factory setpoint of the CO2 PPM level is 1200 PPM. lf the CO2 level is lower than 1200 PPM, the controller will turn on output relay to drive the CO2 device to enrich the CO2 in the grow area. When the CO2 PPM level exceeds setpoint plus deadband (50PPM), the controller wil cut off the output. To adjust the setpoint, press HOME button 3 times, the Setpoint LED indicator will be blinking, the LED will display the current setpoint. Press UP or DOWN, all digits on the LED will be blinking and then press UP or DOWN button to increase or decrease the setpoint.

 

 

 

 

 

5. CO2 PPM Deadband Adjustment

Factory deadband setting is 50 PPM. To adjust the deadband, press HOME 4 times, the Deadband LED will be blinking and the LED will display the current deadband setting. Press UP or DOWN the digits on the LED will be blinking and then press UP or DOWN to increase or decrease the deadband.

 

 

 

 

6. Fuzzy Logic Mode

  • Fuzzy Logic mode counters rising or falling CO2 levels by quickly activating the CO2 solenoid valve, allowing CO2 levels to be controlled more precisely.
  • The Fuzzy Logic function is active if the Fuzzy Logic LED indicator illuminates.
  • Factory default setting of fuzzy logic is off.

To activate the fuzzy logic, press HOME button 5 times, the Fuzzy Logic LED indicator will be blinking. Press UP or DOWN, the LED displays OFF. Press UP or DOWN, the LED displays ON. Press HOME button to confirm and activate the fuzzy logic and the Fuzzy Logic LED indicator will illuminate.

  • This function can be used ONLY with compressed CO2.
  • Do not use Fuzzy Logic with a CO2 generator!!!

 

 

 

 

7. Calibrating the CO2 Sensor

  • Place the sensor outdoors in a shaded area. Do not place in direct sunlight. Keep away from people, animals and other CO2 emitting units.

    Note: lf calibration will be in a high-traffic area or highly populated area, a slightly higher calibration value of 400-475 ppm is recommended.
  • Plug in the Controller and allow it to warm up for a minimum of 30 minutes but 1 hour is recommended.
  • Press HOME button 6 times to activate the automatic calibration, the [Calibrate] LED indicator will be blinking. Press UP or DOWN, the CO2 level (400 ppm) will be displayed on the LED and blinking. Press UP or DOWN to adjut the calibration level if you have an accurate reference. Otherwise, the recommended level will be 400 ppm. Press and hold HOME button 3 seconds to activate the calibration.
    Note: DO NOT exhale or breathe near the sensor while activating the calibration function.
  • The LED will display the countdown timing.
  • When it is complete, the screen will display functions normally. Calibration will not affect any other settings.
    Note: lt may take up to 90 seconds to complete the calibration process.

 

 

 

 

8. Restore the Factory Settings

Press and hold HOME button before plugging controller into wall outlet. Power the controller, the LED will display "rESt" and blink. Keep holding the HOME button for 5 seconds until the LED displays "donE".
