Complete CO2 Control Kit

CARBON-B1 CO2 Controller

The best option for assembling a CO2 system in terms of quality and price on the market. All you need is a suitable CO2 cylinder; connect the controller, set the desired parameters, and you will have perfect control over the carbon dioxide levels in your grow room. Guaranteed to increase your yields by 10–20%! 

CARBON-B1 is a carbon dioxide (CO2) controller. It maintains set CO2 levels by switching on a device that emits CO2. The user can set the desired CO2 level and the permissible deviation interval (hysteresis) using two rotary knobs. The controller switches off during the dark period using a built-in photocell. Three indicator lights (yellow, green and red) show the controller’s current status and the CO2 level with 50 ppm accuracy.

Installation method:

Plug CARBON-B1 into a standard 220V socket. For permanent mounting, use the mounting lug at the top of the housing. The CO2 sensor is on a cable, so it can be mounted on the wall in a suitable location.

Connect the device or devices whose operation will be controlled. Do not exceed the maximum current (10 A, or approximately 2200W). To control device(s) with higher power, use a relay.

Reading CO2 levels:

Once the device is plugged in and warmed up (about 5 min.), the red (x1k) and yellow (x100) indicator lights start flashing. The number of flashes of the red light indicates thousands of PPM (parts per million), while the number of flashes of the red light indicates hundreds of PPM. Thus, one flash of the red light and three flashes of the yellow light indicate a CO2 level between 1300 and 1400 PPM.

The green indicator light at the top right is lit when the photocell is activated, while the green indicator light in the centre turns on when the controller supplies power.

Setting up the controller:

Use the left button to select the desired CO2 level. This is the minimum CO2 level that will be maintained. When the CO2 content in the air falls below this level, the controller will supply power. Suitable levels for greenhouses are 1100-1600 PPM.

Use the right button to set the controller interval (hysteresis). This is the interval (in PPM) by which the CO2 content must increase before the controller switches off. Normal values are 50-150 PPM. A smaller interval means more frequent switching on and off.

Sensor calibration:

To calibrate the CO2 sensor, take the controller outdoors and leave it switched on for 10 minutes. Then turn the left knob fully counter-clockwise and the right knob fully clockwise. After 3 seconds, the controller will enter calibration mode and the red light will illuminate. MOVE AWAY FROM THE CONTROLLER!

When calibration is complete (3-6 min.), the yellow indicator light will turn on. If it flashes, an error occurred during calibration; start it again. Switch off the controller and return the buttons to their normal settings before switching it on again.
