Usage Instructions

Before installation, test the set to verify proper function by following these steps:

1. Open the box and carefully take the components out of the package.

2. Find the power supply in the package and attach the correct mains-adaptor for your country’s outlet, then connect the power supply to the electrical outlet. The set should now activate.

3. Check that all LEDs on the Grow CO2 Enrichment Controller
   illuminate and that the built-in buzzers beep. This is part of the self- diagnostics program.

4. Now your product is tested and you can start the installation.

Mount the Grow CO2 Enrichment Controller at the same height as the foliage of the plants, where the photosynthesis is taking place. If plant lighting is used in the greenhouse, make sure that the plant light hits the Grow CO2 Enrichment Controller. An internal light sensor in the Grow CO2 Enrichment Controller makes it possible to activate the CO2-control only when the plant lighting is on. It is possible to disable this function via DIP-switch.

The system control the CO2 level with a plug and play Enrichment Valve. If the CO2 gas for the grow room is produced by burning gas, use the RCB external relay box to start and stop the burner, instead of the Enrichment Valve. Both the Enrichment Valve and the RCB have RJ45 connectors for direct connection to the Grow CO2 Enrichment Controller.

Just like the LogiCO2 Safety CO2 Sensor, the Grow CO2 Enrichment Controller can be adjusted for the correct altitude.

Function

The LogiCO2 Grow CO2 Enrichment Controller is a device that measures the concentration of CO2 in the ambient environment of the room being controlled and opens/closes our enrichment valve to achieve a perfectly enriched CO2 environment in the grow room.
Mount the Grow CO2 Enrichment Controller at the same height as the foliage of the plants, where the photosynthesis is taking place. If plant lighting is used in the greenhouse, make sure that the plant light hits the Grow CO2 Enrichment Controller. An internal light sensor in the Grow CO2 Enrichment Controller makes it possible to activate the CO2-control only when the plant lighting is on. It is possible to disable this function via DIP-switch.

The system control the CO2 level with a “plug and play” Enrichment Valve. If the CO2 gas for the grow room is produced by burning gas, use the RCB external relay box to start and stop the burner, instead of the Enrichment Valve. Both the Enrichment Valve and the RCB have RJ45 connectors for direct connection to the Grow CO2 Enrichment Controller.
Just like the LogiCO2 Safety CO2 Sensor, the Grow CO2 Enrichment Controller can be adjusted for the correct altitude.

Adaptive CO2-control
The Grow CO2 Enrichment Controller is default set to use a fixed dosing time of 30 or 60 seconds every 5 minutes. The Grow CO2 Enrichment Controller also has an Adaptive CO2-control algorithm that automatically adjust the dosing time of CO2 between 10 to 120 seconds. This dosage of CO2 is done in intervals of 5 minutes. The initial dosage time is 30 seconds. It is possible to enable the Adaptive CO2-control via DIP-switch on the printed circuit board.

The Grow CO2 Enrichment Controller has an adjustable CO2 setpoint via a push button on the outside of the cover. The setpoint for the target CO2 concentration is adjustable from 700 to 2000 ppm in steps of 50 ppm. The default setpoint is 1200 ppm. Setpoint “OFF” stops the CO2 regulation.
The hysteresis can be set to 40 or 100 ppm and default setting is 40 ppm.

The display is alternately reading:

• The current CO2 concentration
• The CO2 target setpoint value
• The current altitude setting (height over the ocean)

It can also show “Low” if the current concentration is 200 ppm below the setpoint, indicating for example that the CO2 container is empty. The green “Power on” LED starts blinking to indicate this function. If connected to a LogiCO2 Safety System Central Unit, the Central Unit will also show “/Low”, after the concentration value, on the display.

Optional Remote Connection box for fans
Use a RCB external relay box (0471) and connect it to the Grow CO2 Enrichment Controller, to activate greenhouse fans. The fans will be on when the Grow CO2 Enrichment Controller actively is controlling the CO2 concentration. If the light sensor in the Grow CO2 Enrichment Controller is enabled, the fans will be on if it is light and off when it is dark in the greenhouse. When it is dark, the Grow CO2 Enrichment Controller will also stop the CO2 enrichment.

Connected with CO2 Safety System
The Grow CO2 Enrichment Controller can be used in conjunction with the Mk9 CO2 Safety System to make the perfect combination of safety and efficiency.

When the Grow CO2 Enrichment Controller is connected to the Mk9 Central Unit the current CO2 concentration can also be read on the Central Unit’s display.

LED indications on the Grow CO2 Enrichment Controller

• Red: Alarm – CO2 concentration over 5000ppm.
• Green: Adding CO2 gas
• Green: Power on

If the display is showing “AbC0” at startup, the automatic CO2 calibration is disabled.
The LogiCO2 Safety System Central Unit display shows the ID number of the CO2 Sensor, its current CO2 concentration followed by:

• Low: Concentration 200 ppm below the setpoint
• On: CO2-control activated
• Off: Only when light sensor is activated and it is dark

Explanations of symbols

• Direct current
• Double insulation

Accessories

• Item code / Description
• 0475 Enrichment valve with filter
• 0471 RCB box, fan control

Installation

Mount the Grow CO2 Enrichment Controller at the same height as the foliage of the plants, where the photosynthesis is taking place. If plant lighting is used in the greenhouse, make sure the plant light hits the Grow CO2 Enrichment Controller. Avoid direct water spraying on the Grow CO2 Enrichment Controller.

The different units are connected to each other by cables. The blue marked cable is used for the Enrichment Valve and/or for the RCB external relay box, for activation of fans. The RCB external relay box can also be used to start and stop burner for production of CO2 gas.
The red marked cable are for communication and power. Please observe, all cables have splitters at the end to facilitate extended cable lengths. When installing, the cables may need to be disconnected for purposes of cable routing. When reconnecting, please make sure that you connect to the original splitters and connectors. If possible, route the cables through cable conduits between the units, for a neat and safe installation.

Protective collar seals and cable ties are included. They must be used as below to protect the RJ45 1-1 connector or RJ45 1-2 splitter from moisture and dust.

Connecting to the power supply
A separate power supply (100-240 VAC) supplies power to the system. Please observe that you have to connect the appropriate plug adaptor to the power supply depending on which country you are in. Connect the power supply to the electrical outlet. Mount the included plug-lock so that the power supply can not be disconnected without the use of tools.
It is also possible to order a hardwired power supply option when and were it is needed.
