WARNING!
Please read these instructions carefully prior to start-up and use. These instructions should be saved for future reference and passed on to any subsequent owner. Failure to follow any of these instructions could result in bodily harm or death, and could void product warranties. LogiCO2 International AB, its affiliates and third party providers assume no responsibility for claims arising from improper or careless use or handling of its products. Retain this instruction.

LEGAL NOTICE
All persons responsible for the operation and maintenance of this equipment must read and understand the safety and operating information contained in this guide. Installation and service of this equipment should be performed only by professionals. The function of the equipment will be impaired if it is not properly installed. Disconnection from supply source: When installing the Grow CO2 Controller to the power net, please ensure that the fuse that the system runs on is clearly marked. This makes it easy to disconnect the power to the system, if needed. It is very important to be aware that the Grow CO2 Controller does not function if disconnected from power mains.

Testing set, BEFORE INSTALLATION

The different sets are delivered pre-connected in the package. Always test the set before installation to verify proper function!

1. Open the box and carefully take the componentsout 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 Controller illuminate and that the built-in buzzers beep. This is part of the selfdiagnostics program.
4. Now your product is tested and you can start the installation.

Function

• The LogiCO2 Grow CO2 Controller is a device that measures the concentration of CO2 in the ambient environment of the room being controlled and opens/closes a solenoid valve to achieve a perfect CO2 environment in the grow room.
• Mount the Grow CO2 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 Controller. An internal light sensor in the Grow CO2 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.
• Use the RCB external relay box (0471) connected to the Grow CO2 Controller, to activate greenhouse fans. The fans will be on when the Grow CO2 Controller actively is controlling the CO2 concentration. If the light sensor in the Grow CO2 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 Controller will also stop the CO2 dosage.
• The Grow CO2 Controller Add-on kit consists of a Grow CO2 Controller that can be connected to the Mk9 CO2 Safety System Base Set. The system can control the CO2 level with a “plug and play” Solenoid Valve Kit. 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 Solenoid Valve Kit. Both the Solenoid Valve Kit and the RCB have RJ45 connectors for direct connection to the  Grow CO2 Controller. Just like the LogiCO2 Safety CO2 Sensor, the Grow CO2 Controller can be adjusted for the correct altitude.
• The LogiCO2 Grow CO2 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 Controller is connected to the Mk9 Central Unit the current CO2 concentration can also be read on the Central Unit´s display.
• The Grow CO2 Controller 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 disable the Adaptive CO2-control via DIP-switch on the printed circuit board, and instead use a fixed dosing times of 30 or 60 seconds every 5 minutes.
• The Grow 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, this will also show “/Low” after the concentration value, on the display.

LED indications on the LogiCO2 Grow Controller

• 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

Installation

Mount the Grow 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 Controller. Avoid direct water spraying on the Grow Controller. The different units are connected to each other by cables. The blue marked cable is used for the Solenoid Valve Kit 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 lenghts. 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.
