Grow CO2 Enrichment Controller
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 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 selfdiagnostics program.
4. Now your product is tested and you can start the
installation.

!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 Enrichment 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 Enrichment Controller does not function if
disconnected from power mains.

Dimensions (LxWxD): 90x161x38 mm 3.5”x6.3”x1.5”
Ingress protection: IP 56
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

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.

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 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.
