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
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
