Specifications
Input Voltage: 120V
Maximum Amperage: 14.5A @ 120V
CO
2
Sensor Type: NDIR (Nondispersive Infrared)
CO
2
Accuracy: ± 60 ppm
Dimensions: 3” x 6” x 3.5”
Installation
• Plug the Controller into a NEMA 5-15 wall outlet with
a 120V power supply. Mount the remote sensor to the wall
at plant height and plug the cable into the unit. To install the
Controller permanently, secure the mounting tab at the
top of the unit to the wall.
• Plug the CO
2
-generating device to be controlled by the
Controller into the receptacle on the front of the Controller.
Ensure the device being connected to the Controller has the
proper voltage and will not exceed the maximum amperage
rating of the Controller.
Do not expose the Controller to water.
Reading CO
2
Levels
Allow the unit to warm up for about 5 minutes. When the unit is
ready, the red “x1k” and yellow “x100” LEDs will flash. The red
LED flashes once for each 1,000 ppm of CO
2
in the air and the
yellow LED flashes once for each 100 ppm. Example: If the red
LED flashes once and the yellow LED flashes three times, the
CO
2
ppm reading is 1240 - 1360 ppm.
Adjusting CO
2
Levels
Setpoint:
Select the desired CO
2
level using the knob labeled
“Setpoint ppm.” When the CO
2
level drops below the CO
2
set-point, the unit will turn on the CO
2
device. Recommended
setting is 1,100-1,600 ppm.
Deadband:
Adjust the deadband set-point using the knob labeled
“Deadband.” The deadband is the amount over the CO
2
set-point
the CO
2
must rise before the unit will turn off the CO
2
device.
Recommended setting is 50-150 ppm.
Calibrating the CO
2
Sensor
To calibrate the sensor, operate the unit and sensor normally
outside for about 10 minutes. Then turn the “Setpoint” knob fully
counterclockwise and the “Deadband” knob fully clockwise. After
3 seconds, the Controller will enter calibration mode and the red
LED will illuminate. Stand away from the unit during calibration.
After 3-6 minutes, the yellow LED will illuminate, indicating cali-
bration is complete. Disconnect the unit from power, and adjust
to desired settings before reconnecting the Controller.
FAQ
• How do I know if the photocell is working correctly?
The LED labeled “Daytime” on the top right edge of the unit
will illuminate when the photocell is in Day mode. The photocell
changes status on a 30-second delay.
Troubleshooting
• The Controller seems to be measuring CO
2
levels inaccurately.
Ensure proper air circulation around the CO2 sensor. To verify
the sensor’s accuracy, isolate the unit and sensor outside for
10 minutes. The unit should read 300-400 ppm. If the unit
gives a different reading, recalibrate the unit and sensor.
• The yellow LED flashes after calibration.
The calibration procedure did not work. Restart the
calibration procedure.
• The red and yellow LEDs remain on.
The CO
2
sensor is malfunctioning.
• The red and yellow LEDs blink continuously.
The unit has experienced power overload and has shut down.
Reduce the amperage load and reset the unit by unplugging it
for five seconds.
• The connected device is not being powered.
Ensure the device to be controlled is working correctly by
plugging the device into a reliable power source. Verify the
Controller is being supplied the correct voltage.
