HOW TO CALIBRATE CO
1. Place the controller outdoors in a shaded area. Do not place in direct sunlight. Keep away from
people, animals and other CO
2. Note: If calibration will be in a high traffic (vehicles) area or a highly populated area a slightly
increased calibration to around 400-475 PPM is recommended.
3. Plug in the controller and allow to "warm up" for a minimum of 30 minutes. For best results, allow
to "warm up" for an hour or longer.
4. Press Calibrate CO
be displayed. Press the up or down button to change the calibration setting. DO NOT exhale or
breathe on the unit while activating the calibration function.
5. Press ENTER/RESET to start the calibration sequence, (Co2_CAL) will be displayed and CO
calibration LED will be blinking. Leave controller alone for about 10 minutes.
6. When calibration is complete the display window will return to normal display and functions.
Place the sensor back into the grow area. All other functions remain as they were prior to
calibration.
SULFUR VAPORIZER WARNING!
If a sulfur vaporizer is used, first remove the remote sensor from the affected area or turn the
controller OFF and cover the remote sensor probe with a protective plastic bag. Remove the bag
before turning the power back ON.
NOTE: Failure to protect the sensor during sulfur use will result in damage to the infrared CO
sensor and void warranty.
