REMOTE SENSOR CALIBRATION
STEP
>>>>>IMPORTANT<<<<<
Expose your sensors to outdoor air for a minimum of 1-2 minutes, fresh air being used
as a reference. If the value on screen is around 350 to 450 PPM, YOU DO NOT NEED
TO RECALIBRATE YOUR UNIT.
1
Turn knob to select the first zone sensor you would like to calibrate ( Zone #1 or Zone
#2 indicator will be ON accordingly).
2
Click knob repeatedly until “Calibration” indicator turn ON, then controller screen
shows « CO2 ».
3
Press knob and keep it pressed for about 5 seconds, until « CAL » appears on screen.
4
Let button go, « CO2 » and « CAL » appear on screen alternately (blinking).
5
Click knob again, then « CAL » and « 400 » appear on screen alternately (blinking).
IMPORTANT : if the value shown IS NOT 400, turn the knob to set value to 400.
6
TO CALIBRATE : press knob and keep it pressed for at least 5 seconds, until « CAL »
shows up on screen (not blinking), then let button go.
IMPORTANT : if you “click” the knob instead of “pressing and maintaining the
knob pressed”, you will exit WHITOUT calibrating.
7
The automatic calibration takes just seconds. When completed, « CAL » et « GOOD »
appear on screen alternately (blinking) for 5 seconds, then the controller returns to
normal operation.
IMPORTANT : you MUST see « GOOD » on screen at the end of the calibration
process. If not, the calibration has FAILED. Then go back to step 1.
8
Turn knob to select the second zone sensor you would like to calibrate (Zone #1 or
Zone #2 indicator will be ON accordingly) and then do again STEP 2 to STEP 7.
