f. CO

Inject Light
The CO
2
inject light is activated whenever there is a demand for CO
2
to meet setpoint
requirements. Since the CO
2
inject light is independent of the CO
2
alarm, it will continue
to signal a need for CO
2
when the CO
2
alarm is set to either the defeat or silence
position.
g. CO
2
Zero Adjustment
The CO
2
zero adjustment is used for zeroing the CO
2
controller to specific control
conditions. It is the only user calibration adjustment on the CO
2
module. All internal
adjustments are for qualified service personnel only.
