Default/Range
IAQ/Ventilation Alarm
Occupied High CO2 Alarm Limit
– The value that the CO
2
sensor must exceed to
generate an
Indoor Air Quality Alarm
in the occupied mode if
DCV Control
is set to
Enable
. There is a fixed hysteresis of 100ppm for return to normal.

R:
1100ppm
0 to 9999 ppm
Alarm Delay (min/ppm)
– The fractional portion of a minute used to determine the
amount of delay before an indoor air quality alarm is generated when the controller
transitions to the occupied mode. The delay time equals this value multiplied by the
difference between the sensor CO
2
value and the setpoint plus 15 minutes.
D:
R:
0.25 minutes
0.10 to 1.00 minutes
