CO2
1. CO2 System Enable ( Enabled/ disabled)
(Settings Screen)
This function will enable or disable the CO2 system. If the system is Enabled it will be displayed in the
MAIN screen. If it is disabled it will not be displayed.
In the Option/Settings screen for the CO2 system:
System Enabled (with check mark) means the System is enabled
System Enabled (without check mark) indicates that the system is disabled
2. CO2 Max Above Set point
This value determines the maximum deviation, measured in (%) that the chamber is permitted to rise above
set point, once it is reached before an alarm condition is declared.
3. CO
2
Time Out
This value determines the time, in minutes, for the CO
2
percentage to achieve set point. If the CO
2
percentage doesn't get to within its lower limit of set point within this time period an alarm condition is
declared
4. CO2 Min Below Set Point
This value determines the amount in % below the CO2 set point that the Time out timer will start.
5. CO
2
Inject Delay Time
This value specifies the time, in seconds, for an injection of CO
2
to be measurable at the sensor.
When CO
2
is injected into the chamber, the system delays until this time period has elapsed before making
a new control decision.
In this manner, diffusion induced delays do not cause the CO
2
system to overshoot the control set point.
General Options
1. Door close Delay Time
This value determines the time, in seconds, to turn on the door heater to a 50 percent duty cycle after an
inner glass door opening. Also inhibits CO
2
control for the same period.
2. Air Inject Time
This value specifies the time, in seconds, for an injection of air into the chamber
3. Air Inject Cycle Time
This value specifies the amount of time in minutes between each injection of air into the chamber
4. Digital Output Interval
This parameter specifies the frequency, in minutes that lines are to be printed on a status report.
If the frequency is specified as zero, no report will be printed.
5. Door Ajar Alarm Delay
Determines how long in minutes the glass door can be open before an alarm is declared.
6. Settings (top of screen)
Pressing the Settings text gives access to Settings screen containing the following:
•
The Filter Maintenance button to access:
•
Resetting the change filter notice

8.11 Resetting the Electronics Software
8.11.1 Factory Reset
The Factory Reset is similar to the Master Reset. However, it only changes the Options (returned to default
settings) and the environmental set-points (returned to their defaults).
To perform a Factory Reset, you will need to do the following:
NuAire Logo → Service Settings → 9876 Enter → Reset → Factory Reset → Confirm
The Incubator will perform the Factory Reset and return to the Main screen.
