5.13.1 CO
2
Alarm
The CO
2
Alarm is triggered when the set CO
2
level cannot be reached within 25 minutes. It
consists of an audible alarm and a visual signal (CO
2
knob blinks red). In addition, when this
alarm is triggered the CO
2
supply to the CERO will be interrupted.
It is not possible to deactivate this setting, for safety reasons. However, acknowledging the
alarm status will interrupt the audible alarm.
ATTENTION
After acknowledging the CO
2
alarm:
Verify that the CERO is tightly sealed (e.g. front cover in place, convection
channel functional).
Verify the integrity of the CO
2
supply.
5.13.2 Tolerance of the Out of Range Notification (CO
2
and Temperature)
The CERO notifies out of range environmental conditions (temperature and CO
2
level) as
follows:
- a general audible notification is triggered
- the CO
2
/ Temperature Button blinks red
NOTE
The CO
2
range is defined as:
CO
2
range = Set CO
2
level ± CO
2
tolerance
The temperature range is defined as:
Temperature Range = Set temperature ± temperature tolerance
You may adjust the tolerance of the temperature and CO
2
notification:
1. In the System Menu, go to Settings.
2. In the window Tolerance, adjust the temperature and CO
2
level tolerance.
You may also disable the audible notification:
1. In the System Menu, go to Settings.
2. In the window Audible Notification, deselect “General notification” by clicking on it.
