Please read this manual carefully and retain for future use. 

 

The Merlin CO2-X is designed to monitor carbon dioxide (CO

2

) in the air and temperature.  

The monitor has a digital traffic light style display indicating the carbon dioxide levels and temperature in 

the area. When CO

2

 gas or temperature reaches alarm state – this device is able to automatically drive 

ventilation fans reducing CO

2

 and/or temperature. 

 

 

The information contained within this manual should be referenced for typical installation and operation
