Functional description 

This part describes the function of the configuration of 

CF8-D/W-IN

. Please note that the two outputs 

may completely or partly have other functions. These functions may be reprogrammed after the 
installation. To be sure that every unit is correctly programmed, in accordance to the actual 
application, a check by a PC and the standard UIP software (version 4.0 or higher) is necessary. 

OUT1 and OUT2 are used for the measuring signal of carbon dioxide concentration. 

OUT1 = measuring signal of carbon dioxide concentration 
OUT2 = measuring signal of carbon dioxide concentration
