Highest 

The affected Exhaust Fans and Auxiliary Airflows either run at the calculated fan speed or 
the percent speed governed by this analog input, whichever is highest. 

 
Add 

The analog input percentage is added to the calculated fan speed for the Exhaust Fans and 
Auxiliary Airflows. 

 
Average 

The fan speed for the Exhaust Fans and Auxiliary Airflows is first calculated and then is 
averaged with the analog input value. 

 
Aux. Highest 

The affected Auxiliary Airflows either run at the calculated fan speed or the percent speed 
governed by this analog input, whichever is highest.  Exhaust Fans are not affected. 

 
Aux. Add 

The analog input percentage is added to the calculated fan speed for the Auxiliary 
Airflows.  Exhaust Fans are not affected. 

 
Aux. Average 

The fan speed for the Auxiliary Airflows is first calculated and then is averaged with the 
analog input value.  Exhaust Fans are not affected. 
 

Analog Output Status 

There is one physical analog output on the Intelli-Hood System Controller.  The analog 
output can be configured in either 0-10VDC or 0-20mA operation and can be associated 
with any Auxiliary Airflows in the system.  The Analog Output Status reports the current 
value of the system’s physical analog output as a percentage.
