Auto speed fan mode is also offered in heating mode applications; it will not however have any effect on 
dehumidification. It will be strictly for noise comfort issues 
 
Auto Speed Fan Mode operation for sequences 2 and 3 is dependent on Auto Fan parameter. When 

Auto Fan 

is set to:

 

 

AS ( Default ) = 

Auto Speed

 during occupied periods. Fan is always on during occupied periods. Low, 

medium and high speeds operate on temperature offset from setpoint. 

 

AS AD = 

Auto Speed

 

/ Auto Demand

 during occupied periods.  

- Medium and high speeds operate on temperature offset from setpoint. 
- Low speed operates on demand and will shut down when no demand is present
