Running AFMS Learning Mode  

Before Starting Learning Mode  

For valid results, first ensure that:  

l

The parameters are set correctly. (See Setting AFMS Parameters on page 5.)  

l

The sensors are calibrated. (See Calibrating the AFMS's Sensors on page 7.)  

l

The supply air fan is running at a normal, steady rate (without hunting or sporadic spikes).  

l

If the unit has a heat recovery wheel, it is turned off.  

l

If any heating or cooling sources are located upstream of the MAT sensor, they are turned off.  

l

If the unit has a bypass damper, it is set to 100% open.

Select the Learn tab.  

1.  

Take note whether Learn Ready reports READY or NOT READY.  

2.  

Interpreting Learn Ready Status  

If READY is reported, you may manually start Learning Mode. (Continue to Manually Starting Learning Mode
