/ = Calculated Airflow is 800 CFM.
Airflow display is rounded down to the nearest 10 cfm
NOTES:
(1) The menu status displayed is solely dependent on the input of 24VAC
that is applied to the low voltage terminal strip.
(2) The status will alternate between the system mode and the airflow
request every 2 seconds.
(3) If an error occurs, an E*.* will alternately flash with the system mode
and airflow request. See first example
(4)
Mul!ply the value shown by 10 for actual airflow
