Economizer Fault Detection and
Diagnostics
Fault detection of the outdoor air damper will be
evaluated based on the commanded position of the
damper compared to the feedback position of the
damper. The damper is commanded to a position
based on a 2-10 Vdc signal.
N No otte e:: In table below, ‘not economizing when should’
and ‘economizing when should not be’ have
been determined.
