On Maverick (MPS) and Rebel (DPS) units the OA ow station
needs to be wired to terminals X3 and M on expansion module
B. On Rooftop (RTU) and Self Contained (SCU) units, the
OA ow station needs to be wired to terminals X1 and M on
expansion module E. Terminal M is common for all analog
inputs. Make sure the polarity is correct on the eld wiring to
read a valid CFM value. See Table 13 on page 23
