IAQ Discrete Input Config (
Configuration

) — This configuration is used to set the type of IAQ
sensor. The following are the options:
•
IQ.I.C
= 0 (No Discrete Input) — This is used to indicate
that no discrete input will be used and the standard IAQ
sensor input will be used.
•
IQ.I.C
= 1 (IAQ Discrete Input) — This will indicate
that the IAQ level (high or low) will be indicated by
the discrete input. When the IAQ level is low, the
economizer minimum position will be

.
•
IQ.I.C
= 2 (IAQ Discrete Input with Minimum Position
Override) — This will indicate that the IAQ level (high
or low) will be indicated by the discrete input and the
economizer minimum position will be the IAQ override
position,

(when high).
