IAQ Analog Sensor Config (Configuration
IQ.A.C)
This is used to configure the type of IAQ position control. It has
the following options:
•
IQ.A.C = 0 (No analog input). If there is no other minimum
position control, the economizer minimum position is Con-
figuration
IAQ
EC.MN and there will be no IAQ control.
•
IQ.A.C = 1 (IAQ analog input). An indoor air (space or return
air) CO
sensor is installed. If an outdoor air CO

also installed, or OAQ is broadcast on the CCN, or if a default
OAQ value is used, then the unit can perform IAQ control.
•
IQ.A.C = 2 (IAQ analog input with minimum position
override) — If the differential between IAQ and OAQ is
above Configuration
omizer minimum position will be the IAQ override posi-
tion (Configuration
IAQ
•
IQ.A.C = 3 (4 to 20 mA minimum position) — With a 4 to
20 mA signal connected to TB201 terminal 7 and 8, the
economizer minimum position will be scaled linearly from
0% (4 mA) to EC.MN (20 mA).
•
IQ.A.C = 4 (10K potentiometer minimum position) — With a
10K linear potentiometer connected to TB201 terminal 7 and
8, the economizer minimum position will be scaled linearly
from 0% (0 ohms) to EC.MN (10,000 ohms).
IAQ Analog Fan Config (Configuration
IQ.A.F)
This configuration is used to configure the control of the indoor
fan. If this option is used, then the IAQ sensor must be in the space
and not in the return duct.

It has the following configurations:
•
IQ.A.F = 0 (No Fan Start) — IAQ demand will never
override normal indoor fan operation during occupied or
unoccupied period and turn it on.
•
IQ.A.F = 1 (Fan On If Occupied) — IAQ demand will
override normal indoor fan operation and turn it on (if off)
only during the occupied period (CV operation with auto-
matic fan).
•
IQ.A.F = 2 (Fan On Occupied/Unoccupied) — IAQ demand
will always override normal indoor fan operation and turn it
on (if off) during both the occupied and unoccupied period.
For IQ.A.F = 1 or 2, the fan will be turned on as described
above when DAQ is above the DAQ Fan On Set Point (Con-

IAQ Discrete Input Config (Configuration
IQ.I.C)
This configuration is used to set the type of IAQ sensor. The fol-
lowing are the options:
•
IQ.I.C = 0 (No Discrete Input) — No discrete input will be
used and the standard IAQ sensor input will be used.
•
IQ.I.C = 1 (IAQ Discrete Input) — 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) — The IAQ level (high or low) will be indicated by
the discrete input and the economizer minimum position will
be the IAQ override position, IQ.O.P (when high). It is also
