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 fol-
lowing 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
automatic 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 unoccu-
pied 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 (Configuration

will be turned off when DAQ is below the DAQ Fan Off Set

trol can also be set up to respond to a discrete IAQ input.
The discrete input is connected to TB5-6 and 7.

IQ.I.C) — 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 Configuration

• 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, IQ.O.P (when high).
It is also necessary to configure how the fan operates when
using the IAQ discrete input.

IQ.I.F) — This is used to configure the operation of the
fan during an IAQ demand condition. It has the following
configurations:
• IQ.I.F = 0 (No Fan Start) — IAQ demand will never
override normal indoor fan operation during occupied or
unoccupied period and turn it on.
• IQ.I.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
automatic fan).
• IQ.I.F = 2 (Fan On Occupied/Unoccupied) — IAQ
demand will always override normal indoor fan opera-
tion and turn it on (if off) during both the occupied and
unoccupied period.

OQ.A.C) — This is used to configure the type of
outdoor sensor that will be used for OAQ levels. It has the fol-
lowing configuration options:
• OQ.A.C = 0 (No Sensor) — No sensor will be used and
the internal software reference setting will be used.
• OQ.A.C = 1 (OAQ Sensor with DAQ) — An outdoor
CO

sensor will be used.
• OQ.A.C = 2 (4 to 20 mA Sensor without DAQ).
