Table 67 — Indoor Air Quality Configuration
IAQ Discrete Fan Config (Configuration
IAQ
AQ.CF
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 over-
ride normal indoor fan operation during occupied or unoc-
cupied 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 auto-
matic fan).
• IQ.I.F = 2 (Fan On Occupied/Unoccupied) — IAQ de-
mand will always override normal indoor fan operation
and turn it on (if off) during both the occupied and unoccu-
pied period.
Economizer Min Position (Configuration
IAQ
DCV.C
EC.MN)
This is the fully occupied minimum economizer position.
IAQ Demand Vent Min Pos. (Configuration
IAQ
DCV.C
IAQ.M)
This configuration will be used to set the minimum damper po-
sition in the occupied period when there is no IAQ demand.
IAQ Econo Override Pos (Configuration
IAQ
AQ.SP
IQ.O.P)
This configuration is the position that the economizer goes to
when override is in effect.
OAQ Lockout Value (Configuration
IAQ
AQ.SP
OAQ.L)
This is the maximum OAQ level above which demand ventila-
tion will be disabled.
Diff. Air Quality Lo Limit (Configuration
IAQ
AQ.SP
DAQ.L)
This is the differential CO
2
level at which IAQ control of the
dampers will be initiated.
Diff. Air Quality Hi Limit (Configuration
IAQ
AQ.SP
DAQ.H)
This is the differential CO
2
level at which IAQ control of the
dampers will be at maximum and the dampers will be at the
Configuration
IAQ
DCV.C
EC.MN.
DAQ ppm Fan On Set Point (Configuration
IAQ
AQ.SP
D.F.ON)
This is the CO
2
level at which the indoor fan will be turned on.
DAQ ppm Fan Off Set Point (Configuration
IAQ
AQ.SP
D.F.OF)
This is the CO
2
level at which the indoor fan will be turned off.
IAQ Low Reference (Configuration
IAQ
AQ.S.R
IQ.R.L)
This is the reference that will be used with a to non-Carrier
IAQ sensor that may have a different characteristic curve. It
represents the CO
2
level at 4 mA.
IAQ High Reference (Configuration
IAQ
AQ.SR
IQ.R.H)
This is the reference that will be used with a non-Carrier IAQ
sensor that may have a different characteristic curve. It rep-
resents the CO
2
level at 4 mA.
OAQ Low Reference (Configuration
IAQ
AQ.S.R
OQ.R.L)
This is the reference that will be used with a non-Carrier OAQ
sensor that may have a different characteristic curve. It rep-
resents the CO
2
level at 4 mA.
