SETTING UP THE SYSTEM — The IAQ configuration options are under the Local Display Mode ConfigurationIAQ. See Table 57. IAQ Analog Sensor Config (ConfigurationIAQ AQ.CFIQ.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 will be ConfigurationIAQEC.MN and there will be no IAQ control. • IQ.A.C = 1 (IAQ analog input). An indoor air (space or return air) CO 2 sensor is installed. If an outdoor air CO 2 sensor is 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 ConfigurationIAQAQ.SPDAQ.H, the economizer minimum position will be the IAQ override position (ConfigurationIAQAQ.SPIQ.O.P). • 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 kilo-ohms) to EC.MN (10 kilo-ohms). IAQ Analog Fan Config (ConfigurationIAQAQ.CF 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 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 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 (ConfigurationIAQAQ.SPD.F.ON). The fan will be turned off when DAQ is below the DAQ Fan Off Set Point (ConfigurationIAQAQ.SPD.F.OF). The control can also be set up to respond to a discrete IAQ input. The discrete input is connected to TB202 terminal 12 and 13. IAQ Discrete Input Config (ConfigurationIAQAQ.CF 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 IAQDCV.CIAQ.M. • 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.P.O (when high). It is also necessary to configure how the fan operates when using the IAQ discrete input. 76 ECONOMIZER MINIMUM DAMPER POSITION MINIMUM IAQ DAMPER POSITION INCREASING VENTILATION VENTILATION FOR PEOPLE VENTILATION FOR SOURCES 100 500 AQ DIFFERENTIAL LOW (DAQ.L) 700 1000 AQ DIFFERENTIAL HIGH (DAQ.H) Fig. 13 — IAQ Control INSIDE/OUTSIDE CO 2 DIFFERENTIAL INSIDE CO 2 CONCENTRATION NOTE: Calculating the IAQ.M and EC.MN damper position based on differential IAQ measurement. Based on the configuration parameter IAQREACT, the reaction to damper positioning based on differential air quality ppm can be adjusted. IAQREACT = 1 to 5 (more responsive) IAQREACT = 0 (linear) IAQREACT = –1 to –5 (less responsive) Fig. 14 — IAQ Response Curve IAQ Discrete Fan Config (ConfigurationIAQAQ.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 override normal indoor fan operation during occupied or unoccupied period and turn it on.

Economizer Min Position (ConfigurationIAQDCV.C EC.MN) — This is the fully occupied minimum economizer position. IAQ Demand Vent Min Pos. (ConfigurationIAQ DCV.CIAQ.M) — This configuration will be used to set the minimum damper position in the occupied period when there is no IAQ demand. IAQ Econo Override Pos (ConfigurationIAQAQ.SP IQ.O.P) — This configuration is the position that the economizer goes to when override is in effect. OAQ 4-20 mA Sensor Config (ConfigurationIAQ AQ.CFOQ.A.C) — This is used to configure the type of outdoor sensor that will be used for OAQ levels. It has the following 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 2 sensor will be used. • OQ.A.C = 2 (4 to 20 mA Sensor without DAQ). OAQ Lockout Value (ConfigurationIAQAQ.SP OAQ.L) — This is the maximum OAQ level above which demand ventilation will be disabled. Diff. Air Quality Lo Limit (ConfigurationIAQAQ.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 (ConfigurationIAQAQ.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 IAQDCV.CEC.MN. 77 DAQ ppm Fan On Set Point (Configuration IAQAQ.SPD.F.ON) — This is the CO 2 level at which the indoor fan will be turned on. DAQ ppm Fan Off Set Point (ConfigurationIAQ AQ.SPD.F.OF) — This is the CO 2 level at which the indoor fan will be turned off. IAQ Low Reference (ConfigurationIAQAQ.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 (ConfigurationIAQAQ.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 represents the CO 2 level at 4 mA. OAQ Low Reference (ConfigurationIAQAQ.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 represents the CO 2 level at 4 mA. OAQ High Reference (ConfigurationIAQAQ.S.R OQ.R.H) — This is the reference that will be used with a non- Carrier OAQ sensor that may have a different characteristic curve. It represents the CO 2 level at 4 mA. Diff. IAQ Responsiveness (ConfigurationIAQAQ.SP IAQ.R) — This is the configuration that is used to select the IAQ response curves as shown in Fig. 14. PRE-OCCUPANCY PURGE — The control has the option for a pre-occupancy purge to refresh the air in the space prior to occupancy. This feature is enabled by setting ConfigurationIAQ IAQ.PIQ.PG to Yes. The IAQ Purge will operate under the following conditions: • IQ.PG is enabled • the unit is in the unoccupied state • Current Time is valid • Next Occupied Time is valid • time is within two hours of the next occupied period • time is within the purge duration (Configuration IAQIAQ.PIQ.P.T)
