42Override — The Override parameter is used to configure thenumber of hours and minutes the override will be in effect. Theuser initiates override by pressing the override button on thespace temperature sensor. This will cause the schedule to enterinto the Occupied mode. If global scheduling is used, all zonesusing the global schedule will enter Occupied mode. Pushingthe override button during Occupied mode will have no effect.If the occupancy override is due to end after the start of thenext occupancy period, the mode will transition from occupan-cy override to occupied without becoming unoccupied, and theoccupancy override timer will be reset.NOTE: If using the tenant billing function, the overridehours set point must be configured between 1 and 3 hours.Override: Units Hours: MinutesRange 00:00 to 24:00Default Value 00:00Broadcast Acknowledger — This configuration defines if thezone controller will be used to acknowledge broadcast messag-es on the CCN bus. One broadcast acknowledger is requiredper bus, including secondary busses created by the use of abridge.BroadcastAcknowledger: Range No/YesDefault Value NoSet Point Group Number — The Set Point Group Number isused to define the current zone controller as a part of a group ofzone controllers which share the same set points. All zone con-trollers with the same Set Point Group Number will have thesame set points. The set points are broadcast to the group by thezone controller defined by the Global Set Point Master config-uration. A value of 0 is a local schedule. Values 1 to 16 are usedfor global scheduling.Set PointGroup Number: Range 0 to 16Default Value 0Global Set Point Master — This configuration defines if thecurrent zone controller will broadcast its set point values to theother zone controllers which are made part of the same groupby configuring the Set Point Group Number.Global Set PointMaster: Range No/YesDefault Value NoMaximum Offset Adjustment — This configuration deter-mines the maximum amount that the set point will be biased(up or down), by adjusting the slide bar on the space tempera-ture sensor (if installed).Maximum OffsetAdjustment: Units delta F (delta C)Range 0 to 15Default Value 2Control Options — The Control Options configuration deter-mines whether the zone controller will use a humidity sensor oran indoor air quality sensor. A configuration of 0 means nosensors are used. A configuration of 1 means a Humidity Sen-sor is used. A configuration of 2 means an IAQ Sensor is used.Control Options: Range 0 to 2Default Value 0Humidity Control — These configuration values define thecalculation parameters for determining the airflow needed tocorrect a high humidity problem in the space. The MaximumOutput Value is measured in percentage of nominal terminalcfm.ProportionalGain: Range 0.0 to 9.9Default Value 1.5Integral Gain: Range 0.00 to 9.99Default Value 0.30Maximum OutputValue: Range 0.0 to 100.0% (max coolcfm)Default Value 100.0Indoor Air Quality Control — These configuration values de-fine the calculation parameters for determining the airflowneeded to correct a high incidence of air pollution contami-nants in the space, such as CO2. The Maximum Output Value ismeasured in percentage of nominal terminal cfm.Proportional Gain:Range 0.00 to 9.99Default Value 0.10Integral Gain: Range 0.00 to 9.99Default Value 0.03Maximum OutputValue: Range 0.0 to 100.0% (max coolcfm)Default Value 100.0IAQ Sensor Low Voltage — This configuration defines thelowest voltage which should be read from the air qualitysensor.IAQ SensorLow Voltage: Range 00.0 to 10.0Default Value 0.0IAQ Sensor High Voltage — This configuration defines thehighest voltage which should be read from the air quality sen-sor.IAQ SensorHigh Voltage: Range 00.0 to 10.0Default Value 10.0IAQ Low Reference — This configuration defines the valuein parts per million which correlate to the low voltage readingfrom the air quality sensor.IAQ LowReference: Units ppm (parts per million)Range 0 to 5000Default Value 0IAQ High Reference — This configuration defines the valuein parts per million which correlate to the high voltage readingfrom the air quality sensor.IAQ HighReference: Units ppm (parts per million)Range 0 to 5000Default Value 2000SECONDARY DAMPER SERVICE CONFIGURATIONSCREEN — The Secondary Damper Service Configurationscreen is used to configure the secondary damper settings. SeeTable 12.Zone Pressure Control — The Zone Pressure Control config-uration determines whether the primary and secondary control-lers will be configured for zone pressure control.Zone PressureControl: Range Dsable/EnableDefault Value DsableDual Duct Type — The Dual Duct Type setting configures thesecondary controller for the correct dual duct type. A value of 0configures the type to None. A value of 1 configures the type toSecond Inlet (Hot Deck). A value of 2 configures the duct toTotal Probe (terminal outlet).Dual Duct Type: Range 0 to 2Default Value 0800→
