47POSITION SINGLE ZONE — This variable displays whetherthe individual zone positioning process has been enabled. Ifthis decision is forced to Enable, the Linkage Coordinator zonecontroller will set all system zone dampers to their configuredCool Maximum Positions and display the values in Zone(1-32) Damper Position variables.At this time, if any of the Zone (1-32) Damper Positionvariables are forced, the zone will be repositioned to this newmaximum position. The forced position will be shown on theZone (1-32) Damper Position variable with a Supervisor force.This Supervisor force will disappear and the damper’s currentposition will display when the new damper position has beenbroadcasted to the zone controller's Damper Reference point.The Damper Reference point will display a Control forcewhich will remain until System Commissioning is disabled andthe Damper Position will go to the new desired position.NOTE: If this zone controller is not the Linkage Coordinator,enabling this variable will have no effect.PositionSingle Zone: Display Range Enable/DisableNetwork Access Read/WriteZONE (1-32) DAMPER POSITION — This variable displaysthe current damper position of all system zones during systemcommissioning. These values can be used to verify and changeconfigured maximum damper positions when All ZoneDampers to Max is Enabled and verify and change configuredminimum damper positions when All Zone Dampers to Minis Enabled. The user can also reposition individual zone’sdampers when Position Single Zone is Enabled. Force thisvalue to the desired minimum or maximum damper position.Zone (1-32)Damper Position: Display Range 0 to 100%Network Access Read/WriteBYPASS DAMPER POSITION — This variable displaysthe bypass damper position.BypassDamper Position: Display Range 0 to 100%Network Access NoBYPASS PRESSURE SENSOR — This variable displaysthe current value of the bypass static system pressure.BypassPressure Sensor: Display Range 0.00 to 2.00 in. wgNetwork Access NoBYPASS PRESSURE SET POINT — This variable displaysthe current Bypass Pressure set point. At any time in the systemcommissioning process, the user can force the Bypass Pressureset point. Typically the maximum unit rated duct velocity pres-sure would be entered in this decision prior to enabling All ZoneDampers to Maximum. When this value is forced, the new setpoint is written to the Pressure Set Point Table in the bypasscontroller over the communication network. The bypass con-troller then controls to the new bypass pressure set point.Bypass PressureSet Point: Display Range 0.00 to 2.00 in. wgNetwork Access Read/WriteZone Status Maintenance Table — The Zone StatusMaintenance Table (ZCOMAINT) displays the communica-tion status of the air source, the optional bypass controller, andeach of the zone controllers in the 3V™ control system. Thistable is only active in the Linkage Coordinator zone controller.See Table 20.AIR SOURCE STATUS — This variable displays the com-munication status of the air source.NOTE: If the zone controller is not a Linkage Coordinator, thestatus will be NONE.Air SourceStatus: Display Range Com OK, None, FailedBYPASS COMM STATUS — This variable displays thecommunication status of the bypass damper controller.NOTE: If the zone controller is not a Linkage Coordinator, thestatus will be NONE.Bypass ComStatus: Display Range Com OK, None, FailedZONE (1-32) COMM STATUS — This variable displays thecommunication status of each zone controller.NOTE: If the zone controller is not a Linkage Coordinator, thestatus will be NONE.Zone (1-32)Comm Status: Display Range Com OK, None, FailedZone Device Maintenance Table — The Zone DeviceMaintenance Table (ZDEVMAIN) displays the type of devicefound at each address in the 3V control system beginning with thedevice found at the address that is one element higher than theLinkage Coordinator zone controller, decrementing by 1 until theconfigured number of zones have been checked. This table is onlyactive in the Linkage Coordinator zone controller. See Table 21.BYPASS DEVICE TYPE — This variable displays the typeof device found at the location where there is typically a bypasscontroller. This location is one address higher than the LinkageCoordinator zone controller. Valid displays for this variable are:• None = No device present/com. fail/ pending• Master = Linkage Coordinator found (typically found atZD_DEV01 only)• Bypass = bypass controller• PDZone = pressure dependent zone• PIZone = pressure independent zone• Other = other Carrier Network device foundNOTE: If this zone controller is not a Linkage Coordinator, thevalue of this display will be None.ZONE (1-32) DEVICE TYPE — This variable displays thetype of device found when the master scans zones 1 through nwhere n is the number of zones (1-32) configured in theNumber of Zones decision in the Linkage Configuration Table.The zones are scanned in descending order, beginning with theLinkage Coordinator itself at zone n.Valid displays for this variable are:• None = No device present/com. fail/pending• Master = Linkage Coordinator found (typically found atZD_DEV01 only)• Bypass = bypass controller• PDZone = pressure dependent zone• PIZone = pressure independent zone• Other = other Carrier Network device foundNOTE: If this zone controller is not a Linkage Coordinator, thevalue of this display will be None.Zone Maintenance Table — The Zone MaintenanceTable (ZNMAINT) displays the status of the air source (heating,cooling, ventilation) and the reference values that the zone isusing for control. This table also displays whether this zone is theLinkage Coordinator, whether there is an override in effect, andwhether there are any loadshed conditions currently in effect.See Table 22.OCCUPIED — This variable displays the current occupiedmode for the zone controller. If the zone controller is following itsown local schedule, this is the result of the local schedule status. Ifthe zone controller is configured to follow a global schedule, thisdisplays the mode last received from a global schedule broadcast.Occupied: Display Range No/YesNetwork Access Read OnlyLINKAGE ZONE — This variable displays if air source link-age is in effect.Linkage Zone: Display Range No/YesNetwork Access Read Only
