Next Unoccupied Day — This variable displays the day when the next associated zone is scheduled to change from occupied to unoccupied mode. This point is read in conjunction with the next unoccupied time to allow the user to know the next time and day when a zone will become unoccupied.

Next Unoccupied Time — This variable displays the time of day when the next associated zone is scheduled to change from occupied to unoccupied mode. This point is read in conjunction with the next unoccupied day to allow the user to know the next time and day when a zone will become unoccupied.

Previous Unoccupied Day — This variable displays the day when the last associated zone changed from occupied to unoc- cupied mode. This point is read in conjunction with the previ- ous unoccupied time to allow the user to know the last time and day when a zone became unoccupied.

Maximum Damper Position — This variable displays the damper position of the zone controller in the system with the damper in the most open position. This is used by the linkage coordinator to calculate the static pressure reset.
Maximum Damper |
| |
Position: | Display Units | % (open) |
| Display Range | 0.0 to 100.0 |
| Default Value | 0.0 |
| Network Access | Read/Write |
Static Pressure Reset — This variable displays the current static pressure reset calculated, using the maximum damper po- sition and the configuration information from the linkage con- figuration table.
Static Pressure |
|
|
Reset: | Display Units | in. wg |
| Display Range | 0.0 to 5.0 |
| Default Value | 0.0 |
| Network Access | Read/Write |
Pressure Decrease Value — If the maximum damper position in the system goes below the minimum configuration setting, the linkage coordinator will calculate an amount that the static pressure should be decreased. This is used to open the system dampers more so that they will modulate between their mini- mum and maximum settings.
This number is rounded to the nearest tenth of an inch and will be added to the static pressure reset value unless the static pressure reset value has reached maximum reset.

|
Value: | Display Units | in. wg |
| Display Range | 0.000 to 5.000 |
| Default Value | 0.000 |
| Network Access | Read/Write |
Pressure Increase Value — If the maximum damper position in the system goes above the maximum configuration setting, the linkage coordinator will calculate an amount that the static pressure should be increased. This is used to close the system dampers more so that they will modulate between their mini- mum and maximum settings.
