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.

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.
