For a reverse range, enter the upper range value as the LRV and the
lower range value as the URV. For example, to make a 0 to 500 °F
range a reverse range, enter 500 as the LRV and 0 as the URV.
The URV changes automatically to compensate for any changes in the
LRV and maintain the present span (URV – LRV). See Figure 23 for
an example.
If you must change both the LRV and URV, always change the LRV
first. However, if the change in the LRV would cause the URV to
exceed the URL, you would have to change the URV to narrow the
span before you could change the LRV
