ATTENTION

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
