field — Displays the number of hours

Offset fields — Allows the user to fine tune the balancing of

PB On plus the offset (+/- 10).

difference in pressure drop. If the cycles
for all the units are within an acceptable
percentage (5-10%), it is recommended
to leave the Offsets at 0 to minimize
complexity.
