how much rain will evaporate, and mapping this number against the
known amount of fallen rain, the controller will intelligently know
when it is safe to turn off the rain alarm (i.e. when enough rain has
evaporated that we are below your defined alarm level.)
• The soil holding value is also a parameter: since you can never
benefit from more rain than the soil is capable of holding, the rain
alarm will not stay on forever after a few days of intensive rain.
• If it rains intensively for more than an hour you may get so much
water that the soil can not benefit from all of it ‐ the excess water
will simply run off the surface. So if you run programs in ET
corrected mode, the controller won't subtract all of the rain from
tomorrow's ET figure ‐ it will "cut off" the amount of rain to subtract
at the hourly maximum.
Example: If the hourly maximum is 0.02" and it rains 0.03" per hour
for three hours, only 0.06" and not 0.09" will be subtracted from
tomorrow's ET budget.

Note: If you have not provided any historical ET, a default of
0.20" per day is used. See the NLC User Manual.
