Run Time Limits
Set limits on the highest and lowest Seasonal Adjust
percentage the ET Manager can use.
Minimum Run Time (default 80%)
The Minimum Run Time determines the shortest watering run time
that can be applied to your landscape. Setting this percentage to a low
number means that the ET Manager will allow watering even if only a
small amount of evaporation has occurred. Setting this percentage to a
high number will delay watering until more evaporation has occurred,
providing oxygen to the roots that encourages them to grow deeper,
without sacrificing the health of the plant.
If watering days are limited, the ET Manager looks ahead each day
to determine if watering should occur, based on the last 24 hours of
evapotranspiration. If the current Moisture Level has not yet met
or dropped below minimum levels, the ET Manager will ignore the
Minimum Run Time limit to fill the moisture level in preparation for the
upcoming day(s) that are turned off.
Maximum Run Time (default 120%)
The Maximum Run Time determines the longest watering run time that
can be applied to your landscape. There may be instances where your
landscape has dried out more than a regular watering cycle will be able
to replace. In this case the ET Manager will adjust the Seasonal Adjust
percentage above 100%, causing your irrigation system to run longer
than normally scheduled. Also, the Maximum Run Time can be used to
set a specific limit on watering run times.

NOTE:
The ET Manager is programmed to keep your Moisture
Levels at full capacity and will not set a Seasonal Adjust percentage
that would cause the Moisture Level to go too high.
Run Time Limit Example
If the watering run time is set to 10 minutes, a Minimum Run Time limit
of 80% means the shortest possible run time would be 8 minutes. A
Maximum Run Time limit of 120% means the longest possible run time
would be 12 minutes.
