2.5.2
Triggering irrigation cycles by accumulated light
The previous paragraph explains how irrigation cycles work by default; however as a
special case cycles can be triggered by accumulated light radiation. Instead of
defining the desired number of cycles and desired interval, the user defines a
threshold of accumulated light that when reached will cause the irrigation cycle to be
executed. This option must be enabled at the
DEALERS DEFINITIONS
.
For defining the radiation thresholds along with some additional parameters the
Radiation sets
are used. How to define radiation sets is explained at the paragraph
Radiation sets definition
in the chapter dealing with
Utilities
.
How do we make a program work by accumulated radiation?
Assuming that radiation sets have already been defined, we need to tell the program
that it depends on accumulated radiation and we have to select the
Radiation sets
to use. This is done at the same screen at which we
Relate Conditions with
Programs
,
see next paragraph
.
The following steps need to be executed:
3.
Use F3 for changing
the program type
1.
Bring the cursor to the
field of program type
2.
Select
“Radiation Sum”
4.
Define which
radiation set to use
