In order to postpone the irrigation some days, a
variation would, for example, irrigate in alternate days
but waiting initially 8 days: “Frequency 02(08)”, once 8
days have been taken away, the meter will take the
programmed ones.
Another irrigation modality would be pressing the
“MODE” key in order to work by daily
activations
. At
this modality the irrigation is carried out every day,
having the possibility to make several activations,
separated by a time to be determined by hours and
minutes. The first activation will take place at the pro-
grammed starting time. It will not perform a next start
until all activations have been finished. For further
options, please see section [4.11.3].

The “
Start
” value corresponds to the time the
program will be activated. The
timetable
format is
from 00:00 to 23:59. The time 00:00 is not valid. Be-
cause of this reason the program will not work by
temporization.
There are some variations for the starting which
are the next:
The program can be started when
another ends
.
This programs enchainment is done by pro-
gramming at the starting time the value 99 (as the
enchainment code) and at the minutes the num-
ber of the program which precedes it. According
to this, as each program can deal with an irriga-
tion sequence of 12 sub-programs, when en-
chaining them will increase to 24, 36, 48, etc. If
the preceding program has various activations, it
will enchain at each one of them. Besides this the
first program moves the manual factor and the
determining factors to the following programs.

The program can be started by an element
(thermostat, level, etc.) connected to a
digital
sensor
with starting functions. To do so, it is nec-
essary to configure a determining factor at pro-
gram parameters [sector 6.7.]. The Agrónic 4000
allows to work the 4, 5 and 6 base determining
factors, thanks to the fact of being already dis-
charged. For the rest of determining factors it is
necessary to activate the determiners options.
Having the determining factors function installed
the irrigation can be started when a sensor value
(soilmoisture, temperature, etc.) reaches a de-
terminate level. It is necessary to configure a
type
1 or 2 determining factor
at program parameters
[sector 6.7.]. In order to program the reference
value to set on the starting, the “MODE” key has
to be pressed when the cursor is at the start va-
lue.

Having the determining factors option installed,
an irrigation by integration of a sensor (solar ra-
diation normally) in relation to the time lasted
since the previous irrigation can be started. It is
necessary to configure a
type
3 determining fac-
tor
at program parameters [sector 6.7.]. In order
to program the reference value to set on the start-
ing, the “MODE” key has to be pressed when the
cursor is at the start value. At the programs con-
sultation [sector 12.2] the integration which is be-
ing accumulated at each moment can be seen.
Each time an irrigation takes place, the total by
integration goes to 0.

In the second line of the starting conditions
screen, the
pre-irrigation
and the
post-irrigation
which will work is requested for each one of the sub-
programs.
The units that here have been programmed will
be discounted when irrigating in relation to the irriga-
tion units of each sub-program, in order to regulate
the application of the fertilizers to the irrigation water.
The fertilization will always start when the pre-
irrigation ends, finishing when the time or volume of
programmed fertilizer ends, but, avoiding always the
application of fertilizers during the post-irrigation units.
The following value is the
irrigation manual fac-
tor
(F=+00%), with which we can modify in more or
less, the irrigation values of all the sub-programs by
modifying only this value.
This value is calculated each time a sub-program
starts the irrigation. With the +00% value the same
units are maintained.

Having the determining factors option the fertiga-
tion can be modified by the climatic factors, once con-
figured at program parameters [section 6.7].
In order to program the
determining factors
, the
“MODE” key has to be pressed when the cursor is
placed at the “manual factor”, and give a pulse for
each configured determining factor. In order to give
room to the factor and to the determining factor refer-
ence value, the text “Pre/Post” disappears and these
units are moved to the left.
