1 DESCRIPTION OF BASIC FUNCTIONS
The Agrónic 2500 is designed for automating irrigation on small and medium-sized farms
(maximum 30 irrigation sectors) where there is a need to open/close sector and master valves,
fertilizer control and filters.
The farm may have a pressurized water intake or need
a drive pump (electric or motor pump). There may be
an irrigation water meter.
The head can have 12 Vdc power supply (with solar
panel and battery, or battery only) or at 220 Vac (mains
or generator set).
The valves can be 12 Vdc, 24 Vac or latch and can be
close to the head and controlled by microtube or cable,
or at distances of up to 2 km connected to AgroBee-L
radio modules.
In the head, there can be fertilization with a hydraulic
pump injector, electric dosing machines or a venturis
system.
Reading of all types of sensors (analog, digital and
meters) connected to Agrónic and also remotely with
AgroBee-L radio modules.
The Agrónic 2500 has an internet connection, with
mobile telephony or WiFi, to connect to the VEGGA
platform or to the Agrónic APP application and
remotely manage the Agrónic.
For remote management, you can also connect to the
Agrónic PC Windows program. The connection can be
with direct USB to the computer, when it is next to the
unit, by radio modem, for medium distances, or by
Internet, with WiFi or mobile telephony.
All the features of the Agrónic are expanded in the
Plus version. If the Basic version does not meet your
requirements, see the Plus version.
To go from the Basic to the Plus version, just activate
an option from the unit.

User Manual | Agrónic 2500
Control up to 30 sectors using 50 irrigation programs.
Each program can activate 1 to 4 irrigation sectors si-
multaneously.
There are three ways to start a program:
Schedule start: at a specific time choosing the days
of the week or repeat the irrigation every few days
(frequency of days).
Days of the week Every 3 days
Sequential start: when another program has finished.
It is used to irrigate several sector groups one aer
another. The first program in the sequence must be
schedule start or conditional.
P6 sequential of P5 and P7 sequential of P6, etc.
Conditional start: when a determining factor is
activated.
The determining factor is related to any type of sensor
and can activate the program, for example, when
the temperature rises, when a buoy is deactivated
or when a flow rate drops below a certain level. An
active schedule and a safe schedule can be configured
between starts.
Conditional start due to frost
Once the program has started, there is an option to
repeat the irrigation every certain amount of time.
At the start, the amount of irrigation can be modified
using the determining factors. For example, increase
irrigation by % if there is a lot of radiation, decrease ir-
rigation by % if there is a lot of moisture in the soil, etc.
Irrigation units can be in time, hh:mm, mm:ss or
hh:mm/ha; or in volume, m3 or m3/ha (m3 per hectare).
A record is made of the irrigation time and volume for
each sector and in total.
When the program is active, irrigation can be stopped,
permanently or temporarily, using a determining
factor. For example, stopping when it is very windy,
stopping while the well level is low, stopping when the
flow in a sector is too high (broken pipe), etc.
2 FEATURES
The Agrónic 2500 is a controller for controlling irrigation, fertilization, pumping and filter cleaning.
It detects malfunctions and creates a chronological record of the events. Fully configurable, with
multiple possibilities for use, communication and expansion.

Description of basic functions
PUMPING
It has 2 general irrigation outputs, or pumps.
One of the pumps can be a motor pump or generator
set. Each sector is assigned with the pumps associated
to it.
The pumps are activated together with the sector.
There are time delays to separate the pump from the
sector activation, during activation as well as stop, to
avoid water hammer.
Configurable from 0 to 4 fertilizers in separate tanks.
Separates pre- and post-irrigation values in each
program.
Fertilization units in time (hh:mm or mm:ss) or in
volume (L or L/ha).
Configured to use mixers, with pre-mixing and inter-
mittent or continuous mixing.
Fertilizers can be applied in three dierent ways:
in series: one type of fertilizer aer another from a
single injector

FILTER CLEANING
Configured for 0 to 9 filters, with selectable cleaning
times. Programmable pause between filters.
Washing sequence may be started by the pressure dif-
ferential and/or according to the time or volume of the
water circulation.
Whether or not the irrigation sectors and fertilizers are
stopped while the filters are being cleaned is configu-
rable.
Control over malfunctions due to continuous cleanings.
Configurable general filter output.
DETERMINING FACTORS
The unit has a total or 30 completely configurable
determining factors to trigger actions that take into
account certain determining factors or values from
digital or analog sensors and meters.
There is a wide variety of actions possible, such as the
ability to make definitive, temporary or determined
stops that are applied to specific programs or all of
them, start and/or stop irrigation, send a warning,
adjust irrigation or fertilizer units when starting an ir-
rigation program according to an instantaneous value
from a sensor or the value recorded from a previous
irrigation, etc. Each determining factor can also be
configured to create a malfunction or send an SMS
message and an SMS message to another machine.
To give a few examples, it can be used to terminate ir-
rigation due to a broken pipe, postpone irrigation due
to the lack of water level or excessive wind, modify the
volume of each irrigation as to the value of the water
content in the soil or the solar radiation the plant
received since its previous irrigation or the evapotrans-
piration, terminate irrigation if a certain amount of
rain has fallen since the previous irrigation, or send a
warning to the owner for an attempted the, etc.

stirred before starting fertilization. Pre-mixing comes
in before the program starts. If it is less than 10 minutes
since the last irrigation, do not start the pre-mixing.
Mixing during fertilization can be continuous or with
pauses.
Mixing start(000 ... 999”): mixing time before a pause. If
continuous mixing is desired, set the mixing pause to 0
and any time here.
Mixing stop (000 ... 999”): time that the mixing will be
stopped aer a startning time. If continuous mixing is
desired, set this time to 0.
Final cleaning (000 ... 999”): when fertilization ends, the
general and fertilizer cleaning outputs are activated
during this time. If the fertilization is in series, it cleans
at the termination of each fertilizer. If it is in parallel,
when the last one ends.
Fertilizer meters
If fertilizer by volume, the meters must be assigned.
When fertilizer is parallel or uniform, a meter must be
assigned to each fertilizer; if it is series, the same meter
can be assigned to all fertilizers.
Meter F1, F2, F3, F4 (0 ... 10): meter sensor number asso-
ciated with the fertilizer.
Flow rate F1, F2, F3, F4 (000.00 ... 655.35): maximum
planned injection flow rate for these fertilizers. The
planned flow rate is used for uniform fertilization.
Uniform fertilization
With uniform fertilization, the fertilizer is distributed,
injecting small doses, throughout the irrigation. This
achieves better nutrient absorption, more homoge-
neous growth, drainage losses and sedimentation in
pipes.
It is applied using simple Venturi-type hydraulic
systems, reducing installation costs and can be done
in time and volume.

The Agrónic can control the filter cleaning. Cleaning
can be started manually or automatically. It starts au-
tomatically by a dierential pressure gage or by a time
or volume of water having passed through the filters. It
will only start automatically if the general one assigned
to the filters is activated. In other words, when there
is a program irrigating. It can be started manually
whenever desired from ‘Function - 2. Manual - 4. Filters’.

filter.
Activation time per filter (000 ... 999”): time that the
water will pass through each filter to perform cleaning.
Pause between filters (00 ... 99”): waiting time between
closing the cleaning of one filter and activating the
next one.
5.2. FILTERS
Units between cleanings (0000 ... 9999): the irrigation
time or volume that must pass through the filters for
automatic cleaning to begin. Time in minutes and
volume in m3.
Filter general (yes | no): indicate ‘yes’ to activate an
output during the entire filter washing process.
Relation with P1, P2 (yes | no): it indicates the pump
from which the water that passes through the filters
comes from. It is used to count units between cleanings
and to start the cleaning.
Maximum number of consecutive cleanings (0 ... 9): if
cleaning is started by the dierential pressure gage
and is always activated, it will do the cleanings config-
ured here at most. It then goes into malfunction and
will not continue cleanings until it is manually recon-
figured. At 0, it never goes into malfunction. To restart
cleaning go to ‘Function - 2. Manual - 4. Filters’.
Stop sectors (yes | no): if cleaning takes place during
irrigation, select whether or not to postpone the irri-
gation while it does so. It is used when sectors must be
closed during cleaning to maintain pressure.
• Yes: programs that have sectors related to the
pump that use cleaning are postponed. When the
cleaning is finished, the programs continue where
they were.
• No: the programs remain active during cleaning
and the irrigation sectors are not closed.

5.3. GENERAL
The pump, fertilizers, filter and diesel outputs are con-
figured in this section.
The outputs can be from the base of the Agrónic 2500, a
recommended option and from external modules such
as the AgroBee-L, an option not recommended due to
the activation and deactivation delays they may have.
Pumps
Output connected to the drive pumps or general valves.
GENERAL PARAMETERS
Pump 1: yes
Temp. start: 018”
Temp. stop: 012”
Stopping the sectors: no
Pump 2: yes
Temp. start: 005”
Temp. stop: 022”
Stopping sectors: yes
Pump 1 (yes | no):
• Yes: i f pump 1 output is to be used. An output must
be assigned to the pump.
Temp. start (000 ... 250”): time delay in activating the
pump when starting an irrigation.
Temp. stop (000 ... 250”): time that the pump stop is
extended when stopping irrigation.
Stopping the sectors (yes | no):
• Yes: for the pump to stop when irrigation is finished
and for the sectors to remain open for a few more
seconds.
Start timing: 018
Stop timing: 012
Stop in the sectors: no
Start timing: 005

Outputs
At the base of the Agrónic 2500, there can be up to 27
digital outputs, identified as R1 to R27, to connect the
general outputs. It is recommended to start with the
unit’s last outputs and reserve the first ones for the
sectors.

MF: output connected to the pump or general fertilizer.
A1, A2, A3, A4: outputs connected to the mixers.
LF: output connected to the fertilizer cleaning valve.
Filter cleaning.
Before assigning the outputs, configure how many
filters there are in the installation. This is assigned in
‘Function - 4. Parameters - 2. Filters’.
L1: output assigned to the first filter.
Lx: output assigned to the last filter.
GL: output connected to the general filter cleaning
valve.
The outputs that occupy the filters between the first
and last are assigned automatically. If there is only one
filter, the last one is not asked.
Example
An installation with 4 filters, in which the assigned
outputs would be: l1 output 10, L2 output 9, L3
output 8 and L4 output 7.
The output number coding can be found in section ‘6
Input and output coding’ of this manual.
5.3.1 Diesel option
This option is used to start, stop and monitor diesel
pumps for malfunctions.
Operation
The diesel pump is related to pump 1. It starts when a
sector that uses pump 1 opens and stops when the last
sector that uses pump 1 closes.
First the sector is opened, the contact and preheating
output of the diesel pump is activated. When preheat-
ing is finished, the start output activates. If the pressure
gage input is activated, the diesel pump has already
started and irrigation begins. If it is not activated aer
the boot time, wait 30” and attempt another boot. If
the diesel pump cannot be started in 4 attempts, the
stop output is activated, it enters ‘Malfunction’ and
makes a record. The pump will attempt to start again
at the next irrigation start.
When irrigation is finished, it closes the sectors and
the pump, carrying out the water hammer timings and
once the end of pump time has transpired, it activates
the stop.
‘Consult - 1. General’ shows the status of the diesel
pump.
These screens only appear if the Diesel Option is
activated.
Pressure gage
A pressure gage is used to detect that the pump is
startning. Its purpose is twofold: to detect start-up
when attempting to start and, once finished, to detect
insuicient oil pressure. In the Agrónic Basic version,
the pressure gage must be connected to digital input 6
(D6). This input cannot be used for any other function.
If you have a generator on which there is no need to
control the pressure gage input, set the start and stop
times to 0.
GENERAL PARAMETERS
Preheating: 08”
Start-up: 04”
Stop: 060”
Pump input: 085”
Pump end: 0120”
Assign outputs:
