1. INTRODUCTION
Agrónic 52 is a unit which continuously mixes two
waters in order to obtain a programmed conductivity, by
using one or two motorised valves.
There are 3 formulas or programmes which are start-
ed by external orders received by the corresponding inputs.
The programming can be done either by the expected
level of conductivity or by the opening percentage ex-
pected for every motorised valve.
Up to 2 motorised valves can be connected. Every
motorised valve has an outlet to open and another one to
close.
There is also an outlet for alarm.
Feeding of the unit at 24 Vac. Optionally, at 12 Vdc.
There are 3 inputs for the start of the programmes
and 1 input to detect breakdowns.
There is also 1 input for the conductivity sensor, with
a transmitter which is integrated in the unit circuitry.
The calibration of sensors is done with the keyboard.
It is easy to use and programme by means of three
keys and a LC screen with 14 millimetre-high digits.
There is a CE alarm, being possible to configure the
high value, the low one and the delay in the detection of an
irregularity.
Configurable delay for the detection of start inputs
and breakdowns.
It is possible to stop or not the programme which is
being working when there is an alarm.
The motorised valves can also be activated manually.
Configuration of the motorised valve which will con-
trol the water with more conductivity, as well as configura-
tion of the one which will control the water we want to
save.
It is possible to programme a minimum opening of the
motorised valves.
The unit is located in a poly-carbonate closed box.
Agrónic 52 follows the CE guidelines.

2. SCREEN DATA
Information is displayed on the screen in the following
way: the first two digits indicate the code in which we are.
The following block of digits gives information about the
motorised valve M1, while the last block of digits makes
reference to the motorised valve M2 or to the electric
conductivity.
Use the “C” key to go from one code to the next one.
If you keep pressing this key, the code will change rapidly.
Use the “+” and “-“ keys to modify the values which
are displayed on the screen. These keys will increase or de-
crease the active value which is displayed in that moment.
If you keep pressing the key, it increases or decreases rap-
idly.

5. INPUTS AND OUTLETS
5.1. INPUTS.
The unit has four digital inputs (D1,D2,D3,D4). Three
of them work as switches (D1,D2 and D3), starting or
stopping the corresponding programme, while the fourth
one is a breakdown input (D4).
The activation of inputs is done through their connec-
tion to the common.
A time for the detection delay can be configured for
every input, but deactivation is immediate.
The conductivity reference or the opening percentage
of the available motorised valves can be configured for
every input or programmes 1, 2 and 3. It is not possible to
activate more than one input at the same time.
Input 4, breakdown, is only taken into account if a
programme is working. If it activates, it always stops the
programme, without taking into account the established
configuration.
The unit also has an input for conductivity sensor.

5.2. OUTLETS.
The unit has 5 digital outlets.
Outlets are protected by a 2.5 A fuse F Type (fast). Re-
place it with a similar one if it fuses.
SECTION OF THE UNIT INFERIOR BOARD
- S1, S2: Digital outlets for the opening and closing of
the motorised valve M1. S1 is connected to the closing
terminal of the motorised valve and S2 to the opening one.
If no motorised valve is connected to these outlets, but
there is an electrovalve, connect it to S2.
- S3, S4: Digital outlets for the opening and closing of
the motorised valve M2. S3 is connected to the closing
terminal of the motorised valve and S4 to the opening one.
If no motorised valve is connected to these outlets, but
there is an electrovalve, connect it to S4.
- S5: Digital outlet used for the breakdown warning.
DIGITAL OUTLET CONNECTION
6. OPERATING THEORY
The unit can be programmed in two different ways:
- By opening: In this case, the programmer only opens
the existing motorised valves up to the point indicated in
the programme and it does not carry out any type of regu-
lation. However, it checks whether the conductivity level is
within the established alarm limits.
- By conductivity reference: When the reading of the
electric conductivity (CE) is higher or lower than the speci-
fied permissiveness margin, the programmer corrects the
deviation making minimum movements of the motorised
valve chosen for the regulation. If only one motorised valve
is available, it will be the chosen one. In order to know
whether the programmer has to open or close the motor-
ised valve it takes into account the CE level (high or low CE)
which the water controlled by the motorised has in refer-
ence to the other water.
If two motorised valves are available, the programmer
starts the regulation by opening as much as possible one of
the motorised valves (the one which corresponds to the
cheapest water) and it regulates with the other one. If the
opening of this motorised valve reaches its minimum, it is
not possible to obtain the reference indicated in the pro-
gramme. Otherwise, if the motorised valve reaches its max-
imum opening, the programmer tries to reach the indicated
reference, closing the motorised valve which corresponds
to the cheapest water.
While a programme is working, it is not possible that
the two motorised valves reach their minimum opening,
but it is possible that both are completely open.

7. CONFIGURATION OF THE INSTALLER
This configuration must be done by the installer of the
unit. To access it, press the “+” and “-“ keys at the same
time while being at code C0. Press the “C” key to go to the
following code. Press the “+” and “-“ keys to change the
values. Press the “C” key until the C0 code is displayed to go
back to CONSULTATION.
Do not change the parameters related to the motor-
ised valves if a programme is working or the motorised
valves are moving. It may cause a malfunction in the unit.
In the programming by openings, only codes 10 to 13
are significant.
- Code 00: Programming mode. By opening percentage
(set at YES pressing the “+” key) or by conductivity ref-
erence (set at NO pressing the “-“ key).
- Code 01, 02, 03 and 04: Timings. Indicate, in seconds,
the time that must go by from the detection of the acti-
vation of an input until the programmer takes it into ac-
count. The value must go from 0 to 99.
- Code 05: Alarm outlet: Set at YES (press the “+” key)
so that outlet S5 activates when there is a breakdown.
Set at NO (press the “-“ key) so that outlet S5 does not
activate.
- Code 06: Initial regulation delay. Indicate the time in
seconds that the programmer has to wait before start-
ing the regulation when a programme starts. During this
time, the applied opening percentage will be memo-
rised in the last irrigation. This allows the stabilisation of
the mixing. The value must go from 0 to 250.
- Codes 07: Self-adjustment delay. Indicate, in seconds,
the time that has to go by between an adjustment at-
tempt and the next one. The self-adjustment time is the
time that has to go by since a change has taken place at
the opening of one of the motorised valves until the fol-
lowing change takes place. The minimum time is 4 sec-
onds and the maximum 99.
- Code 08: Permissiveness margin. Indicate how much
the reading of the CE can differ from the given refer-
ence without a regulation taking place. Diminish the
value to obtain more precision. Increase the value to
diminish the movement of the motorised valve/s. The
minimum value is 0 the maximum 0,5.
- Code 09: Higher conductivity water. Press the “+” key
if A1 (water controlled by the motorised valve M1) is
the water with the highest conductivity. Press the “-“
key if A2 (water controlled by the motorised valve M2)
is the one with the highest conductivity.
- Code 10: Available motorised valves. The available mo-
torised valves are changed with the “+” and “-“ keys. In-
dicate A1 if there is only one motorised valve and it is
connected to the outlets S1 and S2. Indicate A2 if there
is only one motorised valve and it is connected to the
outlets S3 and S4. Indicate A1 and A2 if there are two
motorised valves.
- Code 11: Opening time of the motorised valves. Indi-
cate the necessary time in seconds to completely open
the motorised valves M1 and/or M2 being completely
closed. The maximum time is 199 seconds.
- Code 12: Minimum movement percentage of the mo-
torised valves. Indicate the minimum opening of the
motorised valve M1 and/or M2. The values go from 0.1
to 5.0.
- Code 13: Minimum opening of motorised valve M1
and/or M2 while the mixing is taking place. If it is not
possible to get the expected number (due to the mini-
mum movement of the motorised valve) we will ap-
proach at it as much as possible, by defect or excess.
The control values go from 0 to 99.
- Code 14: Water to be saved. Indicate which water you
want to spend the least. Press the “+” key to indicate
A2 (water regulated by motorised valve M2) or press
the “-“ key to indicate A1 (water regulated by motorised
valve M1).

The first two codes of the programmer correspond to
consultations of the unit state (C0 and C1).
- Code C0: It shows which programme is activated (a
hyphen if none is activated) and the conductivity read-
ing in mS which reaches the unit through the sensor. If
a breakdown takes place, the programmer shows this
code and the alarm origin (programme number) in-
termittently, and the reason for it (high or low con-
ductivity, breakdown input). For further information
read the section BREAKDOWNS.

9. PROGRAMMING
The codes that go from C2 to C4 are used to define
every programme, having to specify either the desired level
of conductivity or the opening percentage of the motorised
valve.
When programming openings, every code is divided
into two sections. The first one corresponds to values of the
motorised valve M1, while the second one corresponds to
values of the motorised valve M2. The opening of a motor-
ised valve can not be varied if it is moving.
Press the “C” key to change section or code and
the “+” and “-“ keys to increase or decrease the value of
the section which is active, that is to say the one which has
a blinking point on its left.
When programming the conductivity level, codes
C2, C3 and C4 are used to indicate the desired reference
value for conductivity (value from 0 to 9.9).

10. CONFIGURATION OF THE USER
In this section we can find the parameters which allow
you to adjust the working of the unit, as well as the sensor
calibration and the manual activation of the motorised
valves. To access this section, press the “C” and “+” keys at
the same time when the programmer is at code C0 of con-
sultation.
If no input is activated, the programmer goes to sen-
sor calibration; otherwise, it goes directly to the first con-
figuration code (code 03).
Press the “C” key to go from one code to another. Use
the “+” and “-“ keys to change values. Press the “C” key,
until code C0 appears, to go back to consultation.
Codes U0 and U1, which correspond to calibration, are
explained in the CALIBRATION section.
- Code U2: Manual activation of the motorised valves.
The first section corresponds to the activation of the
motorised valve M1 and the second one to the activa-
tion of the motorised valve M2. If one of the motor-
ised valves is not available, the corresponding section
does not appear. When the opening percentage of any
of the motorised valves is varied, the indicated
movement will be carried out. Set value 0 at the mo-
torised valves to finish the manual opening. While it is
at manual a flashing dot appears just at the end of the
option code. It is not possible to activate any pro-
gramme while in manual mode. It is possible to vary
the opening of a motorised valve if this one is in
movement.
- Code U3: High and low CE alarms respectively. If the
programming is done by reference of conductivity, en-
ter, in the first section, the difference that there has to
be above the indicated reference in order to activate
the alarm, as a level of conductivity which is too high

7
has been reached. If the programming is by openings,
indicate the maximum conductivity value which is al-
lowed. Values go from 0.0 to 9.9. In the second section,
enter the difference there must be below the expected
reference so that the alarm activates because it has
reached a level of conductivity which is too low. If the
programming is by openings, indicate the minimum
conductivity value which is allowed. Values go from 0 to
9.9.
- Code U4: Delay in alarm detection. Indicate the num-
ber of seconds during which conductivity must be at an
alarm level before its activation. The value must be be-
tween 0 and 999.
- Code U5: Indicate whether the active programme must
be deactivated when a breakdown takes place (press
the “+” key for YES to be displayed on the screen) or it
must continue its working (press the “-” key for NO to
be displayed on the screen). In the last case, the en-
trance of another programme will not be allowed. This
value does not affect input nº 4, which will always stop
the active programme.
- Code U6: Alarm working and at stop. In the first sec-
tion, indicate the number of seconds the alarm must be
working in the cycle of alarm signal. The value must be
between 1 and 99 (0 means “do not start”). In the sec-
ond section, indicate the number of seconds the alarm
must be at stop in the cycle of alarm signal. These val-
ues must be between 0 and 99 and it only has sense if
outlet S5 has been programmed as alarm outlet (0
means alarm always working, if there is time in the pre-
vious section).
11. CALIBRATION
In the configuration of the user, codes U0 and U1 are
used to calibrate sensors. In order to carry out the calibra-
tion, take the sensor out of the pipe and leave in a place
where it has no contact with water. Next, go to code U0. On
entering in everyone of the codes, the code and value
which is expected from the sensor appears for a few sec-
onds. After these seconds, the screen blinks and displays
the reading which is being obtained from the sensor. If the
reading is stable enough and similar to the desired one, the
screen stops blinking after ten seconds, indicating that the
sensor has been calibrated. Pressing the “+” and “-” keys at
the same time the unit is forced to accept the value which
is being displayed on the screen at that moment. Once this
point has been reached in the code U0, deep or fill the sen-
sor with pattern liquid of 5.0 mS and press the “C” key to
change to code U1.
If the calibration of sensor is not to be done, press the
“C” key during the initial seconds or press the “C” key until
the code changes, when the screen is blinking.
In order to have a good calibration, the sensor and
the liquid have to be as close as possible to 25ºC degrees.
Then, the liquid value and the automatic compensation
that the sensor have will be correct. If the irrigation water is
cooler than 25ºC the sensor it should be taken out for sev-
eral minutes because the sensor has and inertia to the
temperature changes.
If a suitable calibration is not done in the first code,
the second one does not appear. So, to do a valid calibra-
tion of the sensor, it is necessary to do the two codes cor-
rectly.
12. BREAKDOWNS
When the unit detects a breakdown, because a non
desired level of conductivity has been reached or because
input 4 has been activated, the screen displays the consul-
tation code C0 and the information about the reason of the
breakdown in a blinking way. This message will disappear
on pressing the “C” key. If it has been indicated that the
programme has to stop, the action will take place and the
activation of another programme will not be allowed. If ,
apart from that, it has been indicated that outlet S5 works
as alarm outlet, it will activate according to what is indicat-
ed in the configuration of the user.
