Agrónic 52

Agrónic 52

Controller that performs the continuous mixing of two waters

to achieve a programmed conductivity,

by the use of one or two motorised valves




Agrónic 52 has 3 programs that are initiated by external commands received by the corresponding inputs.

Programming can be carried out either by the desired conductivity level or by the percentage of opening provided for each motorised unit.

Up to 2 motors can be connected. For each motorised unit there is an output for opening and another for closing. The nominal opening time of the motorised valves must be greater than 20 seconds.

There is also an alarm output.

Power supply of the controller at 24 Vac. Optionally at 12 Vdc.

It has 3 inputs to start the programs and 1 input to detect faults. There is also 1 input for the conductivity probe, with a transmitter integrated in the controller circuitry.

Calibration of the probe is carried out using the keypad.

Alarm for EC being able to configure the high value, the low value and the delay in the detection of the irregularity.

Configurable delay for the detection of the start and fault inputs.

Possibility of stopping or not the current program when an alarm occurs.

Motorized valves can also be manually activated.

Configuration of the motorized one that will control the water with greater conductivity, as well as the one that will control the water that we want to save.

Possibility of programming a minimum opening of the motorized ones.


Controller housed in watertight polycarbonate box.


Easy to use and program by means of three keys.


Liquid crystal display with digits 13 millimeters high.



Option to supply 12 Vdc


The Agrónic 52 complies with the CE marking directives.

The products manufactured by Progrés enjoy a guarantee of two years against any manufacturing defect.

Compensation for direct and indirect damage caused by the use of the controller is excluded from the guarantee.
