Frequency converter for pump SIRIO ENTRY version 2.0 and XP 230V produced by Italtecnica (Italy) - electronic device for monitoring single-phase electric pumps, the operation of which is based on inverter technology.
Thanks to the use of special technology this device can regulate the frequency (Hz) of the current at the pump motor input and change the shaft rotation speed, depending on the water demand in the system.
In this way, the amount of pressure that reaches the consumption point is constant and the maximum engine power is always proportional to the actual system requirements, resulting in significant energy savings.
Functions:
. Controls turning the pump on and off, and also regulates the shaft speed in accordance with the water needs in the system.
. Constant pressure thanks to regulation of the pump shaft speed.
. Energy saving due to less electricity consumption by the pump.
. Smooth start and stop of the pump reduces the risk of water hammer and also prevents the risk of loss starting current pump
. Protection against “dry running”, which occurs when there is insufficient water in the suction. When the device is triggered during dry running, an automatic reboot occurs with an autonomous recovery mode after a failure occurs.
. Effectively monitors system leaks, which protects the pump from repeated restarts.
. Digital pressure display.
. Current control system in the pump motor.
. LEDs and information on the display indicate the operating modes of the device, as well as the occurrence of errors.
. Operation in modes: main / auxiliary in dual pumping stations.
. Possibility to set two maximum pressure values with remote control function.
. Remote activation and turning off the electric pump.
. Removable terminal blocks for simplified electrical wiring.

This frequency converter has been developed to control pumps in domestic applications. Submersible pumps in wells, pumps in water supply and heating systems - this is exactly the area where they are well used. : Single-phase input and output. Three-phase motors They are rarely used in everyday life. Single-phase design significantly reduces the cost of the product. Enough high price this converter is apparently due to increased demand for a very useful new product.
The sirio converter controls the pump using a pressure sensor, which saves energy by almost half. The power of the motors used with the converter ranges from 1500 to 2000 W. The pressure sensor (there is also a flow sensor) is structurally built into the converter (an inch and a quarter fitting). Settings are made using the remote control of the built-in controller. Please read the instructions carefully regarding hydraulic connections!
The electric motor used with the converter must be single-phase. Three-phase can also be used, but it should be switched to star and a phase-shifting capacitor should be used.
Setting up the sirio entry 230 frequency converter
In the main menu of the display, you can scroll to change the display in next order: pressure and frequency, voltage and current, inverter temperature and display language. For initial setup, you should put the converter into standby mode (the control system is running, the engine is not), press the + and – buttons and hold them pressed for more than 5 seconds. The setup menu appears. It scrolls as before, using arrows. In this menu, use the + and – buttons to set the following parameters:
- Pmax – maximum pressure, pump stop;
- Dp.start – delta for starting the pump (hysteresis);
- P.dr.ru – dry operation pressure, pump stop;
- P.limit – maximum pressure, with complete shutdown;
- Pmax2 – another maximum pressure setting;
- Dp.stop – delta for overpressure protection;
- Unit – unit of measurement (bar or ft. per square inch);
- I.max – current limitation through the pump motor;
- Rot – direction of rotation, conditionally.
In addition, there is also an extended menu with many functions. All that can be said about the advanced menu is that the user of the pump, even a plumber, should not change anything there. The parameters available there are intended for service technicians frequency drives. If the consumer gets there and changes something there, then he must know exactly what he wants. Otherwise, he may have an excellent opportunity to find out prices for a new motor or converter (or both).
A hermetically installed and correctly configured sirio converter, complemented by a 10-20 liter hydraulic accumulator, works quietly and unnoticed, and perfectly maintains water pressure in the home system.
The season is in full swing, I’m finally getting gas after 2 years of ordeal, well, that’s just the way it is
Now the promised report.
I bought a frequency switch and a pressure gauge directly from the site, called the phone number listed on the site, email They sent me an invoice, I paid and literally the same week they sent it to me transport company. I paid about 500 rubles for shipping to the Moscow region.
Here is the hero of the occasion, without the front cover yet.
The photo is not very good, I took it on a tablet. The frequency generator itself is still on the floor; there is no time to hang it on the wall. About the size of a children's shoe box:I bought a pressure gauge for it there:
When I took it out of the box, I couldn’t believe it, it’s the size of a saucer
They still sell it on their website expansion tank, but I didn’t take it, there are plenty of them in every market, so I bought the first one I came across for 5 liters and installed it.About the installation, everything is installed in an elementary way, so I already prepared the place and welded everything to the pipes in advance, then I just screwed on the pressure gauge and that’s it, and I bought adapters on the market, because my entrance is welded to an inch.
I didn’t bother, and connected the pressure gauge to the frequency switch with a simple 2x1.5 wire. I took out the wires from the frequency switch and connected them to a simple socket, and then I plug the plug from the pump into this socket.
There are no photos, but if it’s not clear in words, I’ll take a photo tomorrow.Now about work. I have a well at 80 meters, the water surface is 50 meters from the surface, the water is clean, there is no scale or rust, and therefore I did not install any filters. The pump is an ASP 1.5C-120-75 aquarium, with a power of 1,600 watts. When I turned it on, the lights blinked during the startup period. After connecting through the frequency converter, they no longer blink; on the frequency converter you can see that it does not spin up the pump right away. Now, during construction, I set it to 1.5 atmospheres, while it’s enough, a 12-liter bucket fills in about 10 seconds.
Well, what else can I say, when the frequency converter is working, the fan turns on, the noise is about the same as from the fan on the processor when it warms up so well, but the sound of water pouring from the tap in the kitchen will still drown out the noise from the frequency converter, so I don’t bother with this, besides I will have it under the stairs in the corridor. Oh, once I set it to 4 atmospheres, I had to wash the construction wheelbarrow, it spun the pump easily and gave out the specified parameters, although my HDPE was torn off the coupling from the pressure, so I’m not experimenting anymore. But I think it will also easily give out 6 atmospheres. Yes, and he immediately showed that there was a pipeline break. And it also shows that there are leaks.
Well, in general, I’m happy with the purchase, and I can recommend this frequency generator to anyone who is thinking about automating their water supply.
