Aquaero 5 w/ D5 aquabus and tacho

Mittwoch, 20. August 2014, 00:41

Hello, first post here 8)

I'm from Holland so if my english seems a bit off then you know why ;)


I have a question relating my new setup with aquacomputer components, I installed an Aquaero 5 LT, an AC D5 with aquabus. Pump runs just fine but it seems that Aquiasuite can't control my pump. Pump is always running maximum (i think) but i could not see my RPM of the pump, so i connected the aqaubus cable on the alarm connection (according the manuel this could also used as tacho) of my pump and and to the RPM connection of my Aquaero 5 but that did not work,

So i connected it to my motherboard and saw that the pump was spinning at 2270 RPM. So i controlled the power output trough Aquasuite (i am using latest version) but the pump did not go faster or slower, constant at 1 speed.

I have looked at the Aquaero and saw that aquabus has 4 pins and i have connected it with a 3 pin
(93111) cable that was included with the Aquaero and pump as well.


So my question is, i propably need to purchase an 4 pin aquabus cable to correctly control my pump? and if so will i see the correct RPM as well trough the 4 pin aquabus connection? And why when i have connected the TACHO connection on my pump trough my RPM connenction on my aquaero can i still not see the speed of my pump trough aquasuite?

I do not have much information to offer other than I believe the 4th pin on the Aquabus cable is for power. (pin 1 is ground, pin 2 is data and pin 3 is clock).
As the Aquacomputer D5 pump has a separate 4 pin molex for power, the 3 pin Aquabus cable should be sufficient.
If you were to use an MPS sensor (flow, pressure, etc) the 4th pin is needed to power the sensor.

From what I understand, you need to initialize the pumps first via the USB cable to set identity parameters - then you can use the Aquabus and Aquasuite for monitor & control.
If you have not initialized your pump addresses, try that first.

The above is just from my searching for information... I do not yet have a system and could be in error.

Good luck

Thanks for the info, it worked immediately!! :P

Now i can control the pump, i have both cables installed, so i can decide how to control my pump,

The 'RPM' output on MPS devices like the USB pump is just an artificial signal for use with alarms ... it isn't an actual speed measurement. The real RPM's are only transmitter via the USB connection.

I noticed that, in Aquasuite shows it as 0 - 100 RPM, while the digital signal goes from 1800 - 5200 RPM. I still have the usb connected but control goed trough aquabus.

Have any of you noticed that the inlet temp of my radiator is lower whnm pump is running at minimal speed? I did a test at full or half speed but the inlet temp only went up. I think the pump is also generating heat.
