Yes, the pump is the AC D5 USB/Aquabus pump. What exactly do you mean by:
If the pump is model D5 USB aquabus, it is not controlled by power level. Read the manuals.
I saw one reference to this ("not controlled by power level") from someone elsewhere in the forum, but according to the manual:
12. Configuration of the mps device (aquasuite)
......12.5. Pump power
..............Adjust pump power as desired.
Seems clear in the manual, and seems to be supported by the power level slider included in the D5 mps configuration tab...and in this thread
d5-pump-control-via-aquabus-not-responding, sebastian seems to confirm that if you cannot control the pump speed via USB, that the pump has an error:
// no response on speed control (always showing RPM between 3600-3800 with 25-100% power configured)
>>Can you control the pump via USB (you have to disconnect the aquabus)?
// No, speed control is not working even with aquabus disconnected and pump connected only thru USB.
>>In this case your pump has an error, contact our support: info@aqua-computer.de
At this point, I guess my question is: is not the case that I should be able to control the D5 pump speed via aquasuite?
