Nothing is wrong....
The PA "Menu Tab" is only active when the USB is plugged in...
When you disconnect the USB from the PA & it's connected Via the "High Speed" Aquabus all the sensors from the PA can be found in the MAIN "AQUAERO 5 MENU TAB" & as it seems you have a pump attached to the PA it will show up in the "FANS" Tab in the Aquaero 5 List of Menu's.... Should show up as Fan #5 I think.
The Temp sensor (only if you have a temperature probe attached to the PA) will show up in the "SENSORS" Tab in the Aquaero 5 Menu list then click the "Temperature Sensor" Menu & you should should see (only if you have a temp probe attached to the PA) the temperature reading of the PA beside the "poweradjust 1" listing...
Hope you can understand what I'm saying
