To use more than one poweradjust with the aquaero you will have to change their aquabus IDs. To do this, connect them via USB and use the older aquasuite 4.72. Make sure that they use the latest firmware (do an update if necessary) and change the ID between 50 and 55 so that every poweradjust controller uses an unique ID in your setup.
For the problem with the firmware update of the aquaero you can try to perform a full reset of the device. This normally helps. Follow these steps:
1.) Turn off the PC and remove the standby power if you are using it.
2.) Remove all sensors from the aquaero.
3.) Place four jumpers on the temperature sensor connectors 5 to 8.
4.) Power on the system and after a few seconds you should see a recovery mode screen in the aquaero display.
6.) Turn the PC off and remove the jumpers from the aquaero.
7.) Start the PC and use the latest aquasuite 2012 software to flash the firmware onto the aquaero. It should perform a restart afterwards so you should see the regular screens now.
8.) Turn off the PC, connect all sensors etc. again and start the PC.
For the screen: if your aquaero does NOT look like
this one, then you own an older variant. Just write an e-mail to us to get a new cover for exchange. It should solve the problems with the hypersensitive keys.
