The Upgrade Kit for your "old" aquastream pump (all revisions) includes all the necessary parts to upgrade your existing aquastream pump on the functionality of the current aquastream. The only difference is after the upgrade is the lack of built-in pump Internal water temperature sensor of aquastream. The upgrade kit to the "Ultra" version of aquastream is an appropriate temperature sensor can be connected instead of the internal sensor. The external temperature sensor input is still available in addition.

The pump controller that came with the aquastream can be mounted directly in the pump either at the rear or alternatively mounted on the existing mounting holes on the board in the PC housing. For mounting in the pump housing, a new housing cover for the pump is also required, which has the corresponding cutouts for the connector of the pump controller. This cover is only included in the upgrade kit to the "Ultra" version included and must be purchased separately for the other releases.

All versions:
- Microprocessor control with outer optimized control of the pump and USB interface for communication with the PC
- Continuous measurement of supply voltage, power consumption and the recorded line
- Speed signal output with parameterized functions and alarm function
- Venting program
- Aquabus interface for connecting to other Aqua Computer devices
