3.2 Upgrading From Previous Versions
It is strongly recommended to upgrade your HygroGen2 to at least software version 2.0. Version 2.x
contains numerous core system improvements over version 1.x.x, including robustness against power
outages, water level sensor calibration and compatibility improvements. Each version is a free upgrade.
If you are upgrading the HygroGen2 from 1.x.x, it is strongly recommended the HygroGen2 is serviced.
This will allow hardware updates to maximise the performance of the V2.x.x software. These include
connecting the internal network cable and updating the power shutdown hardware.
The Enhanced Features described in
are unlocked by purchasing the appropriate software
code from your ROTRONIC dealer.
To install version 2.1, you will first need to install version 2.0.
