An update to version 2.xx is only possible with the 1.10 version. Older firmware versions have to be updated to version 1.10 first (version 1.10 is available for download below).
The version number of the firmware version currently installed on the controller can be read from the Status / Messages menu.
The update cannot be reversed! After the update to firmware version 2.xx from version 1.10, a downgrade via the SD card will not be possible!
A downgrade can only be carried out by RESOL. For this purpose, the device has to be sent to us. The downgrade is not free of charge.
Data loss! When the firmware version 1.10 is updated to 2.xx, all data logged in the DeltaSol® BX Plus as well as the configuration of the device will be deleted! Store all adjustments onto an SD card before running the update! After the update, the adjustments have to be restored manually.
Due to the vast changes, a changelog is not available for the firmware version 2.05. More information can be found in the manual.
