You can only update the firmware within a series. The numbers before the dot describe the firmware series. The numbers after the dot represent the firmware version. If you have a higher number than the one described here, the latest firmware is already on the fuel cell.

If you have an older firmware version than described above, request the free EFOY Updater now using the order form or ask your local dealer.

After successfully updating your fuel cell, please return the Updater to us in the enclosed stamped envelope. If the EFOY Updater is not returned within 4 weeks, a fee of € 50 will be charged.

How you can read the firmware version of your fuel cell via the control panel is explained in the Operating instructions for the fuel cell. Alternatively, you can read the firmware version in the EFOY App. The operating instructions for installing the update will be sent to you with the Updater.
