New software version 3.0.4 for MyVallox units

Vallox will release a new software version (3.0.4) for MyVallox ventilation units in the first week of May 2025. If your ventilation unit is connected to the MyVallox Cloud service, it is updated automatically if your current software version is 2.0.18 or later. You can follow the software update process on the control panel. The update progress is shown as a percentage at the top of the screen.

What is changing?

The new Timed function allows you to set a specific ventilation mode for a certain period. For example, you can activate the Away mode for the duration of a holiday. During this period, if the ventilation mode is changed from the control panel, for example, the unit switches automatically back to the timed mode when the day ends.

The new software makes sure the ventilation unit’s defrosting function is working correctly. If the resistors are deactivated, the unit selects ‘Stopping the fan’ automatically as the new defrosting method.

The control panel indicates if the unit has an error and if the error is critical. After the software update, errors are better identified in the MyVallox Home and MyVallox Cloud interface and the latest error is displayed even if it is not critical. The error message disappears when it is acknowledged in the error log.

In addition, minor icon and text changes will be made to all interfaces.
