Difference between vnbgpo vs vnbgpodb

Hi i installed vmbgpos in my house,

but now the vmbgpodb is released i want to use one of my vmgpo panels also as thermostat, is it possible to upgrade the module? or are there real hardware differences?

There are only two products, VMBGPO and VMBGPOD

Both products have two versions: black version (B) and white version (W)

The thermostat for the VMBGPO can only be adjusted through VelbusLink
The thermostat for the VMBGPOD can be adjusted through VelbusLink and through the panel itself

The VMBGPO can not be upgraded to VMBGPOD
