Nibe VVM S325

[azachar]

Hi there,

The official integration for Nibe heat pump supports S325 or VVM325 but not VVM S325 (which I do own).

When I tried VVM325 I was unable to connect, but when I tried S325 i was able to connect, but then I was not sure if this won’t make any wrong writes to registers via modbus.

Do you have any suggestions how to proceed?

Perhaps it is just a doc update.

Thank you!

Here is a repo with an official documentation :

Here is the English version - https://professional.nibe.eu/document/Technical%20information%20(TIF)/M12676EN.pdf

As you can see Nibe uses the following official names:

And yet there is a difference between VVM 325 and VVM S325.

Hope it helps!
