Integration heat pump controller ECR450 with Modul RZB571B00 from TEM AG

Hi There,
Wanted to ask if someone already tried to integrate a heat pump with a controller from TEM.
There is the controller ECR450 and as I understood the Modul RZB571B00 needs to be installed - protocol would be modbus.

But I do not have a clue how to integrate it.

Would be super nice if someone can help.
