Raumthermostat II 230V Installation

[Chaifoo]

Dear Community,

I currently have a underfloor heating 230V and I am in the process of installing the Bosch Raumthermostat 230V. 

The existing uponor product has the following wiring.
N = Neutral (blue)
L = Leiter (Brown)
Black on a heating icon

How do I connect these to the Bosch device?

The wires 'L' and 'N' is clear. where does the black one go? To 'NO' on the bosch device?

Thank you.

Yes, just like in the schematic. Black to NO. And COM needs to be bridged to L.
