[Comsol 3.5a heat transfer]heat flux depending from other boundaries temperature

Hello
I have a 3D model, i would insert heat flux in one boundary(called A), this flux has two part,a fixed part and a second part that changes with the temperature of another boundary(called B).
What is the way to write the second part?
I try to use projection coupling variable, I call the T of the B boundary with the name T31, and I project this variable on the boundary A. After this work I write in the heat flux box of A boundary: GR*sigma*(T^4-T31^4) where the GR and sigma are costants that I know.
Is this a right way?or is there a better way to proceed?
Thank you
Luca

For a similar application, I have successfully used extrusion coupling variables.
