I have read this thread but it couldn't answer my question.


The sentence:

When you are in front of the house dial the number 0 on the door phone and press the green button to ring.

Would "when you will be" be correct?

AskewWould "when you will be" be correct?

No. When when begins a temporal subordinate clause, the future tense cannot be used except perhaps in some rare cases when will indicates desire or willingness, which meaning is a remnant from the days of Old English. Also, there should be a comma after house in your sentence.
