[TRNSYS-users] Set 2 or more than 2 AIRNODES

Dear all,

       As we know, the default airnode for one zone is one airnode. But I
want to set 2 or more than 2 airnodes in one zone. Please tell me the
detailed steps how to set 2 or more than 2 airnodes in one zone?

       Furthermore, if I set more than 2 nodes, which advantages has
it better than only one node in one zone?

      Many thanks in advance!

    Br.

wang
