Michele, You should move both airnodes to one Zone.
To define an airflow between these two zones, you can use Couple (05-Multizone docu) Best, Christoph Von: TRNSYS-users <trnsys-users-bounces@lists.onebuilding.org>
Im Auftrag von Michele Vella via TRNSYS-users I have 2 zones on top each other but there is no ceiling touching them so i did the 2 touching surfaces as virtual surfaces.The problem is I dont know how to couple them together as when i heat the upper zone it is not effecting the temperature
of the lower zone. When i press couple on the TRN build it just shows up the airnode window. Regards Michele Vella |
