Running an Energy Plus model in witch air temperatures should be higher than 100°C I get several errors. Is there a upper bound for the air temperature in zones? Is it possible to override this maximum air temperature? It should reach at least 150°C.

What exactly are you trying model that is so hot? A ceramics kiln?

@__AmirRoth__ I'm trying to model a Shadow box spandrel. It's insulated and it's exposed to the daylight. The model is described in this question:

I don't believe there are limits on the air temperatures but there are limits on the surfaces temperatures. Here the air is being heated by the surfaces so those are the limits that matter. The default surface temperature upper limit is 200C, but this can be changed on input using the HeatBalanceAlgorithm object's input field called Surface Temperature Upper Limit.
