zone and max humidity errors

Hey everyone,

I am having some errors on my simulation.

It’s a single room starting with surfaces --> zone --> decomposed zone to add material properties --> back into one zone. I know it can be done easier, but later on the geometry will change and therefore this seems the better option. But coming back to the problem

First, there were some problems concerning the zone, although it seems solved still the “runenergysimulation” gives the following warning:

1. The simulation has not run correctly because of this severe error:

   ** Severe  ** UpdateZoneSizing: Cooling supply air temperature (calculated) within 2C of zone temperature

Do one of you know what went wrong? It probably will solve most of it.

Second, “set Zone Thresholds”  gives the following warning:

1. Solution exception:global name 'maxHumidity_' is not defined

However, the component is missing the max humidity input on the list, has this to do something with the error?

All the components are up to date.

I hope it will be an easy fix.
