Dear all,

I encounter an issue when trying to adapt the "EMSWindowShadeControl.idf" model using the OnIfHighOutdoorAirTempAndHighHorizontalSolar control. The results I obtain are surprising because the shading device is ON (graph #3) when the outdoor temperature is below 25°C.

@smartiz you mention a "graph #3", but there isn't any graph in your post. Can you edit your post to attach or provide a URL for the image?

Thank you for your response. Since my post, I managed to resolve my issue by examining the "WindowTests.idf" model. Here is the chart I was expecting.
