HVACAvailabilitySched?

Hi,

I'm doing a EP simulation on a zone in a multiple zones building. Adjacencies are solved, and zone schedules and zone loads are set. Yet, when performing the EP this error appears: 1. Solution exception:'EPZone' object has no attribute 'HVACAvailabilitySched'.

The program for the zone is "open office" and all schedules has been set except "ventilation" since natural ventilation i going to be applied to the model.

Has someone experienced this too?

Best regards

Mads
