The Severe Error is telling you that the zone air is very cold (~55F), and that the air coming into the zone is almost the same temperature (~55F). I would check the zone heating setpoint.

The Warning is saying that your people activity schedule is outside the expected range of 70-1000 W/person. If this is wrong, fix this and re-run, because it may be related to the Severe Error above. Here's how you check it:

First, find the people object, then find the name of the activity schedule assigned: image description
