Hi Mike,<div><br></div><div>without looking at your modeling files directly, it may be an input issue at your airside level. If you have a hot water loop system, then it is likely that on your airside heating tab you do not have an input value for your reheat delta T. This needs to be entered in most cases to generate a heating demand on the hot water loop. I suggest checking your input on this tab and using a starter number of 30 F for a delta T. see if this corrects your error.</div>
<div><br></div><div>Other than that, I suggest that you post your .pd2 & .inp file (maybe your weather file too if it is a custom file) and letting someone on this list take a look at your file to help you troubleshoot your issue for corrective action.</div>
