<p class="MsoNormal">I have run into this problem as well. In no case was I able to control multiple boilers on a water loop serving heat pumps. Similar error as you are reporting. Tested the multi-boiler setup (with equipment controls and load management)
on a hot water loop serving heating coils and it worked fine. My workaround ended up being a spreadsheet calculation to determine the composite efficiency of the multiple boilers, based on running them on a hot water loop in a different model, and applying
that to the single water-loop boiler. Not very satisfying but I had to move on.<o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:11.0pt">Is there a set of conditions where the staging ends up with a blank and no equipment is enabled? What’s the temperature profile on that day compared to the rest of the year for your weather file – maybe there
is temperature that exceeds your staging commands. <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">How many different boilers and boiler efficiency combinations are there? I’d also consider running with a simplified boiler setup without the load management until the rest of the model is complete and calibrated
and then layer in the extra boilers and their staging.<o:p></o:p></span></p>

load management and Equipment control tools for the heating on the WLHP. However I keep running into issues in June 16. I'm having a hard time debugging the problem since the program stops on the certain date. The error code is below.<o:p></o:p></p>
