Hi All,

When I try to create a new HVAC system, eQUEST (v 3.63, build 6510) closes with no error message or warning. I'm in the detailed edit mode and making 99% of my changes in there (as opposed to editing the INP directly). I've made no changes to the INP since the last time I was able to create a new system (so I don't expect there to be any random errors in there). Strangely, the simulation runs fine, with no errors.

I've tried restarting eQUEST, restarting my computer, and checking through my BDL file. I've tried creating a new system by copying an existing one, and also creating from scratch. I've also tried deleting a system and creating a new one (again via copy and create from scratch), to see if I've hit some sort of HVAC system limit (I have 33 unique systems) - no luck there either.

Has anyone run into this type of error before? Any suggestions on things to try?

Regards,

Peter Worley
