Hi,

I am trying to model packaged single zone heat hump systems (System 4) per ASHRAE 90.1 Appendix G. I use the "Unitary - DX Heat Pump (Two Speed cooling) - Cycling - Elec reheat" object from the library. It has been fine for the first two zones but then when I continue to do the same for the third zone onwards, I have got the following error.

Could anyone please advise why I start to get this error even though I use the same object and modeling method that do not give any error with the two previous zones?

Thank you.
