[EnergyPlus_Support] Re: Auto-size and user values

Thank you for your response.

But I tried it and when I am changing the values to the calculated it is resulted with a lot of warnings. For example, I am simulating a VRF system and when I am changing the rated cooling or heating capacity I have a lot of warnings about recalculation of the capacity.
