[Equest-users] Difference in Heating Energy - Identical SYSTEM application

[PKConsulting]

John,    What's up buddy... Haven't crossed your path in awhile.    

Why don't you choose the system type- "heating and ventilation",   You should be able to simulate hydronic heating with ventilation , but no issues/inputs for the cooling side.

Send me your file if you want me to look at your current system approach.

Cheers!
