Dear All,
I am trying to model primary/secondary hot water pumping system with Primary Variable - secondary Constant. It gives me an error as Â
** Severe  ** Plant temperatures are getting far too hot, check controls and relative loads and capacities
 **  ~~~  **  Environment=P&G GYONGYOS (01-01:31-12), at Simulation time=09/23 15:30 - 15:40
However, the following configuration works fine.Â
Primary constant - Secondary Variable : Working fine
Primary variable - Secondary Variable : Working fine
I would appreciate if someone help me on this.
Thanks.
