Hi everybody,
i'm new on this forum. I use Trnsys since 1 month now.
I just want to make a simply SDHW system with a type 60d tank. This
tank has just a heat exchanger (for the solar system) and a electrical
resistance.
For my SDHW, i use a single speed pump, a solar collector and the tank.
My problem is when i connect the temperature exiting the heat
exchanger to the pump. Then i have many "warning" (unit12,type60); i
don't know why.
I know that when i reduce the convergence and integration tolerance
(0.1 for example) then i have less "warning" message but i find that
those parameters have a big impact on the final results...
So if someone have a solution...
Thank you a lot
Best regards Jean
