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. Thistank has just a heat exchanger (for the solar system) and a electricalresistance.


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 heatexchanger to the pump. Then i have many "warning" (unit12,type60); idon'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 thatthose parameters have a big impact on the final results...


So if someone have a solution...

Thank you a lot

Best regards Jean
