Subject: [EnergyPlus_Support] Solar collector performance and control

To determine the solar collector performance we have to specify the "Test correlation type" and three coefficients. What do they mean? I know that it is explained in ASHRAE 93-2010, but it costs 54$ and I need to know only one equation :-)
Another issue relative to solar collectors: how can I impose the control of the pump which sends water to the solar collectors? I want to impose that the pump works only if the temperature which exits from the solar collectors is higher than the temperature which exists from the storage tank.
Best Regards
Francesco Passerini
