If you are not worried about over-heating your storage tank water,
then you can set the pump to start, when the collector is 5 to 10 degrees warmer than the tank.
Turn off the pump when tank temp = collector temp.
A problem might occur, if you have too much collector gain and your tank temp
gets so hot, the controller shuts the pump off. And the collectors over-heat.
Your coolant or collector might be damaged.?. IIRC, it's called Stagnation.
I think the type of damage depends on system components used.
