Is there a way to control the sequence of heat exchangers on the demand side of the plant loop?

I have a system with solar collectors that supply heat through a water loop to two heat exchangers. The first heat exchanger serves the domestic hot water loop to meet the building's hot water demand. The second heat exchanger is connected to the ground source heat pump loop and rejects heat into the ground to improve the efficiency of the system.

I would like to control the sequence of operation of the heat exchangers so that the second one only works when the hot water demand of the building has been met, and there is extra heat to reject into the ground. Is there a way to do this in OpenStudio or EnergyPlus?
