Yes, it is possible to simulate this. The vertical ground source heat exchanger is a passive device and it will heat or cool whenever there is flow through it. So to turn it off, you would need to put it on its own plant loop and use fluid to fluid heat exchanger to connect that ground loop to the source loop that serves the heat pump(s). The control over ground loop flow is provided by the heat exchanger dual setpoint controls. For such loops that serve both heating and cooling you want to use component setpoint based operation.

Subject: [EnergyPlus_Support] gshp with heat recovery
We are designing a ground source heatpump system with heat recovery. in this system if there is simultaneous heating and cooling load there is direct transfer of energy without exchange with the ground loop. Any additional heating and cooling is obtained from the ground loop. is it possible to simulate this in energy plus.
thanks,
Raj
