ASC_Closed-Loop Heat Pumps

Hi,

I’m studying HVAC systems, and I noticed that the Architect’s Studio Companion doesn’t show a thermostat in the graphic for the closed-loop heat pump system. I assume this is to prevent any area from overheating, which seems to be the main idea of the system. But how can you control the temperature from the boiler? Is it done at the control valve?

Thanks!
