If you configured the system for Variable Speed Pumping with a Pressure Sensor for proof of flow, the Loop Controller can send a signal to all the Heat Pumps to open their Isolation Valves whenever a Hi Limit Pressure is exceeded. If the Heat Pumps do not control an Isolation Valve, then the only reaction is to
