I have been looking for a way to attach the pump operation in a primary-only chilled water loop to the chiller on-off schedule in energyplus. Even when I have chosen an intermittent operation for the pump, when I set a non-zero minimum flow for it, the pump starts whenever the loop is available even when the chiller is off. I have tried other ways to turn off the pump, like setting up the AvailabilityManager:LowTemperatureTurnOff object. It works better to control when the pump starts and turns off, but still can not attach the pump operation to the chiller. Is there is anyway to do this with a non-zero minimum flow?
