Subject: [Equest-users] Appendix G "riding the pump curve"

To model variable loop flow with a single-speed pump, at least one 2-way valve is needed in a loop. How are people approaching the requirement for "riding the pump curve" in HW and CHW loops per G3.1.3.5 and G3.1.3.10? Set all system/zone valves to 2-way and use the default loop-mimimum-flow ratio of 0.05?

Thanks,
Bill
