I have two Variable Speed pumps in a Duty/Standby configuration. Only
one pump runs at a time, controlling to a pressure setpoint. A new stream is being added which will produce large surges in demand. I need to change the code so that the second pump will ASSIST the first
during spikes in demand. What is the best way of coding the assist pump.
1) Just enable the second pump to control to pressure as it normally would. Therefore, you will have two pumps controlling to a pressure.
2) Set the assist pump output to a fixed speed, say 10%. Increase this figure if the pressure remains too low for a time. Decrease when output of Fist pump falls below a preset value (say 25%).
Any ideas?
