is there possibility to modify this program?
I have 3 pumps, which needs to change every 10 hours but they also work depending on pressure.

example: pump1 is ON when pressure is -0.5bar and it stops when pressure is -0.6bar

If pump 1 can not reach pressure of -0.6, then pump 2 starts at -0.4 bar and they both switch OFF at -0.6.

If pressure is rising, then pump 3 needs to start at -0.2 bar and all three stops at -0.6 bars.

And as I already mentioned, they need to change over every 10 hours, so first 10 hours pump 1 is MASTER then next 10 hours pump 2 and so on.

this is program so far what I did

Split from change order of lead pump.

hello

spavic7,

I'm assuming that you mean that if the pressure continues to rise despite pump 1 being in operation, pump 2 will switch on.

It looks as if you have integrated a failover in your program. This makes little sense to me, however, since the staggering of the pump switch-on points means that the next pump works the same way up to the switch-off point.

Unfortunately, the program is quite confusing due to the separation of the connections. So a suggestion from me.
