WBjr regulating aux1

[heinburgh]

I'm posting this in both WBjr and Classic forums with the hope that the guys that know will spot this. I run a 5.4kW pv array with 2,200Ah battery bank. Every morning at around 10am (12pm in winter) the batteries are at around 95% SOC according to my WBjr, at which stage there is enough juice being turned away to run my 0.75kW irrigation pump that water a 2 acre piece of lawn. I'm having trouble setting up my aux relays to maximise irrigation time while making sure my batteries stay as healthy as they possibly can.

Currently I have one Classic set up to close aux1 when batteries reach 95% SOC. I have a second classic's aux1 set up with 'do not waste high', and I wired these two so that both relays have to be closed in order to switch on the pump. So when either of the two relays opens, the pump switches off. Switching on using SOC works great, it happens right when there is enough amps being wasted to run the pump, but switching off I just cannot get right.

Using the 'waste not high' feature works well except when the system is in float when it is meant to shut down the pump, for some reason the aux1 relay remains closed and the pump keeps on running even though there's not much sun left, draining the batteries. I have tried using WBjr SOC on its own by setting it at 99% on, 99% off (using local app) but having to wait until it reaches 99% SOC wastes a lot of solar power.

Any ideas on how I change the settings so that the classics switch off my pump as soon as the amps going into the battery bank becomes less than what they would normally need?
