Title: Error in Classic Manual about AUX 1
Post by: ClassicCrazy on May 09, 2020, 01:19:22 AM
The Classic Manual says this for AUX 1
SOC % High
When SOC reaches % LOW, AUX 1 will turn ON. As the SOC goes up and reaches % HIGH, AUX 1 will turn OFF.


I believe it should say
SOC % High
When SOC reaches % HIGH , AUX 1 will turn ON. As the SOC goes down and reaches % LOW , AUX 1 will turn OFF. 

That is usually what I use - and if I set it for 98% Off and 99% On then I know the loads will never run my battery down below 98 %

I will have to check the SOC Low  - I don't use that but I think it is worded opposite so it might be wrong too.

Also Aux 2 Float High seems to me that it is doing PWM to hold the Float Voltage . It doesn't say this in the manual. I will check it again tomorrow . I have been experimenting with it today and tried a lot of different settings but pretty sure I saw it varying the load . I have Aux 2 controlling SSR that controls 120 AC  outlet that I have water heater plugged into .

Or could it be that when I was around the Float voltage it was just turning the Aux2  on and off real fast because it was late afternoon ?

I am playing around with the Waste Not High now - seems to be working as the manual says - once I figured out that I just needed to set the voltage to 1 volt instead of 30 . I am seeing it adjust the load via pwm so that it maintains the battery voltage  above the Absorb or Float setpoint .
