I want to add an ozonater to the above but need a little help. The model number is LB501S and I have the following info on the inside cover of the controller.
I/O configuration
Ozon & Circ Pump
120v From To
W12 J16
J2 J16
J4 J61
I am assuming that is setting the voltage for the circulation pump and ozonater to 120v or 240v. Does this sound correct. I have a small board at the bottom of the controller that has connectors J6 & J7 on it. J6 goes to the circulation pump and J7 is directly behind it (see photo). I think that J7 is for the ozonater. Is there anyway to tell if this is correct? This information is also on the inside of the cover.

Basic Connector Diagram
1 Top flat on left
2 Unused or pump low
3 Voltage select
4 Ground

I have also included a pic of the label on the unit. Any help would be appreciated.
Thanks
Dan
