My T-15 cell is nearing it's end of life, and to maximize it's potential, I tried switching the cell type from T-15 to T-9 on my OmniLogic controller. When I did this, the PPM increased by about 400, however on the Aquarite diagnostic display it's still showing T-15. I'm not sure if I should attempt to change the cell type on the Aquarite itself, I'm a little worried that I'll somehow get it out of remote mode if I try to do that. FWIW, the Aquarite does show the output that I have set in my OmniLogic.
