Issue with RKL PC4 channels 2 & 3 solved

all of the controllers use a mix of solid state and mechanical relays. Like it says on DA's website, there are advantages to both. mechanical's don't last quite as long as solid states do, due to their moving parts. With this being said, I have been dosing with my pumps on 2 and 3 for 2 days now and have watched them very closely. I don't start dosing until I get home from work so I can make sure everything is running smoothly.
