I don't think that's right, and not what I'm seeing here. What I'm seeing is that in cold water, in normal operation or after a manual addition, the IpH displays the count down to the next injection, regardless if that latest injection attempt failed or not. All subsequent scheduled injections would still be attempted. And this actually makes sense. The IpH continues to schedule its injections, regardless of what just transpired, presumably to resume injections should the offending error correct itself. Cold water would take a while, because the IC doesn't test that but a couple times a day. But if the water did eventually get warmer, eventually the IpH would resume (as would the IC). Another example, the IpH would skip a scheduled injection due to low flow, as it should, but if a minute later the low flow corrects itself, then the next injection will occur correctly, as scheduled. So in that regard, the Pentair engineers have it right.Jim - If you add manually, and the IC cell is up and running, the manual addition resets the timer but the ipH will continue additions every 60 minutes. If you add manually and the IC cell is cold water or low salt cutoff, the ipH will not continue on its normal time cycle as it has been halted by the low cutoffs on the IC cell. I think I explained that clearly. If not, let me know.
