– Time Actual: this parameter shows the measured time in seconds for the
current draw to decrease across predetermined thresholds during the last
evaporation cycle.
– Current Relative: this parameter shows the present percentage of cur-
rent draw (amps) being observed for the cylinder relative to the current
required to satisfy the demand.
– Drain P: this parameter shows the proportional drain time calculated based
upon the last boil down cycle.
– Drain I: this parameter shows the integral drain time calculated based
upon the trended boil down cycles.
– Drain Time: this parameter shows the time calculated for the last demin-
eralization drain.
– Drain Sum: this parameter shows the sum of the proportional drain time,
integral drain time, and drain time accumulator that results in a total time
for the next demineralization drain.
