Tuning will begin and the lower display will flash
“TUNING”. The output will cycle between 0 %
and 50 % (or low output limit). When tuning has
been completed the lower display will again show
“TuneOF”. The Cool tuning parameters are
entered for the second set of PID constants in the
tuning set up group.
