Adaptive Tuning
Adaptive tuning continuously evaluates tuning parame-
ters. Adaptive tuning automatically installs new values if
better accuracy is possible. Adaptive tuning should be
used when the characteristics of a process change due to
load or setpoint changes or, in a process that can not
handle the oscillation caused by a one-shot tune.
To tune your furnace using adaptive tuning:
1.
Load your furnace with a load characteristic of
those you intend to heat in it.
2. Press the PAGE button until display reads, “Atun
LiSt.”
3.
Press the SCROLL button until “drA OFF” is
displayed.
4. Press the UP or DOWN button to select “on.”
