Overview of the Temperature
Controller Settings
The basic program settings for each temperature con-
troller satisfy most application needs. The defaults are
for using a hose on zones 1 and 3, and a gun on zones 2
and 4. These settings are preset at the factory, but can
be changed. The input type, temperature scale, and over
temperature alarm point are the critical controller set-
tings that are set before doing an auto- tune or using any
controller in normal operation. See Form 309100 for
operation of the temperature controls.

Table 5 lists the P, I, and d settings for standard control
panels. These settings are preset at the factory. Use the

These P, I, and d values are usually generated by run-
ning an autotune process for each heat zone. The
controllers will automatically find the proper P (propor-
tional), I (integral), and d (derivative) values during
this autotune process. These are values that allow the
heat zones to reach their maximum temperature as
fast as possible without significantly exceeding
desired temperature.
