Overview of the Temperature Controller Settings
The basic program settings for each temperature con-
troller satisfy most application needs. 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 settings that are
set before doing an auto-tune or using any controller in
normal operation. See Form 309100 for operation of
the temperature controls.
Graco Factory P, I, and d Settings
Table 2 lists the P, I, and d settings for standard control
panels. These settings are preset at the factory. Use
the table for reference information only.

These P, I, and d values are usually generated by
running 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 tem-
perature.
It is not recommended that “AutoTune” be used for the
heated pump zone.
