Overview of the Temperature Controller Settings
The basic program settings for each temperature
controller satisfy most application needs. These set-
tings are preset at the factory, but can be changed.
The input type, temperature scale, and over tempera-
ture alarm point are the critical controller settings that
you must check 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 1 lists the P, I, and d settings for standard control
panels. These settings are preset at the factory. See
form# 309100 for accessing these values and use the
table for reference information only.

Pump 4.2 1081 162 480
Gun 2.1 126 19 ALL
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.
