Heaters for 4-Zone Control Panels
Temperature Controller Settings
The basic program settings for each temperature con-
troller meet the needs of most applications and are pre-
set at the factory.
The input type, temperature scale, and over temperature
alarm point are the critical controller settings that you
must check before doing an auto-tune or using any con-
troller in normal operation. See manual 309100 for oper-
ation of the temperature controls.
Graco Factory P, I, and d Settings
The table lists the P (proportional), I (integral), and d
(derivative) settings for standard control panels. These
settings are preset at the factory. Use the table for refer-
ence information only. See manual 309100 to assess
these values.
Graco Factory P, I, and d Settings
The P, I, and d values are usually generated by running
an auto-tune process for each heat zone. The control-
lers automatically find the proper P, I, and d values dur-
ing this auto-tune process. The values are selected to
allow the heat zones to reach their maximum tempera-
ture as fast as possible without significantly exceeding
desired temperature.
