able to operators, maintenance crew, supervisors, etc. according
to what function level you want for each group. Security Level C
is not recommended for most users. Gain access to configura-
tion menus using the following codes.

Automatic Reset
Control feature that
automatically corrects for small
temperature offsets that occur
in proportional control. The
higher the setting, the faster the
correction occurs. A high setting
could cause overshoot during
start-up. A low setting will not
allow process temperature
to reach to set point quickly
enough. A setting of “0” turns
off automatic reset. This menu
is active only when the dip
switch is set to “PI”.
