Parameters Values
Manually
To change a tuning parameter value
manually:
1. Put the controller in standby by
pressing the MODE key until the
STANDBY LED is lit.
2. Access the tuning menu by pressing
and holding the DISPLAY key until
Pid is displayed on the top line
(approximately 3 seconds).
3. Display the first parameter in the
menu by pressing the MODE key.
The second line of the display will
show Pb (proportional band), the
name of the first parameter in the
menu, alternating with the current
value.

pb with 24
4. If this is not the parameter you want
to change, press MODE repeatedly
until you see the parameter you want.
5. Use the ▼ and keys to change a
numeric value or scroll through the
choices.
6. When the desired choice or numeric
value is on display, press the MODE
key once. The displayed choice or
value will be written to the controller’s
database. The next parameter in the
menu (or the first parameter if you
were at the end of the menu) will be
displayed.
At this point you can:
• change the value of the newly dis
played parameter with the and
▼ keys, or
• if you like the current value of the
parameter on display, you can press
the MODE key to leave the displayed
value unchanged and go on through
the parameters in the menu, or
• exit the
Pid menu by pressing and
holding the DISPLAY key until the
normal operating display returns to
view, and then press MODE to return
to normal mode.
If you do not press any key, eventually you
will be timed out of the Pid menu. The
controller will revert to the operational
display that was in view before you
entered the menu. The value that was on
displa
y when you were timed out of the
menu will be saved to the controller’s
database automatically.
