underneath “MENU” to enter the Main Menu.

(see UIM Navigation on page 48)

Notice how the text above the Operational Buttons on 
the display changes as you navigate through the various 
menus and screens.

With Temperatures selected (highlight in black) in the 
Main Menu, press the Operational Button underneath 
“SELECT” to enter the Temperatures Menu.

for this menu item.

Press the Up and Down buttons to adjust the Operating 
Set Point to the desired setting.

Press the Operational Button underneath “UPDATE” to 
confirm the new setting. Press the Operational Button 
underneath “CANCEL” to discard the new setting and 
retain the previous setting.

The new Operating Set Point value should now be 
displayed as the current value.

settings and the Tank Probe Offset in the Temperatures 
Menu. 

This same procedure is used to change user settings in 
other control system menus.
