Set Point, on the bottom display.
Error messages may over-ride the HOME display. See ERROR MESSAGES on

display will return to the HOME position displaying the process value. While in the
Secure Menu, if no key is pressed for a period of 60 seconds, the display will return
to the HOME position displaying the process value. Outputs are disabled (turned
off) when the Secure Menu is active.
