page shows a summary view of the flow, starting with today’s data. Pressing the
DOWN or UP arrows will scroll to previous day’s data. Up to 365 days will be
stored. Newer data will overwrite the oldest, automatically, once the 365 day limit
is reached. Press RIGHT, CHECK, or POWER to return to the Main Display.

Main Menu for programming.
Pressing RIGHT from the Main Display will take you to the Password pop-out
screen if the factory default Set Password parameter in the Special Functions
menu was changed from 0000. If a password is required, the cursor will
automatically be flashing on the leftmost numeral. Press either UP or DOWN to
change the selection of that numeral, and RIGHT or LEFT to change the flashing
cursor position. Press the CHECK button to accept the password and proceed to
