Manual Program Advance Button
IMPORTANT: To prevent damage to the

30-minute period before or after a program
change.
The manual program advance button enables
immediate, one-time-only program changes to
accommodate temporary schedule changes.
Press the button to immediately begin an
energy savings period or return to the normal
setting. After pressing the button, check the
program indicator to ensure the system is in the
desired mode. If the program indicator shows
blue, the lower temperature is in effect; if it shows
red, the higher temperature is in effect. Using the
manual advance button will not affect the stored
program.
