A:Answer Hi there!
The default temperature setting is 54° F (12° C), and the default temperature scale is ° F.
When the up or down buttons are pressed, the temperature increases or decreases in increments of one degree.
To switch the display between F° and C°, press and hold the up and down buttons at the same time for approximately three to five seconds.
