If the display screen is not touched in 30s the screen will dim. The screen will go to sleep after 2 minutes of no operation. Touching
the screen will "wake" up the controller again. If the units selected is deg F, the date and time will be displayed as MM/DD/YY, Hr/Min/
Wk. If the units selected is deg C, the display date and time will be displayed as DD/MM/YYY and Hr/Min/Wk.
Power on Display Window
The display will show controller and display versions after several seconds at start up. The top number, after the upper-case V, is
the Control Software version, the bottom number, after the lower-case v, is the Display Software version. These will be displayed for
about four seconds, then show the Home Screen.
If communication fails, the version numbers won’t be displayed and the Home Screen will appear after 15s. In this case, the home
screen will show all zeros, or inaccurate default values.
