level) will
display on the lower right of the screen (such as
“HUM: 46% RH” shown on the Hospitality Mode
sample screen). Ifmorethanonevalueisshown,

UI4, the fourth rotation value, is available for custom
programming (using BACstage or TotalControl).
To program UI4 to display setpoint, MAT, or other
value, see the Sample Custom Applications section in
the FlexStatApplicationGuide.
Show Temperature Tenths (Decimals)
With R2.0.0.13 and later rmware, Fahrenheit tem-
perature values on the display change in whole
degree increments by default, and Celsius values
change in 0.5° increments. Changing the default No
to Yes will show tenths of a degree values for both
scales. See Display Options on page 5.
This does not aect setpoint adjustments, which are
always in whole degree increments for Fahrenheit
and half degree increments for Celsius.
Show Time and Date
Time and date appear at the top of the display by
default. Seing the value to No, replaces the top line
with a spinning clock icon. See Display Options on
page 5.
Mode
Mode toggles the home screen and other menus
between the default Standard mode and the (more
restricted) Hospitality and Locked UI modes. See
Display Options on page 5.

Hospitalitymode (also known as Mode 2) has
limited menus and is typically used in hotel rooms.
Users typically can change only the setpoint, system
mode, and fan speed. Pushing the Left and Right but-
