Display Blanking
When Display Blanking is enabled (Y), the display
turns off at the same time the backlight goes off
(after reset, initial power-up, or time-out). When
any button is pressed, the display will reappear
until the time-out is reached again.
Inactivity
The menu/display/backlight time-out (seconds
since the last button is pushed) is set in Inactivity.
Rotation Values
ROTATION VALUES
1:
2: OAT: SHOW
3: CO2: SHOW
4: UI4: HIDE
HUM: SHOW
The Rotation Values menu allows easy setting of
what applicable optional values (e.g., humidity,
outside air temperature, and/or CO
2
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,
the values will rotate approximately every five
seconds.
In applicable models, humidity and CO
2
levels
are shown by default but can be hidden if
desired.
UI4, the fourth rotation value, is available for
custom programming.
Show Temperature Tenths (Decimals)
With R2.0.3.x and later firmware, 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.
This does not affect setpoint adjustments, which
are always in whole degree increments for Fahr-
enheit and half degree increments for Celsius.

A flashing “SERVICE” on the Home screen
indicates an alarm. Built-in alarms are triggered
under these conditions:
•
Space Temp Alarm —temperature outside the
range of 56 to 86° F for over 300 seconds.
• Space Humidity Alarm —humidity above 65%
for over 300 seconds. This is available only
when a dehumidification option is selected in
the Humidity setup). See Humidity Setup on
page 9 .
• Fan Fail Alarm —no fan status signal within
five seconds of call for fan (and Input 2 is
configured for the fan status sensor option).
See Sensor Setup on page 10 .
• CO
2
Alarm —carbon dioxide level has been
above the setpoint (default 1000 ppm—see
Setpoints on page 16 ) or below 250 ppm for over
30 minutes. If the sensor reading is below 250
ppm, the sensor is not working properly—see
(Advanced) CO2 Sensor on page 11 .
