Operation
Operation modes
Figure 1. Operation Modes.
Normal Mode
In Normal Mode, the display is updated with
temperature and humidity, (where applicable) on a set
time cycle.
The display shows temperature in units of degrees
Fahrenheit, or in degrees Celsius if the jumper (resistor
R64) on the printed circuit assembly (PCA) is clipped
(See Setup of Displayed Temperature Units).
Depending on the model, the humidity is displayed as
well. When both of these variables must be displayed
(temperature and relative humidity) the display will
cycle through the required values at a rate of one
change every three to five seconds.
Override
These room units provide a dry contact closure
function, which may be used to signal the controller to
change the night setback or occupancy state. The
contact is made by pressing the override button (button
designated by an image of a man inside a house).
When the button is pressed, the word OVERRIDE
appears in the display. After three seconds, the text
disappears.

Setpoint Adjustment
The temperature setpoint is adjusted by using the plus
and minus buttons. The resulting changes in setpoint
are displayed on the display in 1.0°F or 0.5°C
increments.
The setpoint adjustment will display for three seconds.
If during those three seconds a setpoint button is
pressed again, the setpoint will be adjusted accordingly
and be displayed, and the three-second countdown will
restart. If there is no user input for more than three
seconds, the room unit will return to Normal Mode.
Setup Mode
Press the plus (+) and minus (-) buttons on the device
simultaneously to access the setup mode, and setup all
of the user functionality listed below. For each
parameter, use the following sequence:
•Press the override button to advance to the next
setup parameter.
•Press the plus/minus buttons to scroll through or
toggle the various options available for each
parameter to display the desired option.
•Press the occupancy override button again to
move to the next user-adjustable parameter.
•When finished, press the plus (+) and minus (-)
buttons on the device simultaneously to exit the
setup mode. User setting changes will be saved.
The device will also save changes and exit the
setup mode automatically if no buttons are pressed
for 15 seconds.
Settings
•Set Pt Disp - determines how the user views the
temperature setpoint adjustment. The default setting
is NUMERIC, and displays in degrees. The user can
select between a NUMERIC and a GRAPHIC
setpoint display.
•Set Pt Min - determines the minimum temperature
setpoint value that may be adjusted by the
occupant. The default setting is 55°F (13°C). The
user selects the minimum setpoint the room unit
should request. The setpoint limit is ultimately
defined in the controller. If the setpoint is displayed
graphically as a sliding bar, this sets the left end of
the slider bar. The limits are 55°F (13°C) to the Set
Pt Max value. The adjustment step size is 1°F
(0.5°C).
•Set Pt Max - determines the maximum temperature
setpoint value that may be adjusted by the
occupant. The default setting is 95°F (35°C). The
user selects the maximum setpoint the sensor
should request. The setpoint limit is ultimately
defined in the controller. If the setpoint is displayed
graphically as a sliding bar, this sets the right end of
the slider bar. The limits are Set Pt Min to 95°F
(35°C). The adjustment step size is 1°F (0.5°C).
•Output Range -determines the temperature span
over the selected voltage or current output range.
Temperature range options are as follows:
32°F to 122°F (0°C to 50°C if in Celsius mode)
55°F to 95°F (13°C to 35°C if in Celsius mode)
40°F to 90°F (4°C to 32°C if in Celsius mode)
The default range is 32°F to 122°F (0°C to 50°C if in
Celsius mode)
•Disp RH? - determines whether the humidity value
should be displayed. The default value is YES, if the
device is a humidity room unit. (This option is
conditional based on the presence of humidity
measurement capability, and only offered with
QFA3xxx.F types.)
•T Cal - allows the user to field calibrate the
temperature display and output through a bias
adjustment. The default value is + 0°F (0°C).
Adjustments can be made between -5°F (-3°C) and
+ 5°F (+3°C), in 0.5°F (1°C) increments.

•Disp Temp? - determines whether the temperature
value should be displayed. The default value is YES.
•RH Cal - allows the user to field calibrate the
humidity display and output through a bias
adjustment. The default value is + 0%. Adjustments
can be made between -5% and + 5%, in 0.5%
increments
•Brightness - allows the user to adjust the display
brightness. Valid values are 1, 2, 3, 4, 5, 6, 7, 8, 9
and 10, with 1 being dimmest and 10 being
brightest. The default setting is 5.
•Scr Saver - allows the user to activate or deactivate
the display screen saver. Available options are:
NONE, OFF, and FADING. The default value is
NONE.
−NONE - The display operates at the
programmed brightness level without any
interruption.
−Off – The display will turn off after 30 seconds.
Any button that the user presses will wake it up
(without doing anything else), and then the
device will operate in Normal Mode for 30
seconds until the display turns off again.
−Fading – Within 30 seconds of no operator
interaction, the entire display will fade to a
display brightness of 1. The display will operate
at this brightness until the user presses a
button. At that time, the programmed display
brightness will be restored.
•Factory Defaults - allows the user to reset all
parameters to factory defaults. Available options for
this parameter are YES and NO. The default setting
is NO.

Error Messages
Message Meaning
NO
SENSOR No temperature or humidity sensor
detected on the PCA. This error will
display until it is corrected. Either the
sensing element should be replaced
(where possible) or the device should
be replaced. This error may also
display if the cable is miswired
between controller and the room unit or
if the replacement sensor element is
incorrectly installed on the PCA.
0xx Room unit firmware revision is visible
for five seconds upon power-up.
Set-up of Displayed Temperature
Units
The factory default for displayed temperature units is
°F. To change the display to °C, snip the wire jumper
(0 Ohm resistor R64) on the back of the PCA (the
visible side when the unit is taken off the wall).

1. If the device has a switch, determine if voltage or
current output is needed.
•For current, set the switch in the down position
(I).
•For voltage, set the switch in the up position
(V).
2. If selecting voltage, set the jumper as follows:
•Use the top and middle pins for 0 to 5V.
•Use the bottom and middle pins for 0 to 10V.
