Hazard Identication Messages
CAUTION
Cautions indicate potentially hazardous situations, which can
result in personal injury or equipment damage if not avoided.
WARNING
Warnings indicate potentially hazardous situations, which can
result in property damage, severe personal injury, or death if
not avoided.
DANGER
Dangers indicate a hazardous situation which will result in

NOTICE
Notices give important information concerning a process,
procedure, special handling or equipment attributes.
DANGER
Electric shock hazard. Can cause personal injury or
equipment damage.
This equipment must be properly grounded. Connections and
service to the MicroTech III Chiller Unit Controller must be
performed only by personnel knowledgeable in the operation
of the equipment being controlled.
CAUTION
Static sensitive components. Can cause equipment damage.
Discharge any static electrical charge by touching the bare
metal inside the control panel before performing any service
work. Never unplug cables, circuit board terminal blocks, or
power plugs while power is applied to the panel.
NOTICE
This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance
with this instruction manual, may cause interference to radio
communications. It has been tested and found to comply with
the limits for a Class A digital device, pursuant to part 15 of the
FCC rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment

Operation Modes
Figure 1: Operation Mode Diagram
Normal Mode
In Normal Mode, the display is updated with temperature,
humidity and occupied status (all where applicable) on a set
time cycle.
The display shows temperature in the desired units (as set by
the jumper on the PCA). Depending on the model, the humidity
will be displayed as well. When both of these variables need
to be displayed (temperature, relative humidity) the display will
cycle through the required values at a rate of one change every
three to ve seconds.
Occupied Mode
If the BACnet VAV Actuator is currently in Unoccupied Mode
(Figure 2), pressing the override button (Figure 3) results in
the display showing the word OCCUPIED and the request is
sent to the actuator to override the unoccupied mode. If the
BACnet VAV Actuator does not get overridden and stays in the
unoccupied mode, the display on the sensor reverts back to
the unoccupied symbol as soon as possible.
If the BACnet VAV Actuator is currently in occupied mode,
pressing the override button ashes the word OCCUPIED and
does nothing else. This functionality is intended solely to let the
user know that the button press was recognized.
Figure 2: Unoccupied Icon
Figure 3: Occupied Icon
Setpoint Adjustment Mode
The temperature setpoint is adjusted by using the plus and
minus buttons. The resulting changes in setpoint are shown on
the display in 1.0°F or 0.5°C increments.
The setpoint adjustment will be displayed, and will stay on the
screen 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 the Normal Mode.
Figure 4: Setpoint Icons
Passkey Mode
Insert the passkey into the sensor HMI (Human-Machine
Interface) port to set up all of the user functionality identied in
Settings. For each parameter, use the following sequence:
• Press the occupancy override button to edit the
parameter
• Press the plus/minus buttons to scroll through 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 nished, remove the passkey from the HMI port
carefully. User setting changes will be saved when the
passkey is removed

Settings
Set Pt Disp – determines how the user views the temperature
setpoint adjustment. The default setting is NUMERIC,
displayed in degrees. The user selects between a NUMERIC
and a GRAPHIC setpoint display.
Set Pt Min – determines the minimum temperature setpoint
value. The default setting is 55°F or 12.5°C. The user selects
the minimum setpoint the room unit should request. The
setpoint limit is ultimately dened 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 55°F to the Set Pt Max
value. The adjustment step size is 1°F or 0.5°C.
Set Pt Max – determines the maximum temperature setpoint
value. The default setting is 95°F or 35°C. The user selects the
maximum setpoint the sensor should request. The setpoint limit
is ultimately dened 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 Max to 95°F. The adjustment step is
1°F or 0.5°C.
Disp. Temp? – determines whether the temperature value
should be displayed. The default value is YES.
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
QFA3x80.F types.)
Disp. Occ? – determines whether the occupancy status should
be displayed. The default value is YES, if the device offers
occupancy override capability.
NOTE: This does not enable/disable the Occupancy override
button functionality, just the display of the occupancy
status.
T Cal – allows the user to eld calibrate the temperature
display and output through a bias adjustment. The default
value is +0°F. Adjustments may be made between -5°F and
+5°F, in 0.5°F increments.
RH Cal – allows the user to eld calibrate the humidity display
and output through a bias adjustment. The default value is
+0%. Adjustments may be made between -5% and +5%, in
0.5% increments
Brightness – allows the user to adjust the display brightness.
Allowable values are 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10, with 1
being the dimmest and 10 being the brightest. The default
setting is 5.
Scr. Saver – allows the user to activate/deactivate the display
screen saver. Available options are: NONE, OFF and FADING.
The default value is NONE. If set to NONE, the dispaly
operates at the programmed brightness level without any
interruption.
OFF – The display will turn OFF after 30 seconds. Any button
press 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 second 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
or NO.

Laptop Pass-thru Mode
To communicate with the BACnet VAV Actuator using
Datamate Base, Datamate Advanced, or Microsoft Windows™
Controller Interface Software (WCIS), connect a PC-compatible
cable (see Table 1 on page 2) from a laptop to the
sensor HMI port at the bottom of the room unit. This puts the
room unit in laptop mode, which deactivates all buttons and
shows LAPTOP on the display. In this mode the controller
communicates with the laptop only. The room unit does not
update measured values to the controller while in this mode.
The room unit returns to the Normal Mode once the cable is
disconnected.
Table 2: Error Messages
Message Meaning
No TEC
No communication with BACnet VAV Actuator. This error will
be displayed on the lower right (icon) section of the display,
and the upper portion of the display should continue to
display temperature and humidity values.
NOTE: This error will appear whenever BACnet VAV Actuator
subpoints are not available or the actuator (or its subpoints)
are not responding to commands.
No Sensor
No temperature or humidity sensor detected on the PCA.
This error will be displayed until the error is corrected. This
message might also display if the wrong controller-to-room
unit-cable is used or if the replacement sensor element is
incorrectly installed on the PCA.
00x
Room unit rmware revision. This is visible upon power-up
for a few seconds until communication is established with the
BACnet VAV Actuator.
Set-up of Displayed Temperature Units
The factory default for displayed temperature units is °F. To
change the display to °C mode, snip the wire jumper on the
back of the PCB (the visible side when the unit is taken off the
wall).
