OVERVIEW OF OPERATOR INTERFACES
There are two possible methods of viewing and accessing
the user interface. One of these methods is in the form
of a standard Web Browser and the other is an optional
AcuAir® Operator Interface Touch screen.
USING A WEB BROWSER (ETHERNET)
General Description
The Quantum™ LX AcuAir® user interface may be
accessed from any web browser. This feature allows any screen to be viewed from a remote location
without specialized software. An Ethernet connection
to the Quantum™ LX panel must be provided to utilize this feature.
The web browser interface can be viewed from any
desktop or laptop computer, which has access to
the network that the Interface panel is attached to.
Refer to the previous section entitled Connecting A
Computer Directly To A Quantum™ LX Control Panel
when setting up your network.
Setup
On the address bar, type the following [ http:// ].
Do not type the brackets. After the http:// type in
the values of the four boxes from IP Address of the
Ethernet Confi guration screen. Place a period (dot)
between each group of numbers. Using the screen
information example used here, the result would be
http://192.168.0.252. Your particular IP Address may
vary from the example shown.
Press the [Enter] key on your computer keyboard,
and if everything is connected and confi gured prop-
erly, the Home screen of the Interface Panel should
now appear on your computer screen (similar to the
following):
Access the Ethernet Confi guration screen at the In-
terface Panel, by selecting Menu > Confi guration >
Ethernet. The following screen will be shown:
Note the values that are displayed in the four boxes
of the IP Address.
At the computer, open the Internet browser (click on
your Internet icon). Once the browser has opened,
look for the address bar, it will appear similar to the
following:
If you experience problems, such as a message stating “Page not found”, consult with your IT department.
Screen Keys
To change screens, setpoints, etc., you simply use a
mouse and the keyboard to view and change data.
All Interface screens will have several buttons on the
right hand side of the screen:
[Menu] – Clicking on this button will cause the
main menu to appear on the left side of the
screen. Clicking a second time will cause the
menu to disappear.
[Submit] – Although this button does not appear
in the example above, it will be present on most
screens. It is used any time that you have modifi ed a setpoint, or made any change to a screen.
Before leaving that screen, you must press the
[Submit] button for the changes to be saved.

QUANTUM™ LX AcuAir™ CONTROL PANEL
OPERATION
AcuAir® Operator Interface Touch Screen
General Description
This optional user interface has been designed to allow
an operator to effi ciently access, control and monitor the
operation of all Frick AcuAir® units from a single access
point, when all units are connected through a common
Ethernet network. The touch screen control panel is used
for graphic displays. By touching an active area of the display, a data entry box will appear, allowing the operator
to enter different setpoint values, via a keyboard overlay,
that will appear on the screen. The Operator Interface
panel provides a platform to easily navigate between all
networked control systems, as well as a remote access
point which is reachable from any desktop web browser.
Remote access provides users with the ability to connect
to Frick control systems from both home and offi ce, or
any other location providing Internet access.
Touch Screen Calibration
When the panel completes it boot sequence, the user will
be presented with a message box which requests the user
to touch the screen to enter calibration mode. If the user
touches the message box before the 3-second timer expires, the screen will change, presenting the user with
four orange targets. These targets permit the user to calibrate the touch screen’s mouse pointer location. If these
points are not properly set, the mouse pointer will not
appear where the user’s fi nger makes contact with the
screen. Once the screen’s calibration target appear, it is
best to use a dull pointed object to touch each of the four
targets, as a fi nger makes contact with an area too large
to provide accurate calibration.
Browser and Keyboard
Both the browser and keyboard should appear on the
screen once the panel has fi nished its startup sequence.
Each panel is equipped with a program which will restart
the keyboard and browser if either application is closed.
The browser has a small icon in the center of the top tool
bar, which permits the user to return to the panel Home
Page at any time. From the panel Home Page, the Keyboard button can be used to restart the on-screen keyboard should it disappear.
The keyboard can be used to enter text into any fi eld ap-
pearing within a web page. To enter text into a fi eld,
simply touch the desired fi eld in the web browser. If the
fi eld is properly selected, a cursor should appear within
the text fi eld. The user can also drag his/her fi nger over a
segment of text in the fi eld to “select” it. Any key strokes
from the keyboard will then replace the highlighted text.
If the keyboard fails to transmit characters into the desired text fi eld, there could be one of two problems. First,
be sure the text fi eld is selected. Typically the cursor is a
good indicator that focus has shifted to the desired text
fi eld. The second problem involves a keyboard loss of
focus. To resolve this problem, fi rst touch the desired text
fi eld, then touch the [Focus] button on the bottom right-
hand corner of the keyboard, fi nally touch the desired
text fi eld a second time. After this sequence, characters
should be directed to the correct location. This three-step
sequence should be used whenever the keyboard appears
unresponsive.
Keyboard Overlay
Home Page
The panel Home Page displays all the units accessible
through the Operator Interface Panel. Any confi gured
units will appear with an icon and a descriptive label. If an
icon is touched, the web browser will be directed to the
Quantum LX control page. To return to the Operator Interface Panel’s Home Page simply touch the “Home” icon
on the browser’s toolbar.
Admin Home Page
The Operator Interface Panel is equipped with the Admin Home Page to handle various confi guration functions.
This area can be accessed by pressing the Admin button
on the panel’s Home Page. As user name and password
are required to access this area (Username: admin, Password: 2staycold).
Upon entering the admin area, the user will be presented
with the list of all registered units (nothing will be displayed here if no units are registered). If any registered
units are listed, and Edit button at the end of each row
allows the user to change the specifi cations of a specifi c
QUANTUM™ LX AcuAir™ CONTROL PANEL
OPERATION
090.510-O (SEPTEMBER 13)
Page 9
unit. A row of Admin buttons across the top of the page
allow the user to add new units, or delete units from the
list of registered units. Each unit must have a unique
name (no two units can have the same name) and an IP
address (the IP address is not required to be unique, so
more than one link can redirect the user to the same unit).
The user can also select the type of unit which results in
an appropriate icon being displayed on the panel Home
Page where all units are listed.
Network Confi guration
In the Admin area, the Network Confi g button can be se-
lected to modify the Operator Interface Panel’s network
settings. When the page is loaded, the current network
settings are displayed for the user to view. It is possible to
change the IP address, subnet mask, and default gateway.
The IP address type can be static or dynamic; the later option requires a DHCP server to be present. Please consult
a network administrator to modify the values correctly. It
is also possible to specify a network name, allowing access to the Panel from a Windows network.
Finally, the web server port can be changed from the Network Confi guration page. This is traditionally set to 80
which all web browsers understand to be the default port.
If this is changed to any other value, the panel can only be
reached from an external computer by appending the port
number to the IP address (e.g. if the Panel’s IP address
is 192.168.0.5 and the web server port is 400, an external web browser will access the panel through the address: 192.168.0.5:400). If this panel does not need to be
reached from an external computer, then the web server
port setting should be disregarded.
In the event the web server port or IP address settings are
changed, the panel may need to perform a reboot before
these changes take effect. This it will do automatically,
and the user will be notifi ed when this is about to occur.
Resetting the IP Address
In the rare occurrence that a local Air Handler loses Ethernet communications with the Web Browser or Operator
Interface Panel, it could be that the unit has an invalid
IP address. One way that this could happen would be if
the unit has just had a program upgrade, without the setpoints being properly saved then restored (the IP address
is stored as a setpoint to the fl ash card).
In order to correct this situation, perform the following
steps:
1. Power down the failing unit.
2. Locate the processor board (located on the inside of the top door).
3. On the Q4 controller only, locate and temporarily
remove LK12 (on the larger board).
4. Power the unit up.
5. Wait for one minute to allow the processor to
fully boot.
6. Power the unit down.
7. Replace LK12 (on the Q4 only).
8. Power back up. The IP address will be automatically set to 192.168.0.105. This address is
known to work, and should solve the problem.
At this point, the unit should show up at the
Web Browser or Interface panel (HMI). If the
user wishes, they may now go into the HMI and
modify the IP address for the unit in question to
the number that they need it to be, or they may
leave it alone.
If the above steps fail to bring the unit back into the
network, you should check the Ethernet cables, hub or
switch, Quantum™ control board, etc.

QUANTUM™ LX AcuAir™ CONTROL PANEL
OPERATION
SETUP DESCRIPTION
An in depth installation setup is beyond the scope of this guide,
however some basic rules can be observed:
▯ Maintain a total distance of 2000 feet or less between
the Operator Interface Panel, and the very last Remote I/O Panel on any one communications cable
run. As will be explained later, it is possible to have
two separate communications cable runs, depending
upon the total number of Remote I/O Panels. Keep
in mind that neither of these cable runs can exceed
2000 feet in length.
▯ The system is capable of Ethernet communications,
this may be something to consider when placing Interface Panels, as you would want a nearby Ethernet
connection to be available.
▯ Keep all communications wiring in a separate conduit
from control wiring.
▯ When wiring for communications, it is important to
ground only one end of the communications cable.
This ground will be located in the very last Remote
Panel of each communications cable run. If the communications were to be grounded at both ends, then
it would be possible for ground loops to develop,
which could impair communications between panels.
WIRING FOR AC POWER
Interface Panel
The incoming AC power will consist of three 14 AWG
wires (hot, neutral and ground).
▯ Unlatch the two ¼ turn cover latches to the
Interface panel, and open the door.
▯ Inside the enclosure, you will fi nd a power
supply and a terminal strip, as shown here:
• Connect the three incoming AC wires
to the terminal screws as shown previously.
▯ Interface Panels should be located in easy access ar-
eas, and should be mounted at eye level for screen
viewing.
▯ I/O Panels are rated for both indoor and outdoor use.
Although access to the Remote Panels will be rare
after installation and setup, it is still advantageous
to keep them accessible for potential maintenance
situations (reasonable lighting, suffi cient door swing,
etc.).
▯ Install all panels within a convenient distance of a
power source.
• Proceed to the section entitled Checking the AC Power.
QUANTUM™ LX AcuAir™ CONTROL PANEL

090.510-O (SEPTEMBER 13)
Page 13
Remote Panel
As with the Interface panel, the incoming AC power
will consist of three 14 AWG wires (hot, neutral and
ground).
▯ Unlatch the two ¼ turn cover latches to the
Interface panel, and open the door.
▯ Inside the enclosure, you will fi nd a long DIN
rail at the left side of the panel. At the top
of the DIN rail is a terminal strip (if the unit
is equipped with an optional panel heater, there will also be a circuit breaker), as
shown here:
Ground
Hot
Neutral
CHECKING THE AC POWER
Interface Panel
▯ Ensure that the Control Power switch is in the
OFF position.
▯ Energize the 120 Volt circuit at its source.
▯ Using a DVM, measure the voltage at the AC
power terminal strip. Ensure that you read approximately 120 VAC between Hot and Neutral,
and Hot and Ground. There must not be voltage
between Neutral and Ground.
▯ Once the incoming voltage has been verifi ed,
turn the Control Power switch to ON.
▯ On the enclosure door, and watch the Quantum™
LX controller (on the backside of the door). You
should notice various LED’s blinking or fl ashing.
▯ Watch the display on the front of the door. Af-
ter a short period of time, you should notice the
display showing a boot sequence. Various text
messages will be shown as it proceeds with the
boot-up process. When fi nished, a screen similar
to the following image should be visible:
▯ Connect the three incoming AC wires to
the terminal screws shown above.
▯ Notice that there are multiple number 2
terminals, connection may be made to
any of them.
▯ Proceed to the section entitled Check-
ing the AC Power.
▯ If the panel has reached the point of showing the
above screen, the boot process was successful.
Turn OFF the Control Power switch, and Deenergize the 120 Volt circuit at its source.
▯ If the panel does not reach to the point of show-
ing the above screen, then troubleshooting will
be required. Refer to end of this guide entitled
Troubleshooting.

the enclosure will contain two HOA (Hand-Off
Automatic Modules). These modules allow the
technician to override control signals, by manually energizing components. An example of one
of these modules is shown here:
Red, power OFF
tab
er OFF tab, and a black power ON plunger. These
items are located on a circuit breaker for each of
the two HOA modules. Together, they act as the
Control Power switch.
▯ Using a DVM, measure the voltage at the AC
power terminals (1, 2 and PE). Ensure that you
read approximately 120 VAC between Hot and
Neutral, and Hot and Ground. There must not be
voltage between Neutral and Ground.
▯ Once the incoming voltage has been verifi ed,
push in the Black power ON plungers of both
HOA modules.
▯ To the right of the HOA modules are several I/O
boards. There will be at least one Digital board
(recognizable by the plug-in I/O modules), and
one Analog board. Inspect all boards for the
presence of fl ashing, blinking or steadily lit
LED’s. If LED’s are lit on all boards, then power
has been properly applied.
▯ If LED’s are not lit on all boards, then refer to the
section entitled Troubleshooting.
▯ Push each of the Red power OFF tabs down. The
Black power ON plunger should pop up. If the
plunger does not pop up, then the power was
already off. Do this to both HOA modules.
▯ Energize the 120 Volt circuit at its source.

QUANTUM™ LX AcuAir™ CONTROL PANEL
VERIFYING COMMUNICATIONS
The fi rst step in verifying communications is to view what
I/O boards have been detected by the Quantum™ LX Interface Panel. This information will appear on the About
screen, shown here:
Review the information that is shown in the Analog and
Digital Board areas of the screen. Compare what is shown
against what is actually installed.
NOTE: This screen does not update (refresh) automatically. To see any new or different information
that may occur, you must access a different screen,
then come back to this one to see any new data.
Compare what is displayed here with what is actually installed in your system. If a board is physically installed in
a panel, yet does not show up on this screen, then fi nd
the panel that the board is located in, and visually check
the RX and TX LED’s on the board. These LEDs should
be fl ashing. The RX LED will be fl ashing much faster than
the TX LED, but neither should be off completely, as this
indicates a potential wiring problem.
Start by verifying that the boards within the fi rst panel
in the communications line are correctly being detected.
Then move on to the next panel. If the fi rst panel in the
communications daisy chain shows correctly, but there is
a problem with the second panel, then do nothing with
the wiring up to and including the fi rst panel. Inspect in-
stead the last panel for proper communications polarity
and connections. A good indication that you have wires
backwards (reversed) would be that the RX LED is on solid
within the suspect panel. If wiring WAS found to be incorrect, make the correction, and then access the Communications screen by selecting Confi guration from the Main
Menu, then Confi guration, and fi nally Communications.
OPERATION
On the Communications screen shown above, use the
[Tab] key to select Redetect IO Comms and press [Enter].
This will cause the Quantum™ LX controller to reinitiate
all communications with the system. After redetecting IO
Comms, wait about 30 seconds, then access the About
screen once again. If the wiring issue has been corrected,
the questionable I/O board should now be listed, and the
RX/TX LED’s for that board should be fl ashing normally.
When all installed boards have been detected, then the
basic setup is complete. You can now move on to confi g-
uring the system operating parameters.
TROUBLESHOOTING
The following section will help to identify some common
problems that may arise within an ACUair system. Use this
section in conjunction with the 090.510-M (Maintenance)
manual.
1. Quantum™ LX controller does not have any
LED’s lit:
• Check for the presence of 120 VAC power
at the incoming AC terminal strip. (see the
section entitled CHECKING THE AC POWER)
• Check for the presence of proper DC power
to the Quantum™ (refer to the 090.560-M
manual under the section entitled QUANTUM™ LX CONTROL PANEL POWER SUPPLY.
• If the Quantum™ controller has proper DC
voltage applied, then with turn the control
power OFF, remove the program fl ash card,
and recycle the power. If the LED’s do not
start their booting pattern, continue to the
next step.
• Try disconnecting all cables one at a time
(with the exception of the DC power). If the
LED’s start fl ashing normally, then recon-
nect the removed cables one at a time, until
the problem reappears, then troubleshoot
that cable.
• If the DC power to the Quantum™ controller
is normal, and the cables from the previous
step had all been removed without correcting the problem, then the board will need
QUANTUM™ LX AcuAir™ CONTROL PANEL
OPERATION
090.510-O (SEPTEMBER 13)
Page 17
replaced.
2. Quantum™ LX appears to boot normally, but
nothing shows on the display:
• Ensure that the display cable is securely
plugged in at both ends.
• On the Q4 only. verify that jumpers LK3 and
LK4 on the Quantum™ are set properly.
Both links should be set to position B.
• Ensure that the connectors on both ends of
backlight inverter board are plugged in securely. Use caution when checking around
the inverter, as high DC voltage is present
when the control power is ON.
• Shine a fl ashlight onto the display screen
at an angle. If the Quantum™ has properly
booted, you should see some text dimly
shown on the screen. If it appears as though
there IS something being displayed, but it is
not visible, then there is a problem with the
backlight, the inverter, cable or Quantum™.
INITIAL SETUP PROCEDURE
The following is a basic guide to unit setup.
1. Confi guration is performed fi rst. Although there
are four different Confi guration screens, only the
Control Confi guration needs to be setup for unit
operation.
To gain access to Control Confi guration, login to
User Level 2. The following items are setup on
the two Control Confi guration pages:
• Mode Confi guration
• Control Temperature
• Control Source
• Supply Burner
• Heating
• Dehumidifi cation
• Damper
• Exhaust
• Exhaust Control
• Exhaust Fan Run Warning
• Supply Fan
• Room Pressure
• Pre-Coil Override
• Discharge Temperature
• Desiccant Heat Source
• Defrost
• Defrost Initiation
• Air Defrost
• Smoke Detector – Enables or Disables
the input for a Smoke Detector. For failsafe operation, this input is energized
when there is no problem and de-energized on a fault such as a fi re.
• Cooling – Used for temperature control. The liquid valve is open because
the control temperature equals or exceeds the liquid on setpoint. If the suc-
tion valve is not a modulating valve, it is
open during cooling. During cooling, a
modulating valve regulates the suction
valve based on its setpoints.
• Pre-Wheel Cooling
2. Setpoints are established next. Each unit must be
setup to the customer specifi c control features
and options to be used by a unit controller board.
This setup should not need to be changed by operators. Setpoints are intended to be accessed
and modifi ed only by a Factory Representative
or Distributor. Only those setpoints that will be
utilized for unit operation need be set. The following is the list of available setpoint screens:
Temperature
• Cooling
• Supply Burner
• Heating
• Pre-Wheel Cooling
Dehumidifi cation

4. From Security Setup, establish the desired
access rights of the operators.
The panel now provides quick access to the most important
information and controls of the units and their subsystems.
OPERATOR ACCESS
Operator access to this system is through various screens.
A screen is the physical representation of data on the display. Each screen has a title area. The title is descriptive
of the screen. The current date and time is shown in this
title area. The day of the week, Sunday (Sun.) through
Saturday (Sat.) is displayed. The month of the year from
January (Jan.) to December (Dec.) is displayed. The day of
the month from 1 to 31 and the year from 0001 to 9999
is displayed. The time displayed is the current time in 24
hours (military) format. The hours, minutes and seconds
are displayed.
Some screens are for informational purposes only, and
cannot be modifi ed. These screens typically show ana-
log values such as temperature and humidity, which are
strictly functions of an associated sensor, and as such,
cannot be modifi ed. Other screens show setpoint values
which can be changed, in order modify the units operating
characteristics. For easier viewing, related information is
separated into boxes. Sometimes selections are hidden
when that the feature is unavailable.
TO CHANGE SETPOINTS
The setpoints defi ne the operation and limits of each unit.
These setpoints can be change by operators in the fi eld.
These setpoints are stored on the Compact Flash card.
NOTE: Setpoints are not lost after power is interrupted.
However, we suggest that a list of Setpoints be recorded
and stored safely to facilitate reentry, in case there is a
need to return to the original settings.
1. The data entry fi elds are identifi ed by a black box
with a white interior. The data is shown in black
text. When on a screen that has adjustable setpoints, tab to the setpoint box that you wish to
modify (or select it on a web browser).
2. The current value of that setpoint is shown. Use
the keypad to enter the new value. Typing a new
value will completely erase the old value.
3. Press the keypad [ENTER] or [Tab] key to input
the new data in the data entry fi eld and to move
to the next data entry fi eld.
4. If the data entered into the setpoint box is valid,
press the keyboard [ENTER] key. After all the
setpoint changes on this screen have been entered, press the [SUBMIT] button to save the
setpoint changes to memory.
5. If the value is out of bounds, an error message
box displays the proper range of values. Press
the [OK] button to acknowledge the error message. Re-enter a correct value.

ALARM MESSAGE - Warnings and Shutdown messages are
displayed in the lower left corner of the screen. This area will
be blank if there are no current Warnings or Shutdowns.
USER DEFINED OPERATING STATUS
ANALOG READINGS BOX - The following analog input readings are possible. They are shown if they were enabled during
setup:
• Outside Air Temperature
• Discharge Air Temperature
• Outdoor Air Damper
DESCRIPTION: The purpose of this screen is to allow the user
to assign additional analog channels to be more readily viewable. Since the main Operating Status (Home) screen is capable of only showing a limited number of pre-assigned analog
values, it may be desirable for the user to have a method of
viewing additional information that they can select, on a common screen. They may even select values that are already being displayed on the Operating Status screen, as well as values
that are not shown there.
This screen is provided to allow the user to view up to 20 different analog channels of their choosing.
As an example of how this screen works, assume that in addition to the data that is shown on the Operating Status screen,
the user would like to monitor the Outside Air Temperature,
Room Air Humidity and Pre-coil Air Temperature, all on the
same screen (this one). Notice that Outside Air Temperature
and Room Air Humidity are already shown on the Operating
Status (Home) screen, but the Pre-coil Air Temperature is
shown on the Operating Status 2 screen. In order to set this
screen up to show these three values, the user would highlight
the Enable User Defi ned Channel 1 (or whatever channel they
wish to use), by selecting it with the mouse. Once the box is
highlighted, click on it to cause the possible settings for the
channel to appear. Use the mouse to scroll through the list.
When the selection that you want to use has been highlighted,
click on it to select it. Once selected, a value will appear to
the right of the list, which corresponds to the analog value for
that channel.
The following selections may be shown on this screen:
Outside Air Temperature
• Discharge Air Temperature
• Room Air Temperature
• Return Air Temperature
• Pre-Coil Air Temperature
• Coil Air Temperature
• Room Air Humidity
• Room Pressure
• Differential Pressure
• Outside Air Damper
• Coil Temperature 1- 4
• Pre-Wheel Regen Air Temperature
• Post-Wheel Regen Air Temperature
• Wheel Differential Pressure Switch
• Auxiliary Analog 1 - 20
• None

I/O
Status Box
WARNING/SHUTDOWN STATUS BOX - The Warning/
Shutdown Status is displayed below the Mode of Operation status box. This status box is blank with no message
if there are no warnings or shutdowns present.
If a Warning or Shutdown occurs, a message will be
shown, identifying the type of warning or shutdown. The
defi nitions for the two types of messages are as follows:
WARNING - A specifi c warning message will be
shown when a warning is present. A warning is a
condition that requires operator acknowledgement
but allows the Unit to continue to run if it is already
running. A Warning message indicates that a warning
setpoint has been reached, or exceeded.
SHUTDOWN - This specifi c shutdown message will
be shown when a shutdown is present. A shutdown
is a condition that requires an operator to acknowledge, and causes the Unit to shut down. A Shutdown
message indicates that a shutdown setpoint has been
reached, or exceeded.
To clear a Warning or Shutdown, the operator must access the Current Safeties screen, and acknowledge the
Warnings/Shutdowns by pressing the [Clear Safeties] button. If the conditions that originally caused the Warning
or Shutdown have not been corrected, the Warning or
Shutdown will continue to re-occur until the problem has
been identifi ed and corrected.
RUN HOURS – The total number of hours that the Air
Handler has run since the unit was installed.
