I. UNCRATING
Carefully examine the carton(s) for damage. If the carton
is damaged, immediately notify the shipping company. Do
not delay in ling claim. If the air door(s) were shipped on
wooden skids, remove protective wood and banding straps securing the carton(s) to the skid. Open the carton(s) and remove
all protective packaging. Immediately verify that the electrical
rating nameplate located on the cover matches electrical power
supply available. Retain the shipping carton(s) until the air
door(s) are installed and properly operating.
ACCESSORIES: If the air door(s) were ordered with optional
electrical accessories, the accessories will be found in the carton
containing the air door or in a separate carton(s) accompanying the air door(s). Check all of the cartons/skids for accessories
before discarding.
II. MOUNTING PREPARATION
INDOOR MOUNTING ONLY - Environmental/Insect/Dust Control
A. The In-Ceiling Mount air curtain is designed to be an ef-
fective barrier against cold drafts in the winter and hot air
in the summer. To achieve optimum protection, the unit
should be mounted on the inside of the building, ush with
the ceiling, so that the airstream can pass as close to the
top of the door opening as possible. To ensure peak performance keep the air stream free of obstructions.
B. The air door will not perform properly if negative air
pressure exists in the building. Under these conditions,
a means for makeup air to the building must be provided so that the air pressure on both sides of the opening
is in balance.
C. Before mounting the air door, check the supporting struc-
ture to verify that it has sucient load-carrying capacity to
support the weight of the unit(s). The mounting hardware
(supplied by others) should be capable of supporting a
minimum of three (3) times the weight of the unit. See
Table 1.
D. When determining the mounting location for the unit(s),
make sure that nothing interferes with the curtain of air

For Master/Slave operation, a serial cable connection must be
made between the Intelliswitch® control boards of each air door
to be linked.
1. Disconnect power to all the air doors
2. Find the (RS485) phone jack couplers protruding through
the hole in the endplate next to the j-box.
3. The serial cable ordered for each air door will be coiled up
and attached to the left endplate.
NOTE: There will be one less serial cable than the number of
air doors ordered. E.g. Two air doors together will need only
one cable; three air doors together will need two cables,
etc. Any extra cables can be kept as spares.
V. FIELD CONNECTIONS
A. ELECTRICALLY HEATED MODELS
The heater circuit may be controlled by a remote thermo-
stat or manually through the Intelliswitch® located on the
discharge side of the air door. Overheating protection is
provided by auto reset thermal cutouts built into the heater
coil assembly (see the wiring diagram).
B. STEAM AND HOT WATER HEATED MODELS
Piping should be done in accordance with local codes,
regulations and standard practices. Connect the building
system supply and return to the ¾” MPT nipples on the
heating coil. See Figure 4.
4. Plug the (RS485) male phone jack on the end of the serial
cable into the empty coupler on the next air door.
5. Continue process for all air doors that are to be connected
serially.
6. Serial cable connections are capable of two way communication. It does not matter to which coupler the cables are
connected.
7. The rst and last air door in the group will each have an
empty coupler after all connections are made. If there are
only two air doors connected, each will have an empty
cable coupler.
NOTE: If a longer cable is required than was supplied, it can
be ordered from the factory or made by using standard 4
wire at telephone cable, phone jack connectors and the
proper crimping tool.
G. Remote Mounted Display Faceplate – If operation of the
Intelliswitch® is to be through a Factory Ordered Remote
Mounted Display Faceplate, continue, otherwise, skip to
step H.
NOTE: Maximum mounting distance between the Display
Faceplate and the air door is 20’.
1. When the remote faceplate option is ordered from the
factory, the air door comes equipped with the blank
faceplate already installed and the 20’ ribbon cable attached. The Display Faceplate is shipped loose, ready
for eld installation.
2. Locate the male end of the conductor ribbon cable
and run it to the remote display location. The cable
is minimum CL2 rated and should not need to be in
conduit.
3. Connect the female end of the ribbon cable to the
14-pin socket on the back of the display board with
the cable approaching from the top and the red ribbon
indicator to the right (when facing the front of the

INTELLISWITCH® FAQ’s (Frequently Asked Questions)
www.intelli-how2.com
WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
Before servicing or cleaning unit, switch power o at service panel and lock the service disconnecting means to
prevent power from being switched on accidentally. When the service disconnecting means cannot be locked,
securely fasten a prominent warning device, such as a tag, to the service panel.
Even though every In-Ceiling Mount unit is individually tested at the factory before shipment,
on occasion improper functionality may be experienced. Here is a list of common questions:
Q. Why can’t I change my settings?
A. The Intelliswitch® may be locked. If the Lock light is illuminated, the control is locked. To unlock, press and hold the left &
right arrows simultaneously for 5 seconds. The Lock mode can
also be protected with a PASScode. If the PASScode option is
on, an attempt to unlock the control will display PASS and then
a 0000 prompt. A four-digit code (available in the installation
instruction book Appendix) must then be entered to unlock
the control. Use the up and down arrows to select a number
and the left and right arrows to select the digit to edit. Press OK
when done. Note: If the AutoLock setting is on, the control will
re-lock if there is no activity after 5 minutes.
Q. Why won’t my heat work, even though fans are running?
A. The thermostat(s) or speed sensor may need adjusted or
replaced.
1.) Make sure that the thermostat probe and/or remote thermostat are in the “On” position and set above ambient (room)
temperature.
2.) Check internal and external thermostat status in the Diagnostics Menu for a faulty thermostat. To do this, hold the right
arrow for ve seconds until DIAG appears, then arrow down to
the ts setting, if it displays “1” then the thermostat(s) is working
(there is a call for heat).
3.) If no external thermostat is used, check to see if the internal
probe is attached to the control board. Disconnect power to
the unit, remove the display board and check that the beige
sheathed cable is attached at both ends. If the thermostat(s)
and settings are correct and you are still not getting heat, then
check to see the fan speed. to do this, press the down arrow to
reach the Mode/Fan speed setting. Use the right and left arrow
to change the fan speed.
4.) Check to see if you can adjust the fan speed. If the speed
sensor is bad there will be no speed control and the Intelliswitch® will not let the heat come on. If it is too dicult to determine a change in speed, the speed sensor can be checked by
entering the DIAG menu and checking the rst error code. If ER
10 displays, the speed sensor is recognized by the Intelliswitch®.
If the code ER 11 is displayed, the Intelliswitch® does not recognize the sensor, and it may be faulty or need adjusted closer to
the trigger bar. Turn o the power to the unit and remove the
screen to check the distance between the sensor and the trigger located on the left side of the motor (use the bottom access
cover for steam/hot water heated units). The sensor should be
less than 1/16” from the trigger face. Check distance at both
ends of trigger. Adjust if necessary.
5.) If there is still no heat or speed control, you may need a new
speed sensor: consult factory.
Q. Why won’t the Intelliswitch® light up?
A. There may not be power to the control.
1.) Check to see if the main power is turned on to the unit. Your
air curtain may have multiple disconnects, be sure all are turned
on.
2.) Verify that there is power to the board. NOTE: ONLY QUAIL-
IFED PERSONS SHALL CHECK POWER IN THE UNIT WITH THE
POWER ON. The power terminals are located directly behind
the display. Remove two Phillips screws from the Intelliswitch®
display to expose the power terminals and check the line voltage at spade terminals L2 and 120, 208 or 240 (depending on
the voltage supplied to the unit).
3.) Check the ribbon cable connections to the display board for
a loose connector or improperly connected cable (see Installation Instructions for correct cable connection).
4.) If there is line voltage power at the board terminals, the ribbon cable is correctly connected, and it is still not working, you
may need a new circuit board: consult factory.
5.) If there is line voltage power at the board terminals, the
ribbon cable is correctly connected, the speed sensor and the
thermostat are working, and it is still not working, you may
need a new circuit board: consult factory.
Q. Why won’t my fans shut o?
A. The Intelliswitch® may be in the wrong mode or mis-wired.
1.) Check to see if the control is in the “ON” mode, if it is, then
change the Mode to another setting.
2.) The T-Stat Mode may be set to the “both” setting and the
thermostat is calling for both Fan and Heat, change the T-Stat
Mode to “HEAT”.
3.) If there is a door switch and the unit is in a mode that is activated by it, there could be a short, mis-wiring or mixup in components. Close the door and check the door switch status in the
Diagnostics menu. Hold the right arrow for ve seconds until
DIAG appears, then arrow down to the ds setting, if it displays
“1” then the door switch signal is closed (there is a call for fan). If
the door is closed, the signal should be “0” or open.
4.) There could be a short in the eld connections to the door
switch or the door switch leads could be mis-wired. To test,
disconnect the door switch connection at the unit. Opening the
wiring tray on top of the unit and be cautious of high voltage
connections. Disconnect the blue wires labeled 9 & 10 from the
eld wiring to the door switch or make sure they are not tied
together. There is no danger of getting shocked because the
signal is 5 volt dc. Be sure not to touch the blue wires to anything metal (or grounded). The unit should shut o when it is in
any mode that is activated by the door switch.
5.) If the air curtain is heated, make sure that the thermostat
isn’t wired to the door switch leads. Door switch leads are blue

INTELLISWITCH® FAQ’s Continued (Frequently Asked Questions)
www.intelli-how2.com
Q. How can I check the door switch to be sure it’s working?
A. The Intelliswitch® may be in the wrong mode, be mis-wired
or have a faulty door switch.
1.) Test the wiring and controller function at the same time rst.
Locate the door switch and open its wiring compartment by removing the two screws holding on the back cover. There should
be two wires connected to screws inside the switch. There is no
danger of getting shocked because the signal is 5 volt dc. Be
sure not to touch the wires to anything metal (or grounded).
Either disconnect both wires from the screws (noting which
screws the wires are under) and touch them together (with air
curtain in “Auto” mode) or make a short jumper wire and touch
the jumper to both screws at the same time to see if air curtain
comes on. If it does, the controller and wiring work.
2.) If the wiring and unit pass the function test, the problem
could be either misalignment or a faulty door switch. On a
magnetic reed switch check for magnet alignment, for plunger/
roller type switch, check contact engagement with door.
3.) If you have access to an electrical test meter, the door switch
contacts can be tested for continuity when the door switch
wires are disconnected from the unit.
Q. Why won’t my heat shut o?
A. The Intelliswitch® may need adjusted, have been mis-wired
or have a faulty thermostat.
1.) Heat is activated by one of two thermostat connections.
To test the internal thermostat set the external thermostat to
OFF. The settings of the unit mounted thermostat probe are
accessed through the display. Press the down arrow until the
Temp Set indicator lights up; check if the temperature setting
and unit of measure are correct. Test to see if it shuts o by setting the thermostat temperature to OFF or lower than the room
temperature.
2.) If an external thermostat is connected to the unit, there
could be a short in the eld connections or the thermostat
leads may be mis-wired. To test the external thermostat set the
internal thermostat to OFF. Disconnect the external thermostat
connections at the unit. Open the wiring tray on top of the unit
and be cautious of high voltage connections. Disconnect the
orange wires labeled 6 & 7 from the eld wiring to the thermostat or make sure they are not tied together. There is no danger
of getting shocked because the signal is 5 volt dc. Be sure not
to touch the orange wires to anything metal (or grounded). The
heat should shut o when the wires are separated.
For more complex troubleshooting of either thermal cutouts or
heater contactors, please consult a qualied electrician or the
factory.
Q. Why didn’t the Intelliswitch® save the changes I made to
a program?
A. If a program is active (a dot is illuminated by one of the
clock digits), changes can be made to any settings on the User
Menu. These changes however will only remain in eect until
the program changes to the next time zone. To make changes
permanent, settings must be changed in the program from the
Program Menu. Access the Program Menu by holding down the
left arrow for 5 seconds until “PRO” is displayed. Arrow down
to select programming and arrow left to select the program to
edit. Use the down arrow to step through the options and make
changes as desired. Continue to press the down arrow until Stor
is displayed. Press OK or down to keep or store the changes.
Q. How do I undo a change that I made to a program in the
Program Menu?
A. Changes to programs cannot be undone. The programs can
however be reset to the factory default settings. This must be
done on the Factory Menu. Access to the Factory Menu is attained through the Diagnostics Menu. Press and hold the right
arrow for 5 seconds until “DIAG” is displayed. From the “DIAG”
display press and hold the up and down simultaneously for 10
seconds until “FACT” is displayed. Use the down arrow to select
“DEFn” on the display then use the right arrow to select “DEFP”.
Press “OK” to reset. The control display will go blank then blink
as conrmation.
Q. My air curtain won’t turn on?
A. Check the AM/PM setting on the Start and Stop times or the
clock (considering the AM indicator light whensetting values).
Note: set the start time and stop time to the exact time for the
unit to be active full time. Check to see if a program is active
that may have dierent start/stop times than those expected.
Q. My building has a Building Management System, can the
Intelliswitch® work with a BMS?
A. The Intelliswitch® can be controlled by a Building Manage-
ment System (BMS) but currently does not have the ability to
communicate with them. Dry contacts on the BMS may be used
to control the unit activation through the door switch connections (blue wires 9 & 10) and the heat activation thought the
remote thermostat connections (orange wires 6 & 7). Consult
factory.

troubleshooting. The status of 1-4 can be observed from the
Diagnostic Menu. The format for displaying the error code is the
“Er” descriptor and a two digit code. The rst digit is the error
number and the second digit is the status using international
convention. 0 = inactive, 1 = on or active.
6.11.1. Error Code 1 – Speed Sensor
Er 10 – Prox Sensor or Speed feedback exists
Er 11 – NO Prox Sensor or Speed feedback
Solution – check to see if the proximity sensor (located next
to the motor) is connected to the control board and check
distance between tip and trigger bar is approximately 1/16 of
an inch.
6.11.2. Error Code 2 – Line Frequency
Er 20 – power supply line frequency exists
Er 21 – undetermined supply line frequency
Solution – The Intelliswitch® automatically senses line frequency. In the event that it can not determine the proper line
frequency, it will run at full speed and ash error. Manually set
the line frequency in the FACT menu. See Section 7.5.
6.11.3. Error Code 3 – Zero Cross/Power Issues
Er 30 – clean power exists
Er 31 – poor power exists, electrical noise
Solution – When the control encounters “noise” in the electrical
power supply it will run at full speed and ash error code. There
are no internal changes available. Have the electrical system
checked for problems.
6.11.4. Error Code 4 – Speed Feedback
Er 40 – proper motor and sensor operation
Er 41 – Motor o but receiving prox/speed sensor feedback
Solution – this is usually the result of a failing motor control
component on board that cannot be serviced. A replacement
board is required.
6.11.5. Error Code 5 – Corrupted Memory Setting
Er 51 – Status of this error is not available. It only appears when
there has been an event that has corrupted the settings in
memory. When corrupted settings are identied the control
6.11.6. Error Code 6 – Incompatible Speed Range for Master/Slave Operation
Er 61 – Status of this error is not available. It only appears when
unit are connected in a Master/Slave conguration that do not
have identical Speed Range settings.
If two units are connected without equivalent speed ranges,
every time a button is pressed on the Master unit (the unit used
to make setting selections) the Slave unit will display an “Er 61”
and the Slave will ignore the command to protect the control
from damaging the motor.
Solution – Enter the Factory Menu to select the proper Speed
Range (See Sections 7 and 7.1)
Note: This error does not monitor if the correct speed range
has been selected for a Series/Model. Only that two or more
units have been connected that do not have equivalent
speed ranges.
Note: Once the correct speed ranges are selected and the
controls accept commands from one another, the controls
should be synchronized by simply cycling through all of the
settings on the User Menu using the up or down arrows.

a low 5 volt DC voltage signal to monitor contact closure.
If the internal thermostat is left on, the external heat mode
will operate in parallel to contact closure, allowing either one
to activate the heat. If the internal thermostat is turned o the
external heat mode will activate independently to activate the
heat.
8.2.1. External Thermostat
An external (remote) thermostat connection can be used to
sense temperature independent of the built-in thermostat. Connect thermostat to terminals 6 and 7 in the unit junction box.
8.2.2. Building Management System
A building management system or dry contact closure can
be used to activate the Heat Mode for all Operating Modes.
Connect applicable contacts to terminals 6 and 7 in the unit
junction box.
8.3. Master/Slave Operation
For Master/Slave Operation a serial cable connection must be
made between all Intelliswitch® controls of each unit to be
linked.
Once units are linked all Menu settings made through any unit
display or remote control will transfer to all other linked units.
Parameter changes made on any linked unit will update all
other boards “live” upon menu selections.
9. Infra-red Remote Control
The handheld infra-red remote control buttons layout and
operation are the same as that on the Intelliswitch® unit display
(including multiple button presses) with one exception, the
Lock Button.
There is no need for multi-button press and hold for lock/unlock
activation. The Lock button will lock/unlock display in one press.
NOTE: AutoLock, Comfort+ Low Speed and PASSCode are global
options and their settings are the same for any Mode selected.
They will not change when the Mode or Program changes.
