II. MOUNTING INSTRUCTIONS
(General)
INDOOR MOUNTING ONLY - Environmental/Insect/Dust Control The Architectural Low Prole 8 Air curtain is designed to be an eec­tive barrier against cold drafts in the winter and hot air in the summer. To achieve optimum protection, the air curtain should be mounted on the inside of the building, ush to the wall and as close to the top of the door opening as possible. To ensure peak performance, keep the air stream free of obstructions.
The air curtain 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.
Before mounting the air curtain, check the supporting structure to veri­fy that it has sucient load-carrying capacity to support the weight of the air curtain(s). The mounting hardware (supplied by others) should be capable of supporting a minimum of three (3) times the weight of the air curtain.
See Table 1.
If the air stream strikes any obstruction (the top edge of the doorway, a door opening device, etc.), the eectiveness of the air curtain will be greatly reduced. See Figure 1. B. For optimum performance, the bottom of the air curtain (discharge nozzle) should be no more than 1” above the top of the door opening with the air curtain(s) mounted ush to the wall. If the air curtain must be mounted higher, it must be spaced out from the wall ³/₈” for every inch the air curtain is above the door opening. See Figure 3. For optimum protection, any void between the air curtain and the wall should be sealed along the full length of the air curtain. C. Electric heated air curtain(s) shall:
1. Have a minimum clearance of at least 1” between the sides and top of the air curtain and any combustible material.
2. Have a minimum clearance of at least 6’ between the bottom of the air curtain and the oor.
3. Be installed Indoors Only. D. Proceed to either Section III - WALL MOUNTING or Section IV - SUSPENDED MOUNTING
III. WALL MOUNTING
A. The Architectural Low Prole 8 Air curtain is equipped with two ¼” threaded inserts on the back of each air curtain (two per module on air curtains 84” and over). Insert and tighten the shoulder bolts (provided in bag taped to the wall plate) into these threaded inserts. A minimum of two shoulder bolts are required; on air curtains comprised of modules, use the outer threaded inserts and a minimum of one of the inner threaded inserts.
IMPORTANT: A minimum of 1” is required above the top of the air curtain for the installation and removal of the cover housing. A. When determining the mounting location for the air curtain(s), make sure that nothing interferes with the curtain of air developed when the discharge vanes are directed from 0º to 20º toward the door opening.

NOTE: A minimum of 1” is required above the wall mounting plate to provide clearance for installation and removal of the air curtain.
C. Remove the wall mounting plate from the unit to install. The wall mounting plate (included) is designed to t ush with the top of the Architectural Low Prole 8 Air curtain. Therefore the location of the wall mounting plate will determine the nal location of the top of the air curtain. D. For Standard Flush Wall Mounting, position the center of the wall mounting plate over the center of the door open ing with the larger opening of the key hole slots facing up. The wall mounting plate thickness provides a natural ¾” space which allows for mounting it up to 4” above the opening. For optimum performance, the bottom of the mounting plate should be no more than 2” or less than 1” above the top of the door opening. See Figure 2. High Wall Mounting must be used if the wall mounting plate must be mounted higher than 4” above the door opening: the mounting plate must be spaced out from the wall ³/₈ ” for every additional inch (over 4”) that the air curtain is above the door opening (clearance height). See Figure 3. For optimum protection, do not exceed the recommended maximum mounting height of 8’ above the nished oor. Any void between the mount ing plate and the wall should be sealed along the full length of the mounting plate. E. Determine which of the four holes provided in each of the steel brackets of the wall mounting plate are located where suitable support is available for the air curtain. A minimum of one inside hole and one outside hole from

that are comprised of modules, remove the wiring tray cover that is located closest to the electrical rating nameplate. Remove the required knockouts and attach the necessary electrical hardware. Save the wiring diagram found inside of the wiring tray. See Figure 7. I. There are two sets of keyhole slots on the wall mounting plate. In low overhead installations, the air curtain may be
staged in the lower keyholes to provide clearance for electrical wiring and then moved to the higher key holes after completion. Raise the air curtain with the discharge
opening facing down toward the oor. While holding the air curtain level, slide the heads of the shoulder bolts into the larger hole of the keyhole slots of the mounting plate. Lower the air curtain into place, keeping both ends level, allowing it to rest ush with the mounting plate. See Figure 4. J. After attaching the air curtain to the mounting plate, ensure that the air curtain is seated and ush with the mounting plate on all four sides. K. Proceed to Section V - Electrical Connections.

each bracket must be used for proper support. Drill out the aluminum backing of the holes chosen with a ¼” drill bit. If the provided holes on the mounting plate are not located where suitable support is available, drill new holes in the space provided on the steel mounting brackets. F. Mark the wall in the centers of the ¼” holes drilled on the mounting plate. G. Attach the mounting plate to the wall (hardware by others). H. The top of the air curtain is provided with two knockouts on each side allowing for a left or right hand power connection. Remove the wiring tray cover; on air curtains
IV. SUSPENDED MOUNTING
(Ceiling Suspension) A. When the air curtain is top mounted, the wall mounting plate is designed to store on the back of the air curtain for future use. See Figure 5. B. Four (4) factory installed ¼” threaded inserts are located on the top of the air curtain for top suspension mounting; on air curtains comprised of modules use the outer threaded inserts. To eliminate the slight deection of longer air curtains, the inner threaded inserts may also be used. See Figure 6. C. Determine the exact mounting location of the air curtain. D. The top of the air curtain is provided with two knock­ outs on each side allowing for a left or right hand power connection. Remove the wiring tray cover; on air curtains that are comprised of modules, remove the wiring tray cover that is located closest to the electrical rating nameplate. Remove the required knockouts and attach the necessary electrical hardware. Save the wiring diagram found inside of the wiring tray. See Figure 7. E. Attach ¼” threaded rods or other suitable hardware to the top mounted threaded inserts.

NOTE: One Intelliswitch serial cable assembly (part #
505SC***INT485-A) is required for every unit that is to be used as a master/slave. “***” denotes length of cable in feet- “008” = 8 feet long.
For Master/Slave operation, a serial cable connection must
be made between the INTELLISWITCH GEN2 control boards of each unit to be linked.
1. Disconnect power to all the units.
2. Access the wiring tray on top of each unit by removing the screws that hold the cover in place.
3. Find the (RS485) phone jack couplers in the wiring trays. There will be two short cables in the wiring tray of each air curtain, each with a double ended female phone jack coupler attached to the cable.
4. The serial cable ordered for each unit will be coiled up in the wiring tray of the unit and connected to one of the couplers.
Note: There may be one less serial cable than the
number of units ordered. e.g. Two units together will need only one cable; three units together will need two cables, etc. Any extra cables can be kept as spares.
5. Use one of the extra electrical knockouts to route serial cable from one unit to the next. Be sure to protect the edge of the knockout properly.
6. Plug (RS485) male phone jack on the end of the serial cable into the empty coupler on the next unit.
7. Continue process for all units that are to be connected serially.
8. Serial cable connections are capable of two way com munication. It does not matter which coupler the cables are connected to.
9. The rst and last air curtains in the group will each have an empty coupler after all connections are made. So if there are only two air curtains 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 at telephone cable, phone jack connectors and the proper crimping tool.
G. Remote mounted Display Faceplate - if operation of the
Intelliswitch is desired through a remote mounted display face plate continue, otherwise skip to step H.
NOTE: Maximum mounting distance between the Dis-
play Faceplate and the unit is 20’.
The unit MUST be factory ordered with the remote mounted faceplate option.
1. When the remote faceplate option is ordered from the factory the air curtain comes equipped with
the blank faceplate and 12’ ribbon attached. The Diplay Faceplate is shipped loose ready for eld
installation.
2. Locate the male end of the 14-conductor ribbon cable in the wiring tray and run to the remote display loca tion. The cable is minimum CL2 rated and should not need to be in conduit.
3. Connect the ribbon cable to the 14-pin socket with red stripe positioned on the top left when facing the front of the display board.

VII. OPERATING INSTRUCTIONS
A. GENERAL OPERATION
Air curtain operation may be divided into four areas: control package, fan activation, fan speed selection, and heat activation. The air curtain must be properly installed before it is used.
1. Control packages control the unit’s sequence of operation. Unit modes/control packages are built into the unit and may not be changed in the eld.. Refer to your wiring diagram for specics about activation connections and sequence of operation. a. Basic Control Package – The unit is activated by a door switch. The door switch may be line voltage or low voltage (24V). b. Deluxe Control Package – The unit is activated by a door switch, but has a factory installed time delay allowing the unit to keep running for a period of time after the door closes. c. Comfort Plus Control Package – Available only on heated units, the unit is activated by the door switch OR by the thermostat to provide supplemental heating.
2. Unheated units will have the fans activated by a door switch or sensor. The unit speed can be selected from the
Intelliswitch display.
FIGURE 9 - Airow Adjustment
3. Heated units will have fans activated by a door switch or sensor, but may also be activated by the thermostat in Comfort Plus Mode. The unit speed can be selected from the Intelliswitch display.
4. Heat activation is controlled by either a unit or remote mounted thermostat, and a unit or remote mounted switch.
B. AIR STREAM ADJUSTMENT
1. With the air curtain operating and the door in its full open position, check to see that nothing is obstructing the airow at the discharge nozzle vanes.
2. Find the air stream split location. Hold a handkerchief by its corners, approximately 12” above the oor. Gently move the handkerchief back and forth in the doorway. Make sure the air is being directed to both the inside and the outside. See Figure 9. The split location is indicated where the handkerchief is vertical with minimal or no uttering.
3. The split location should be approximately 3” outside the doorway. If necessary adjust the discharge nozzle vanes by de-energizing the unit, loosening the nozzle vane locking screws and adjusting vanes.

VIII. MAINTENANCE AND CLEANING
CAUTION: ELECTRIC SHOCK HAZARD Disconnect power
whenever servicing unit. More than one disconnect may be required to de-energize unit.
Keep your air door operating at peak eciency by cleaning
the blower wheels, motor(s) and intake grille. Buildup of dust on the blower wheels can cause vibration, noise and excessive wear on the motor bearings. The frequency of cleaning will depend on the environment where the unit is operating.
Dirty, dusty or greasy environments could require a
cleaning schedule of once every two months. If the envi-
ronment is not that dirty, the unit(s) should be scheduled for cleaning a minimum of once every (6) months.
To access the interior of the unit: A. Disconnect the power to the unit; remove the intake grille by
removing the locking screws on each end of the unit. Lift the intake grille up and then towards you. See Figure 10.
B. Remove the bottom access panel by removing the phillips
head screws on the bottom of the unit.
C. Vacuum and scrape (if necessary) to remove the buildup of
dirt and debris. The motor(s) are permanently lubricated and require no additional lubrication. Reinstall the cover and intake grille.
D. Switch the power on after cleaning, reinstalling the cover and
intake grille.
CAUTION: STAND CLEAR OF THE UNIT OR WEAR SAFETY
GOGGLES AS LOOSE DEBRIS MAY BE PRESENT AND MAY EXIT THE NOZZLE.
IX. SERVICE
CAUTION: ELECTRIC SHOCK HAZARD Disconnect power
whenever servicing unit. More than one disconnect may be required to de-energize unit.
Any service performed on the Architectural Low Prole 8 air door
MUST be done by qualied personnel.
Berner air doors require very little servicing. All parts are eas-
ily accessible for periodic inspection and maintenance. Units should be cleaned at least twice a year. Your particular appli­cation (the amount of dirt and dust in the air) and location of the unit(s) will determine how often your unit(s) will need to be cleaned and serviced. All motors have permanently lubri­cated, sealed, sleeve bearings and require no maintenance.

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 Architectural Low Prole 8 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 dicult 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 display still doesn’t light, unplug the speed sensor and thermostat probe (if a heated unit) from the control board. If the display lights, plug one component back in at a time to see which one may be shorted. The faulty component will make the display go blank again.
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
12
Page 13
INTELLISWITCH™ FAQ’s Continued (Frequently Asked Questions)
www.intelli-how2.com
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 and labeled 9 & 10.
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 qualied 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 eect 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 conrmation.
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 dierent 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.

6.11. Error Codes
The Intelliswitch has six error codes, 1 through 6, to help 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
Appendix - 17
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 identied the control will reset all settings (except for Speed Range) back to Factory default values. Because some speed ranges are not compat­ible with all motors, the proper value cannot be automatically set and therefore requires user input. This is prompted by the scrolling “Set FACt SPEEd” on the display. Solution – press the “OK” button. This will open the range set­ting identied by “rn”. Select the correct speed range (see Sec­tion 7.1) based on the Series/Model. Press “OK” button.
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 conguration 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. None of the settings need to be changed.
7. Factory Menu – Service Personnel Only
The Factory Menu must be entered from the DIAG header. To enter into the Factory Menu hold down the right arrow for 5 seconds. DIAG will display when the Diagnostic Menu is avail­able. From the DIAG display, press and hold the up and down arrows simultaneously for 10 seconds. FACT will display when the Factory Menu is available.
Note: When the Factory Menu is accessed it automatically shut the unit o by changing the Mode to OFF.
The Factory Menu is used to change or reset core settings to change base functions or resolve Intelliswitch™ errors. The Factory Menu allows parameters for the following options to be set:
• Speed Range Setting
• Restore Factory Default Settings
• Reboot Software
• PASScode
• Supply Voltage Frequency To enter into the Factory Menu from the header press the down arrow. Use the left & right arrows to change setting values. Use the OK button select action and return to the User Menu.
7.1. Speed Range: single level rn N 0 – 1 – 2 – 3 – 4 – 5 – 6 – 7 – 8 – 9 – 10 -11 – 99 O Select the fan speed range from 0 to 11 using the left or right arrows. The speed range for each unit is located on the unit wir­ing diagram called out in a box in the Intelliswitch® schematic by “SPEED rn __”.
Page 18
Note: Selecting the incorrect speed range can damage the motor(s) beyond repair and potentially create abnormally high temperatures.
Speed ranges are dependent upon the air curtain Series, motor type and heat option. ALC08(1/5 hp) – all voltages use ranges 0-2 Available ranges are: 0 = ambient – variable 10-speed, 600 rpm to full 1 = ambient – variable 10-speed, 1050 rpm to full 2 = heated – variable 10-speed, 1250 rpm to full 3 = ambient – full on, no adjustment 4 = heated – full on, no adjustment (monitored) 5 = heated – full on, no adjustment (not monitored) 6 = ambient – multiple 3-speed, ITC relay control 7 = heated – multiple 3-speed, ITC relay control 8 = ambient – variable 3-speed, 1250 rpm to full 9 = heated – variable 3-speed, 1250 rpm to full 10 = ambient – multiple 2-speed, ITC relay control 11 = heated – multiple 2-speed, ITC relay control 99 = lock out – scrolling request for user input
7.2. Thermostat Probe Mode: single level
In “St” (Standard) mode the lowest operating point for the thermostat probe is 34°F (1°C). Below this temperature there will be no call for heat and “nP” (no Probe) will display on the diagnostics menu. In “Cd” (Cold) mode the thermostat will operate below 34°F (1°C) but disables the “nP” (no Probe) feature and will call for heat on a probe failure or if it is disconnected. St - Standard mode, locks out below 34°F (1°C). Cd - Cold mode, works below 34°F (1°C).
7.3. Restore Factory Default: single level
DEF N n – U – P – A – tO If it is necessary to restore any of the controls settings back to the factory defaults, select DEF using the down arrow. Select the factory setting restore type using the left or right arrows. This will reset the option settings back to the factory default settings. Available selections are: DEFn – no changes DEFU – reset User Menu ONLY settings DEFP – reset Programs ONLY settings DEFA – reset ALL settings (user and program) DEFt – set controller to factory TEST parameters
7.4. Reboot Software: single level

7.5. PASScode multi-level
N PAS y – PAS n O Select y to enable the PASScode feature and n to disable. When active, the PASScode feature requires that a four digit code be entered to unlock the control. The code is: 2376
8. External Connections
There are three types of external connections available on the Intelliswitch™.
• Door Switch
• External Thermostat
• Serial Connection
8.1. Auto Mode Activation
When terminals 9 and 10 in the junction box are connected (closed), the Auto, Deluxe, Plus and Programmable Modes are activated. The Intelliswitch™ uses a low 5 volt DC voltage signal to monitor contact closure.
8.1.1. Door Switch (limit switch)
The door or limit switch is used in conjunction with the Auto, Deluxe, Plus and Programmable Modes to signal that the door is open. Connect the door or limit switch to terminals 9 and 10 in the air door junction box.
8.1.2. Building Management System
A building management system or dry contact closure can be used to activate the air door through the Auto, Deluxe, Plus and Programmable Modes. Connect applicable contacts to termi­nals 9 and 10 in the air door junction box.
8.2. Heat Mode Activation
When terminals 6 and 7 in the junction box are connected (closed), the Heat Mode is activated for all Operating (On, Auto, Deluxe, Plus and Programmable) Modes. The Intelliswitch™ uses 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 air door 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 air door junction box.
8.3. Master/Slave Operation
For Master/Slave Operation a serial cable connection must be made between all Intelliswitch™ controls of each air door to be linked. Once air doors are linked all Menu settings made through any air door display or remote control will transfer to all other linked air doors. Parameter changes made on any linked air door will update all other boards “live” upon menu selections.
7.6. Line Frequency: single level
N Fr Au – Fr 60 – Fr 50 O
The Intelliswitch® default is to automatically sense the line volt­age frequency. If it cannot be determined automatically, the line frequency may be manually selected. Au – Automatically Sense 60 – 60 Hz power supply 50 – 50 Hz power supply
Appendix - 18
9. Infra-red Remote Control
The handheld infra-red remote control buttons, layout and operation are the same as that on the Intelliswitch™ air door 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.
