Introduction
The Touch Display is used to communicate to Supervisaire control board as local
and/or remote operator panel.
Touch display features:
• Large, easy to use color display with touch screen interface
• SD card for storing menu structure and backup files
• Easy firmware and menu upgrades
• Backup/restore system configuration data to/from the SD card
• Save system log files to the SD card when not connected to WebSentry®
Installation
The Touch Display communicates over a RS-485 serial port. The display is
equipped with a RJ-45 socket so it is recommended to use a CAT5 or CAT6 cable
between display and control board.
Supervisaire hardware has a dedicated RJ-45 socket intended for connecting
the touch display to the board. If the display is mounted in or near the system, all
you need is a standard Ethernet cable with RJ-45 plugs on both ends. If you
want to add a second display in a remote location, you must use header J8 for
this purpose (see page 5).
Below is a description of different ways to wire the touch display to the
Supervisaire control board.
Page 5
USE R M ANU AL
TOUCHSCREEN 2.1 5 SEPTTEMBER 12, 2017
Using the RJ-45 socket
Use a regular Ethernet cable and plug one
end into the back of the display and the other
end into the socket on the board. If you build
your own network cable, crimp a RJ- 45 plug
onto each end using the T568-A wiring
standard described on page 6.
WARNING! Do NOT connect another serial
port device, including another touch display, to
the port C terminals on header JCOM when
the RJ-45 socket is used!
RJ-45 socket and header JCOM share
communication port C.
Figure 1. RJ-45 socket
on Supervisaire board
Using Port D on J8
If you want to connect a second display you must use Port D on header J8.
If you have a premade cable, cut off one connector. The other connector should
be plugged in to the display. If building your own cable, use the T568-A wiring
standard described on page 6
The wires on the cut end are wired to header J8 as follows:
Pin 1 – Solid and striped blue wire
Pin 2 – Solid and striped brown wire
Pin 5 – Striped green wire
Pin 6 – Solid green wire
Page 6
USE R M ANU AL
TOUCHSCREEN 2.1 6 SEPTTEMBER 12, 2017
Using Port C on JCOM
Since port C is shared by header JCOM and RJ-45 socket, JCOM header could
be used for communication only if RJ-45 is not in use.
As for header J8, use either a premade Ethernet cable and cut one end or build
your own cable using T568-A for the display plug.
JCOM is wired as follows:
Pin 4 – Solid and striped brown wire
Pin 5 – Solid and striped blue wire
Pin 6 – Striped green wire
Pin 7 – Solid green wire
Attaching a RJ-45 Using the T569-A Wiring Standard
When attaching a RJ-45 connector to the end of a CAT5 or CAT6 cable, use the
T568-A wiring standard. This applies to both ends if you plan to use the RJ-45
socket on a Supervisaire control board.
With the connectors on the plug facing towards
you (see Figure 2), the order of the wires from
left to right are:
• Striped Green
• Solid Green
• Striped Orange
• Solid Blue
• Striped Blue
• Solid Orange
• Striped Brown
• Solid Brown

Starting Up
When the display is powered up, it will try to communicate with the Supervisaire
control board. During this time, a Start page is displayed. If no connection is
established within a few minutes, the display will proceed to the Home Page
where you will have access to some functionality. You will have access to
display settings like serial port configuration and a serial port status page for
troubleshooting purposes. In event of other communication issues (like missing
SD card or display calibration loss), respective message would be displayed –
refer, as needed to Troubleshooting (page 26).
If you just have started or restarted the commissioned Dectron system, you
should see a page with two buttons where you can choose to start the system in
Normal mode or Service mode (Figure 3). After selecting Normal mode, or if the
system is already in Normal mode, the normal home page should be displayed.
After selecting Service mode, or if the system is already in Service mode (just
delivered from factory and/or Non-Commissioned system), the service home
page should be displayed.
Figure 3. Normal/Service Mode selection page.
• Normal Mode allows for system automatic operation, based on system
control algorithm, configurations and setpoints. It is standard operational
mode, that does not require operator interference or control.
• Service Mode allows for manual control over the system operation.
Service mode is intended for system initial start up and
troubleshooting purposes – it must be used only by trained
professionals.
o To facilitate troubleshooting process, some safeties/alarms
(except for major ones), as well as some “Normal Mode”
control sequences are omitted in Service mode.

Touch Display – Layout and Navigating
The default page after starting up or rebooting the display is the home page.
Normal Mode. Home Page layout and navigating
Unless you navigate to other pages, the home page is displayed when system is in
Normal mode. It focuses on displaying critical system operation information.
Figure 4. Normal Mode home page (NE/NP series with one pool).
Some information, displayed on Normal mode home page, would be available on
Normal mode home page only (Readouts), while the rest (Date&Time, Status and
Menu) would be displayed Service mode home page also.
Readouts
Home page will always show the room air temperature (Temp) and relative
humidity (Humidity) sensor readings. For systems, configured for pool water
heating, it will also show the pool water temperature (Pool), including pool 2 if
configured to heat two pools.
Temperatures, room air and pool water, could be displayed in either Fahrenheit
(default) or Celsius (optional) degrees.

System Restart and Display Restart
One of the most often used user command option is System Restart. It allows for
two separate commands:
System Restart
This command is used to stop the system and to switch, if needed, between
Normal and Service mode.
• Once system is restarted and Normal/Service mode selection screen is
displayed (as shown on Figure 3), you’ll have 60 seconds to decide
what mode to select – if nothing is selected, system will automatically
assume Normal mode operation.
It is also recommended to restart the system after Advances settings (see below)
adjustment (to ensure these adjustments are taken by system control in timely
manner).
To restart the system, tap the User button and then System Restart. Next, tap the
System Restart button to initiate a system restart. The touch display will display a
Shutting Down page until it loses communication with the SuperviseAir® board.
At this point, it will reboot the display. The normal display start-up sequence will
then commence.
Restart Display
To reboot (restart) the display, tap the User button and then System Restart.
Next, tap the Restart Display button to initiate a reboot of the display itself.
Use this feature if it seems like the display has lost communication with the
SuperviseAir® board but you still can navigate the menu system. You will
always be able to reach the System Restart menu selection unless the display is
completely frozen.
One other time when you need to do this is if you take out the SD card. After
plugging in the SD card again you must restart the display before it can be read
again.
Advanced
The Advanced page allows to view and adjust system’s control settings and
configurations.
CAUTION! Improper/incorrect Advanced settings may cause system malfunction
and premature failure! Once you click Advanced button, before allowing to
proceed, touch display will issue respective warning.
Page 14
USE R M ANU AL
TOUCHSCREEN 2.1 14 SEPTTEMBER 12, 2017
The Advanced page consists of two button groups, arranged into three columns
(see below):
Figure 9. Advanced page
The first two columns (left and center, dark-blue buttons) show Factory
Settings menus (same as displayed in WebSentry®). These settings would
define system operation and would include following:
Environment
Dehumidification, heating, cooling, and pool heating
controls settings (space heater type, deadbands, space
heating/cooling control type etc.)
Ventilation
Ventilation control settings (blowers’ speeds, economizer
and purge parameters, timers etc.)
Compressors
Compressors control settings (number of compressors,
refrigerant type, alarm and operational pressure and
temperatures levels, timers, other operational settings)
Sensors
Sensors parameters (calibration, type, usage etc.)
Controls
Inputs/outputs configuration (limits, polarity, availability)
I/O Assignments
Sensors and Inputs/Outputs control board assignment
Network
Communication settings (TCP/IP, BACnet, other com
protocol configurations, serial ports settings etc.)
TouchScreen
Touch display settings (temperature degrees’ type
preference, date and time format, display password etc.).
Settings are stored only on the SD card and are unique
for each display.

TOUCHSCREEN 2.1 15 SEPTTEMBER 12, 2017
Finally, when system is set in Service mode, Factory Settings group, in addition
to listed above, would have Service button (see Service Mode on page 18 for
details).
The last column (right, light-blue buttons) shows menu selection for Advanced
Troubleshooting features such as viewing all system sensors’ readouts, current
controls and sub-systems’ statuses etc.
In addition, this group has Tools menu selection with the following advanced
features (mostly – for communication/IT or touch display-related troubleshooting):
Ping Network
Ping network address. Use this feature when
troubleshooting a WebSentry®® connection
Serial Stats
Serial port counters are used for troubleshooting serial port
communication interface. For a robust and stable
connection, you want to see most error counters at 0 or a
very low number compared to the total number of
messages
System Backup
Use this feature to backup all control settings to the SD
card. You can also use it to restore settings from a backup.
Factory Default
Use this feature to reset settings to factory default. All
current settings will be lost. Use this feature as a last
resort only, when experiencing strange system behavior.
This can be the result of corrupt control module (subboard) memory and restoring to factory defaults should
resolve most memory corruption issues.
Firmware
Update
Use this feature to update touch display firmware. See
Updating Firmware on page 24 for more information.
Navigating Advanced page and adjusting Advanced settings is similar to
described above User setting adjustments (see page 11-12).
Note. Displayed content depends on the system’s series software, configurations
and settings (Advanced). For example, if system is not configured to have a pool
heating, all pool heating related features would not be shown (pool water
temperature setpoint in User menu, Pool water temperature sensor reading in
Readouts, Pool Heat status indicator in Status etc.)

• There are no sensors displayed – Readouts are replaced with a
SERVICE MODE warning to use caution while in service mode.
• There are no mode status indicators.
• Service mode menu buttons are shown on the bottom of the display
(under the Time&Date).
Service mode menu buttons allow for manual access and control of respective
system’s components to facilitate testing and/or troubleshooting of these
components.
The components are divided into groups: Ventilation (main blower, exhaust fans,
outdoor air dampers and heat recovery), Heating (both space heating and pool
water heating), and Compressor (one menu button for each compressor circuit, if
current system is configured for two compressors).

Components control page layout (see Figure 13) and navigation example below
is shown for Ventilation group; same would apply to other Service mode group(s).
Figure 13. Service mode control page – Ventilation.
Service mode control page provides following:
• Readouts (left column) displays sensors readings pertinent to current
group (in this case – air temperatures, humidity etc.)
• Control buttons allow to manually operate/control respective
component/device. Green button indicates that given device control is
engaged/active; white – otherwise. Control buttons are segregated
horizontally (by slightly wider gap – see red line) into two groups:
o Digital Outputs (TOP group) - engages or disengages on/off
controlled devices (as shown on Figure 13 - RA Damper is
engaged (ON), and Exhaust Fan 2 start signal is engaged (ON)
also). Simply press respective button to engage or disengage
o Analog Outputs (BOTTOM group) – sets/adjusts modulating (0-
10 VDC) control signal. Press respective button to select
desired device and adjust value of modulating signal. Figure 14
shows main blower speed signal being set to 35%; if needed,
this value could be increased (by pressing” +”) or decreased
(by pressing “-“). Pressing “Reset” will set it to zero.

Service Mode – Commissioning.
Advanced settings in Service mode, in addition to ones, listed in Normal mode,
would also include Service button. It allows for access to following features:
• Commission – allows to commission/de-commission the system.
o Systems, delivered from Dectron Company are set to be Non-
commissioned (decommissioned) – this ensures that system
would not convert to Normal mode after restart or power up
without being commissioned by start up agent. Once system
is successfully started up, it must be Commissioned to allow
for Normal Mode operation.
o Commission feature also displays Tested feature; it’s used at
the factory testing facility and is not revertible, once set to yes.
• Core Config – allows to adjust system serial number (rarely used) and
control board version (in case of board replacement with one of different
version)

TOUCHSCREEN 2.1 22 SEPTTEMBER 12, 2017
SD card - File Structure
The SD card contains a normal file structure using the 8.3 filename convention (8
characters for name and 3 characters for extension, spaces not allowed).
You can put any files on the SD card. The touch display will only read and look at
files and folders known to the firmware.
At the root level, there are only two files used by the touch display. TSCALIB.BIN
is the display calibration file discussed in further detail under touch display
calibration on page 25.
The file FIRMWARE.BIN is a temporary file that will trigger the touch display to do
a firmware update. The touch display will automatically delete the file when the
update has completed successfully.
These are the folders used by the touch display:
DATABASE
Contains all files required to display menus, settings, settings help text, etc.
These files are a text version of the database used by WebSentry®.
For this reason, it should be very easy to find settings on the touch display if you
are familiar with where to find it in WebSentry®. The structure and order of
settings are the same between WebSentry® and the touch display.
HELP
Contains all context sensitive help files as well as alarm information help files.
DISPLAY
Contains a file named CONFIG.DAT with all saved Display settings. If you delete
this file, the touch display will return display settings to defaults on reboot.
It also contains an optional NOTES folder where all notes are stored (if you have
saved any notes).
BACKUP
This is where all system backups are stored. Backups are saved with the
filename YYYYMMDD.BAK where YYYY is year, MM is month and DD is day.
Page 23
USE R M ANU AL
TOUCHSCREEN 2.1 23 SEPTTEMBER 12, 2017
LOGS
Contains all log files. At the main folder level, you will see log data files containing
information about the last fetched log entry. One file for each log type.
The log entries are stored in separate files in time stamped sub folders. Contents
of these sub folders can be saved to your PC and sent to Dectron for analysis.
FIRMWARE
Contains all saved firmware files accessible from the Firmware Update page.
Updating the Firmware
Most of the menu and help system displayed on the touchscreen is controlled by
files stored on the SD card. However, as for most devices, there is also a piece of
software installed on the displayed referred to as firmware. Firmware updates are
required to resolve software faults and when improvements are made to the
display interface
Follow these steps to update the firmware:
1. On a PC, download the firmware file from WebSentry® using the
Download toolbar button
2. Remove the SD card from the touch display and plug it into the SD card
reader of your PC
3. Save the firmware file in the FIRMWARE folder on the SD card
4. Reinstall the SD card in the touch display and from the User settings
menu, select System Restart and then Restart Display
5. Select the Advanced menu, then Tools and finally Firmware Update
6. Select the firmware file from the list on the left. The files are named
FW010203 where the number indicates the firmware version. In this
example, the version would be 1.2.3.
7. Tap the Install button and the firmware update process will start. Please
do not unplug the display or shutoff the power to the system while the
firmware is updating. The display will show a large progress bar while
updating the firmware
If the new firmware is not installed, you can try a second method to update
firmware. Follow these steps if above process did not work:
Page 24
USE R M ANU AL
TOUCHSCREEN 2.1 24 SEPTTEMBER 12, 2017
1. Remove the SD card from the touch display and plug it into the SD card
reader of your PC
2. Copy the firmware file from the FIRMWARE folder to the root folder (e.g.
D:\)
3. Rename the file to FIRMWARE.BIN
4. Reinstall the SD card in the touch display and, from the User Settings
menu, select System Restart and then Restart Display
5. The firmware will now be updated and, when finished, the display will
continue with the normal start-up sequence
6. The FIRMWARE file will be saved to the FIRMWARE folder on the SD
card with the proper filename structure and removed from the root folder
7. WARNING! If the firmware file is corrupt, the update will not complete
and the file not be removed. This will result in cyclic restarts and never
getting to the Home page. Delete the FIRMWARE.BIN file if this
happens
Updating the Menu and Help Files
Most of the menu and help system displayed on the touchscreen is controlled by
files stored on the SD card. As Dectron releases new versions of the control
software, new settings will be added and other ones will be removed. There will
be improvements to the help system based on feedback from users. To apply
these changes to any touch display is as simple as replacing the menu and help
system files on the SD card.
These updates will be prepared as update packages with a menu version
number. You can see the currently installed menu version from the Firmware
Update page.
To install updates, follow these instructions:
1. Download the menu update package from WebSentry® using the
Download toolbar button on your PC
2. Remove the SD card from the touch display and plug it into the SD card
reader of your PC
3. Copy the package file (ZIP file) to the root folder of the SD card
4. Delete the DISPLAY and HELP folders
5. Unpack the ZIP file. Typically, you can do this from Windows by right
clicking the file and selecting Extract Here from the menu
6. Delete the ZIP file
7. Reinstall the SD card in the touch display and, from the User Settings
menu, select System Restart and then Restart Display
You should now see all menu and help file changes.

Touch Display Calibration
It is critical that the touch screen is calibrated so that the hardware can properly
translate a physical interaction to a visual object representing, for instance, a
button. If not calibrated correctly, pressing a button might not trigger an event or
trigger the wrong event by executing the press of a different button.
Normally, touch display comes pre-calibrated from the factory, yet in some cases you
may need to perform the calibration:
• If touch display is started up for the very first time, or
• If touch display does not respond correctly to the touching of the
buttons (pressing button does not trigger respective/correct event),
which could be a result of corrupted calibration file.
To initiate touch display calibration, you could do following;
• Manually delete the calibration file TSCALIB.BIN, located at the root
level on the SD card.
o Calibration parameters are saved in a calibration file; once file
is deleted, on the power up of the touch display you’ll be
prompted to calibration.
• Manually “force” the touch display calibration:
o While pressing with your finger on the touch display
(anywhere on the display), unplug the touch display for couple
seconds, then, still pressing your finger, plug/power up touch
display back. This should prompt the calibration also.
Figure 16. Touch display calibration.
When asked to calibrate the display, follow the instructions on the display (see
Figure 16). You will be asked to tap the four corners and then one more time
anywhere on the screen to save the calibration data. Please take your time and
tap right in the center of each circle to get the most accurate calibration.

The Sent status counts up every time a message is sent from display to
Supervisaire board. Received counts up when a message is received from
Supervisaire board.
Sent and Received numbers should roughly be the same. If Received is 0, it
means no messages are returned at all. The cause can be misconfigured serial
port, faulty serial port or a wiring issue.
If messages are being received but you have a lot of lost messages (Received
much lower than Sent), this suggests a non-robust connection. Same thing if you
have a lot of fault messages, other stats not being 0 and having high numbers.
In unlikely event of non-robust connection, you can try changing baud rate and
timers:
• Start with changing baud rate to a lower speed. For instance, 19200 or 9600.
You need to make the change both from TouchScreen Display and
Supervisaire board. See verify port configuration descriptions above for how
to access configuration pages.
• On the TouchScreen you can also try changing the Response Timer and
make it a little bit longer.
• For TouchScreen display, select Advanced, TouchScreen and then Serial
Interface.
• You may need to verify and/or adjust certain parameters in the
system software via direct communication via Supervisaire control
board – you’d need special communication operator panel for that
(contact Dectron Service group for support).
Verify TouchScreen Port Configuration
Select Advanced, TouchScreen and then Serial Interface. Default configuration is
baud rate 57600 and response time 1000 ms. Ensure this has not been changed.

Try Connecting to Supervisaire Board at the System (for Touch Display
Remote Installations)
If you are installing TouchScreen display as a remote panel, try using a short
patch cable and connect directly to the board to determine if there is a fault with
the long wire between Supervisaire board and remote location.
If you get a connection locally, replace or troubleshoot wiring between system and
remote location.
Try Connecting to Different Port
Try connecting to a different port. Port D instead of port C or vice versa. If you
now have a connection, the other port is faulty. If you only need to use one port,
you can leave it this way. Otherwise, order a replacement control board.
If neither port works, order a replacement control board. Both ports are most likely
faulty.
Port C Only Used by RJ-45 Socket or JCOM
Pin 6 & 7 on JCOM share the same comm port (port C) with the black RJ-45
socket on the control board (Figure 1), therefore only one device could be
connected to these two terminals (JCOM and RJ-45 could NOT be used
simultaneously for two different devices) because of a very high risk of producing
communication conflict over the port.
If JCOM (6 & 7) is being used, remove wires before using the RJ-45 socket. You
can also wire TouchScreen display to J8 using port D.
