  1. How do I get the latest version of FanTestic?

    Updates of FanTestic are released regularly.  How do I know if I have the latest version, and how do I get it?

    Users who are using the ADMIN shortcut with FanTestic or who have skipped an update will not necessarily be notified of the update when they start the software. 

    To install the new FanTestic:

    If you have a current version of  FanTestic, open it while connected to the internet, use the File menu>>Check for Updates  and then restart if it tells you that there is a new version available. (old versions of FanTestic do not have this option in the File menu, and some old versions have it but it can crash on some computers).

    If you have trouble installing the update using the "Check for Updates", uninstall FanTestic using the control panel and re-install from the following link:

  2. How do I know if I need to use the ADMIN shortcut in FanTestic?

    I have DM-2 gauges and FanTestic cannot communicate with them.  Does the ADMIN shortcut help me with this?

    Some computers need you to create the ADMIN shortcut to be able to communicate with DM-2 gauges.  Only some computers have a problem letting FanTestic communicate with the DM-2, and there is a special procedure to give FanTestic permission to access the ports. You do not need it for DM32 gauges (if you have a problem with DM32 USB, use the Ethernet option). 

    Check that you have the DM2 USB Device Driver installed (look in Control Panel).

    Run the DM2Checker from your start menu. (if this is not in your start menu, then you need to install the DM-2 USB device driver from the website).

    If, and only if, you see the "error 5: access denied" message while running the DM-2 Checke

  3. How do I install FanTestic or Integrity using Chrome, Firefox, or MS Edge browsers?

    If you are using a browser that is NOT Microsoft Internet Explorer you may get errors when you run the setup.exe that you downloaded.  If you get errors, use Microsoft Internet Explorer and choose to "Run" the installer from the internet rather than downloading.

     The FanTestic and Integrity installer relies on the use of the Internet Explorer Browser, as do all applications distributed using ClickOnce technology.  In order to successfully install, start Internet Explorer on your computer and navigate to the download link in Internet Explorer.  If your computer has a different browser set as default, you will have to copy the link from that browser into Internet Explorer.

    On Windows 10, the new Microsoft Edge browser is NOT Internet Explorer.  On Windows 10, you must type "Internet Explorer" into the Cortana search bar and choose to open "Internet Explorer (desktop)".

    If you continue to have errors installing when using Inter

  4. My duct test using DW/143 is not compliant, what am I doing wrong?

    I am doing duct testing and use the DW/143 standard (UK).  FanTestic keeps telling me the test is not compliant, what am I doing wrong?

    FanTestic checks that you have held the ducts at the test pressure for at least 900 seconds.  If you do not, the test will show as not compliant.  If you did a manual test and are entering the information into FanTestic, be sure to enter the time over which the test pressure was held.  If this is greater than 900 and your other test conditions are correct, the test will show compliant. 

    Compliance means the test conditions comply with the stated requirements for a test  in DW/143.  Pass or fail means that the measured results are within the required level.

  5. How do I pass a small room?

    I am having diffuculties passing a small room with an integrity test.  Is there anything I can do or allowances I can make?

    1. Make sure all the sealing has been completed.
      1. Most often small rooms leak at the wall to lower slab joint. This must have a continuous caulk bead from the sheetrock to the concrete slab.
      2. Next, check the wall to ceiling slab joint. It must be continuous and can usually be sealed with expanding foam. Paint over with intumescent paint if a fire rating is a concern.
      3. Next, all cable bundles must be checked for leaks through the center of the bundles. Separate the cables and sealed between each cable.
      4. All ducts entering or leaving the space must be dampered but even when seating properly those dampers alone may be enough to make the room fail. A smoke tight damper must be used.
    2. If a suspended ceiling is in place.
      1. Consider flooding the space above the suspended

  6. How do I get the factory default report template for FanTestic?

    FanTestic provides a report template that users with Pro licenses can customise.  If users have done customizations and not given the template a name different than the default template, they will not always be able to see the new factory template after a FanTestic update.

    FanTestic provides a report template that users with Pro licenses can customise.   This template can then be used when the user generates a report from their test data. 

    One  way to get a copy of the current factory default template is to use the menu item in the File menu called "Customize Report Template".  This will create a copy of the factory default template in the MyDocuments\Retrotec\Templates directory with the name of the factory default template plus "_To_Customize-[yyyy-MM-dd]".

    The default Template is named with the name of the standard you are using, and the language.   So if you are using ASTM standard with t

  7. Why is the positive peak pressure for FM200 zero or negative?

    How can the positive peak pressure be calculated as a negative number or zero when there is a value provided for the leakage area required for venting?

    The calculation of peak pressures depends on a curve, and when the circumstances are particular, the peak pressures can be very close to zero.  The curve is not optimized in this area, as peak pressures near zero are not a worry.  Integrity makes the value of peak pressure zero when the calculated value using the curve goes below zero, as at this point it does not matter how small the pressure really is.

    Previous versions of the software variously showed the positive peak pressure as negative or as a blank instead of a zero. 

    - blanks instead of zeros in report are fixed in Integrity versions >
    - peak pressures showing negative instead of zero in the UI fixed in Integrity versions >

  8. How can I get rid of the warning about envelope area in FanTestic Integrity?

    When calculating hold time using FanTestic Integrity software, I am getting an error which says "Envelope area not specified. Unable to determine permeability result." but there is no place to enter envelope area.  How can I get rid of this warning?

    If you are seeing the following error:

    you can prevent it from coming up by modifying your settings.xml file.

    You can find your settings.xml file in your MyDocuments/Retrotec/AppData directory.  Open it using Notepad (you can right-click on the filename and choose "Open with" and then click on "Notepad").

    If you are using one of the NFPA standards, add the following text to the file:  <Setting Name="NFPAPermeabilityRefPa">0</Setting>

    When you are done it should look like:

  9. Can I install FanTestic on a Windows 8 computer?

    FanTestic will install properly on a Windows 8 computer, as long as it is full Windows 8 and not one of the tablet or phone versions of Windows 8. 

    Make sure to disable anti-virus while doing the download and install. 

    Be sure to “Run” the installer from the internet using Internet Explorer browser, do not download it to the computer and then run it.

    If you have trouble installing FanTestic, you can first install the DM32 USB Driver directly from the website (the version on the website has an up to date certificate) and then run the FanTestic installer. 

    (Older versions of the FanTestic installer had a DM32 USB Driver which did not have an up to date security certificate so some settings on Windows 8 could cause it to reject the installation. )

  10. Where do I place the exterior pressure pickup tubes?

    The exterior pressure reference for the differential pressure measurement across the door panel is provided by the red tube.  The exterior pickup location must be chosen to minimize the influence of wind, sun and atmospheric pressure on the differential measurement, or measurements must be taken to allow correction for these influences.  Each standard defines what is expected in terms of the exterior reference pressure measurement.  Use Table 2 to determine where best to locate your red tube depending on the standard procedure you are following.

    Table 2:  Locations for Exterior Reference Pressure Pickup as required by the various Standard Procedures

    Exterior pressure pick-up locations from Standards
