1. PREPARING THE .NBT FILE

Before you can start the upgrade to PROSOFT 5, make sure you have a suitable PROSOFT 4 “.nbt” file that you can then open in PROSOFT 5 and save as a converted “.nbt5” file.
Below are the various steps to take for this.

IMPORTANT: This ‘major’ upgrade cannot be done remotely. You have to be on site for this, but you will see below that you can already prepare a lot before going to your customer. We also strongly recommend this to prevent possible loss of time, if something goes wrong during the preparation for which you need external support.

1.1. PROSOFT 4

First open your existing .nbt file in PROSOFT 4.0.4.0 (or higher).
Make sure your PALAS/DOMUS is running on PROSOFT 4.0.4.0 version before you start the upgrade.
NOTE: this is only possible for the G3 PALAS & DOMUS control panels. If you still have an older G2 or G1 control panel, you must first replace that control panel(s) with a G3 control panel and run it on PROSOFT version 4.0.4.0 (or higher)

1.2. CLEANING UP THE .NBT FILE: UNUSED FUNCTIONS.

With this upgrade, it is best to also clean up the file, such as removing as many unused functions as possible, so that they do not cause any problems.
To do this, open PROSOFT 4.0.4.0 (or higher). You can look in the hierarchical list (press the icon at the top ) to see if there are any unused functions. You must first remove these. Click on the menu item ‘unused functions’.

1.3. CLEANING UP THE .NBT FILE: FUNCTIONS WITHOUT OUTPUTS

In the same way, you can also remove functions that no longer have any outputs. Perhaps first check where they are still linked to, then you can also clean up the necessary there.
Now save your .nbt and send it, still with PROSOFT 4, to the central(s) of your installation.

1.4. UPGRADING OPUS TOUCH SCREENS

If there are one or more OPUS touch screens in your installation, you should now first upgrade them to the latest software version, before you install PROSOFT 5.
To do this, go to the “diagnostics” menu in PROSOFT 4 – “interfaces”, and UPGRADE the OPUS touch screens present, by clicking the “UPGRADE” button. This will save you extra time than if you had to do this afterwards in PROSOFT 5.
Note: You have to make sure that your OPUS screens have access to the internet via the LAN because the OPUS devices retrieve their upgrade file from the TELETASK cloud servers.

1.5. INSTALLING PROSOFT 5

Now install and start the latest version of PROSOFT 5 on your PC (Pro Downloads – Software, from the Professional website https://professional.teletask.be/ .
Open the existing .nbt file, but PROSOFT 5 will filter by default on the new “.nbt5” extension and will therefore not automatically show your ‘old’ .nbt file.

Change the filter button to the old “.nbt” extension (from PROSOFT 4):

Now select and ‘Open’ your most recent PROSOFT 4 file.

1.6. NOTES WHEN OPENING THE .NBT (4) FILE

There is a chance that you will receive additional messages when opening the file, which require specific actions.
Most messages may concern the fact that PROSOFT 5 no longer supports certain (very old) interfaces. Below is an example of such a message:

If you have the possibility to first tackle this problem in PROSOFT 4 and solve it in advance, this is the recommended method. If this is not possible, you should immediately look at this problem and solve it in PROSOFT 5 after opening the file. This means removing the interface from the file and also removing it from the AUTOBUS, because it can no longer function within a G3 - PROSOFT 5 installation.

There is a reasonable chance that you will also receive the comment “OS build to old”:

This means that your G3 central unit still has an early firmware version in the flash memory. In this case, you must first perform a “factory reset” of the central unit(s). See below in the chapter ‘hardware preparation’ how to do this.

1.7. SAVE NBT5 FILE

You now have a “.nbt5” file ready to start your upgrade later. If you experience any other problems here, please do not continue and contact your support person to find out what the problem is and how it can best be solved.
You could also do this before you go to the customer for the on-site upgrade.

For all the actions below, you will need to be on-site with your PC during the installation.

- Make sure you know the fixed IP address of the G3 central unit(s), because you will need this later.
- Make sure that the computer you are doing the upgrade with is NOT connected to a switched socket that could fail during the upgrade. (Unless you are working with a battery-powered notebook). After the upgrade, everything will be ‘OFF’:
- All relays - OFF
- All dimmers - OFF
- All thermostats (T-zones) - OFF
- ….
This means you cannot send the new .nbt5 file to the central, which of course will be a must for restarting.

2. HARDWARE PREPARATION

2.1. USE PROSOFT 4

In order to give the centrals (if necessary; see text above) a firmware upgrade, it is advisable to use PROSOFT 4 for this, this can make it easier to have to do a possible downgrade if certain functions that are important to the customer are not yet supported in PROSOFT 5. In 2025, all functions of PROSOFT 4 will gradually also be included in PROSOFT 5, but there are still some exceptions as of May 2025.

2.2. CHECK THE BROWSER

Surf/Browse to the existing IP address of your central(s). This should typically look like this:

The most important thing is that under 'Software' the 'Distro' version 20240906 or higher is shown.
If this is the case, you can skip the following steps and your hardware is OK, otherwise take the following steps to upgrade your hardware.

2.3. FACTORY RESET

There are 3 possible ways to do a factory reset, all 3 end with the same desired result, but depending on the network situation certain ways can be blocked.

2.3.1. Factory reset Method 1: Manual

The manual method is to press both SW1+SW2 for 5 seconds when switching on the power to your G3 central unit.
So first switch off the power to your central unit, then press the SW1 and SW2 keys together and only then switch on the power again. The factory reset procedure then starts immediately. You can therefore release SW1/SW2 after a few seconds.
This method is explained in detail here in this link.

If you have multiple central units in your installation, you must also do this for the other central units.

Attention: the central unit must have access to the internet (via the LAN connection) so that it can retrieve the new firmware data via the internet.

If this method does not work, you will have to use one of the other two methods. If one method does not work, the central unit will automatically restart after 30 seconds, and you will still have the same ‘Distro’ version afterwards.

2.3.2. Factory reset Method 2: using PROSOFT 4

A second method is to start the procedure using PROSOFT 4. You do this by going to the menu “Extra/Central Units” and clicking on the “Factory Reset” button:

If you have multiple central units, you will also have to do this several times.
For this method, click on the “Start normal (From CU to internet)” button.

This method works identically to the manual method, but you do not have to press the buttons on the central unit. However, if your router would block UDP packets on port 69, you will be forced to use the third method.

2.3.3. Factory reset Method 3: with PROSOFT ‘in between’

You start this method in PROSOFT extra/central units/ with the button “Start with PROSOFT in between”

With this, PROSOFT will deliver the firmware file for the central unit to the central unit from the PC on which PROSOFT is located. Please note that PROSOFT must have already had contact with the internet in order to be able to retrieve the firmware file.

Once this procedure has been successful, your central unit is ready to upgrade to PROSOFT 5.

2.4. ADJUST IP CONFIG (AFTER A FACTORY RESET HAS BEEN DONE)

If you have just given the central unit a factory reset, it will be set to DHCP again as before. If you want to set it to a fixed IP address, you can do this now via the browser. To do this, surf to the IP address of the central unit (if necessary, search by pressing the ‘search G3’ button in the Communication/Receive menu).

To do this, enter the following data in the fields above:

IPv4 Addr: the desired static IP address followed by a “/” and then the number of bits that
must be included, typically this is “/24” for 192.168.5.*, but can also be /16 for the network 10.0.*.* (see https://nl.wikipedia.org/wiki/Internet_Protocol_versie_4 -> Subnetmasker)

IPv4 G/W the address of the gateway, usually the IP address of your router, can be seen in the screen above

IPv4 DNS the address of the name server, usually also of the router, can also be seen in the screen above, you can add a “,” (comma) after it and supplement it with an extra name server such as “1.1.1.1”

Now click “Save STATIC”. You will then be asked to enter a “Technical Code”, which is “09876”.

3. PERFORMING THE UPGRADE

After completing the above steps, you are fully ready for the upgrade.
If you decide to return to PROSOFT 4 in the following steps, you can do this by repeating step 2 and performing a factory reset, and then sending your nbt PROSOFT4 file back to the central. See also more details in the chapter below ‘downgrade to PROSOFT 4’.

3.1. FIRST TIME TRANSMIT

Open PROSOFT 5, open the .nbt file and go to the communication menu

Click on transmit, the central will be upgraded and will then run completely on the new PROSOFT 5 package.
It will take about three minutes before your central(s) are restarted and you will see the following screen:

After that, your central will have started up, and you will have to wait a while before it has the status ‘running’. If necessary, do a second Transmit, if you still have red crosses.

3.2. CHECK DIAGNOSTICS

Open diagnosis and check whether you can switch relays and dimmers and such on/off.
Go to the interfaces and check whether they are found.

3.3. SET INITIAL VALUES

Due to the upgrade, all statuses have disappeared, you can now switch the desired things “On” via diagnosis.
Pay special attention to e.g. heating/cooling zones, they will all be OFF. You can easily switch these on via diagnosis and select the desired mode and preset.
Also e.g. flags, process functions, ... will all be off, you may also have to set some specifically here, but normally you should have entered a suitable start-up function there that has already done this automatically for you when starting up. If not, it is still best to do that: PROSOFT – Extra – Options – Options – Service Options – Auto start function.

4. UPGRADING ATMOS

4.1. DELETE/ADD LOCATION

The ATMOS app will no longer work due to the upgrade. On the customer's mobile devices and on the ATMOS-PC app, you must first delete the old PROSOFT 4 location (in the hamburger menu at the top left in the 'Locations' menu), then you can add the location again. This will then be the PROSOFT 5 location.

5. DOWNGRADING FROM PROSOFT 5 TO 4

If there are important functions for your customer that are not yet available in PROSOFT 5, you can easily downgrade back to PROSFT 4.
To do this, take the following actions:

- Start PROSOFT 4 with the most recent ".nbt" (4) file. - Go to the menu “extra -central units” and click ‘Factory reset’.
If this does not work, go to the menu above for the two alternative methods (1 and 3).
- After the completion of the factory reset (can take a few minutes) your central unit will now work again with PROSOFT 4 but without the nbt file.
- You now need to connect PROSOFT 4 to the central unit to be able to do an nbt Transmit.
Restart PROSOFT 4, and go to the menu Communication – Receive – and click ‘configure’.
Now you will automatically end up on the central unit via your browser (see capture below):

To do this, enter the following data in the fields above:

IPv4 Addr: the desired static IP address followed by a "/" and then the number of bits that
must be included, typically /24 for 192.168.5.*, but can also be /16 for the network 10.0.*.* (see https://nl.wikipedia.org/wiki/Internet_Protocol_versie_4 -> Subnetmasker)
Example: "192.168.0.201/24"

IPv4 G/W the address of the gateway, usually the IP address of your router, can be seen in the screen above. Copy it from there.

Example: "192.168.0.2"

IPv4 DNS the address of the name server, usually also of the router, can also be seen in the screen above, you can add a "," and add an extra name server such as "1.1.1.1"
Example; “192.168.0.190,1.1.1.1”

Then click on “Save STATIC” you will then be asked to enter a “Technical Code”, this is 09876.

- Now also enter the IP address in the ‘receive’ menu and ‘connect’. The central unit should now be connected to PROSOFT.
- Leave the screen and send the nbt file to your central unit via the ‘Communications - Transmit’ menu.
- Do not forget to switch ON any important relay outputs, dimmers and temperature zones after restarting the central unit, because after a factory reset all relay and dimmer outputs as well as the thermostats (temperature zones) are switched OFF.
- Reset any OPUS screens you may have by removing the power from the PoE for a few seconds and then switching it back on.

We wish you much success with this important upgrade. We are sure that you can satisfy and surprise your customers with the new possibilities that you can offer. TELETASK will of course add new ones regularly in the future.
