You would first need to download the latest firmware from the product page of the specific amplifier. Scroll down to the bottom of the page until you get to the “downloads” section.

M4800           M4840          M6400          M6800

Once you have the latest firmware saved to you computer, log in to the web interface of the M series amplifier and navigate to the Device Configuration tab. In the bottom left corner of the page, you will find the firmware update button.

The amplifier will then begin updating the firmware. There will be a percentage ticker showing progress of the update.

Once it reaches 100%, the amplifier will reboot, it will take about a minute. At this time the web interface will be unresponsive. After a minute or so, either refresh the web page, or click on a different tab within the web interface and it will re-load the page.

You will be able to confirm the update by checking the revision # in the top right section of the configuration tab.

Firmware update instructions: Concert XR 4/6/8 receivers and Maestro X7/X9 processors 


Dirac files:

Firmware updates clear any Dirac calibration settings that are currently uploaded to the XR receivers / X processors. Make sure you have access to the saved Dirac calibration file on your computer so you can upload back to the receiver/processor once the firmware update has completed.

Store a secure backup of the receiver or processors settings:

Front Panel: Press and hold the MENU button on the front panel for about 4 seconds, the Engineering menu will be displayed. Scroll down to and select Store Secure Backup > select Enter Pin, the default pin is 0000, press Select. 

To check the current firmware version of your receiver or processor:

Press and hold the front panel INFO and DIRECT buttons together for 4 seconds. The firmware version will be displayed as a HOST/IAP number, for example, 1.07/09. The first number is your firmware version.  

USB DRIVE FORMAT: the USB drive should be formatted for Windows FAT or FAT32. To speed up the update process you may want to use two properly formatted and empty USB drives since the USB update process requires that you load the Host and Network update files separately, you can put one file on each of the two drives [Refer to step 7 below].  

Airzone systems normally compose 3 types of elements: smart thermostats (one per zone or room), air diffusion elements (grilles or motorized dampers, electrovalves and individual units) and a main control board that analyzes all the information, sets the operation point of all production units and regulates the performance of the diffusion units.Universal WiFi device offers compatibility for thousands of Air Conditioner models, it only requires an Indoor Unit that has an IR receiver working with a standard Wireless Remote Controller.

Here are the two models of gateway needed to the integration with Control4:

To be installed in the box:

DIN Rail:

You need a driver for each zone. Download

There is no master/slave driver set up required.
The driver is smart enough to adjust the UI depending on the zone’s capabilities that you connect it to.

The installer will provide you with the system and zone number for each thermostat.


  1. Confirm that you have the System and Zone number for each thermostat (provided by the Airzone installer)
  2. Add Airzone driver to project.
  3. Enter IP Address in the Properties tab and click Set.
  4. Enter TCP Port (default 3000) and click Set.
  5. Enter the System Number and click Set
  6. Enter the Zone Number and click Set
  7. The driver will now configure itself for the specified zone and update the Control4 UI as required
  8. Bind the room Temperature and Temperature Control to the desired driver
  9. Press Shift+F5 to refresh Navigator

DeBrick recovers 2G, 2GΩ/3G, and 3G devices that have had their firmware update interrupted.


Required Hardware

  • Just Add Power debug cable
  • PC with serial port or USB-to-serial adapter
  • Wired network connection
  • Power supply for Just Add Power device
    • 5-Volt, 2-Amp for 2G
    • 5-Volt to 23-Volt, 2-Amps or less for 2GΩ/3G and 3G


Debrick physical connections
  1. Make 2 physical connections between the Debrick PC and the Just Add Power device:
    • CatX network cable directly from PC to network port of device
    • RS232 debug cable connected from PC to white 3-pin port on bottom of device
  2. Leave the power cord disconnected at the beginning
  3. Select the Device Type for the unit being recovered
  4. Select the Serial Port for the RS232 debug cable connection and remove power from the device when prompted (if not already removed)
  5. Make sure the debug cable is connected, then select the box labeled Connect Bricked Device Directly to Computer via RS232 Console Port.
  6. When the popup message appears, apply power to the device. The green bar at the bottom will move to RS232 Connection Established.
  7. Make sure the network cable is connected directly between the PC and Just Add Power device, then select the box labeled Connect Bricked Device Directly to Computer Via Ethernet. A prompt will confirm.
  8. Select the wired Network Interface connected to the Just Add Power device.
  9. Select the box labeled Begin Recovery Process and allow the process to run to completion without interruption. DANGER: Interrupting the process before completion will most likely result in an unrecoverable unit.
  10. The Debrick process will take between 5 – 8 minutes depending on the unit type.
  11. When the Debrick process is completed, a prompt will ask if you want to update to the newest firmware (Debrick does not always contain the newest firmware). Choose the option needed.
  12. The unit is recovered and has all settings that were applied to it before the unit became damaged.
