Z Grills Controller Software Update

Most Z Grills models in Australia have a controller board with a plug to allow the software to be updated using a special dongle.

If you received a software dongle with your new grill please click here.

Do I need to update?

If you have been using your grill and it is running well, there is no need to complete an update. If a software update pack was provided with your grill then you need to complete that before burning in. Click here for instructions.

Only controllers with the small white 4 pin plug on the rear of the controller panel (as shown below) can be updated. See the update process instructions below to safely get access to the controller to check if your controller has this plug.

Software Versions

Below is a summary chart of the grill models, serial numbers or model feature for identification and corresponding software versions.

You cannot download a file and complete the update yourself as it requires specialised software and update dongle to complete the update.

Update dongles types

There are two types of dongles which are used to to update the software on the controller without the need for a computer.

STC TYPE DONGLE

For any software with STC in the name.

GD TYPE DONGLE

For any software with GD in the name.
May come with or without the grey ribbon cable.

GD dongle update process

First check the Software Version chart in the section above to see if your grill is eligible for an update. If it is, and you would like to complete an upgrade, double check your controller to make sure it has the update plug.

Got a new Z Grills 7002B or 700E-XL?

If you received a software update dongle in grey plastic satchel together with your grill, please
complete the update before burning the grill in.

Follow the instructions below.

The update can be completed before or after the grill has been assembled and used. If the grill is NOT yet assembled, do the software update first.

Follow the step by step instructions below.

STEP 1. Make sure the controller knob is turn to Shut Down, power switch is flicked up to the OFF position and grill power cable is unplugged (not just turned off at the wall socket).

Leave the grill unplugged for at least 2 minutes before starting STEP 2.

Unplug power

STEP 2. Undo the 2 screws on the front of the controller.

STEP 3. Tilt the controller forward and look for a white plug on the left hand side of the circuit board.

STEP 4. Plug in the cable with the clip to the outside (left side). Push down until it clips into place.

STEP 5. Plug the standard USB cable into 5V power (USB battery pack, USB phone charger or power board USB plug).

Plug the square end of the USB power cable into the dongle.

STEP 6. Watch the light on the dongle.

The light will change colours in the following sequence.

  • Quick green light
  • Solid orange/red light for 3 to 30 seconds (copying process)
  • Quick green light
  • Quick orange/red light
  • Solid green light (copying complete)

Once the final solid green light is on, the copying process is complete and the power cable into the dongle can be unplugged. Click here to jump to Step 12

If the light didn’t complete the sequence outlined in Step 6, follow the steps below.

STEP 7. Carefully push the controller back into place with the white cables still attached. Do up both of the screws. Keep the USB power plugged in, so the green light is still showing on the dongle.

STEP 8. Only once both screws are back into place and with the power switch in the up (OFF) position, plug the grill into into power.

The controller must be put back properly with both screws done up before the grill power cable is plugged in. Plugging the grill into power with the controller in a loose position can result in a short that will blow the fuse and potentially damage the controller.

STEP 9. Flick the power switch on the front of the grill down to the ON position. The dongle light should turn from green to orange and begin the update process.

The light will change colours in the following sequence.

  • Green light
  • Solid orange/red light for 3 to 30 seconds (copying process)
  • Quick green light
  • Quick orange/red light
  • Solid green light (copying complete)

STEP 10. Once the update is complete, unplug the USB power supply from the dongle. Flick the controller power switch up to the OFF position, wait 10 seconds, then switch to the down ON position.

The display should flash 700 then 813 for 700E-XL grills, and 702 then 812 for 7002B grills. This indicates that the controller has been successfully updated.

STEP 11. Unplug the grill power cable, then wait at least 2 minutes. Next, continue on to Step 12.

The grill must be unplugged from power for at least 2 minutes before removing the screws on the controller!

Continue on from Step 6 or 11……

STEP 12. Squeeze the top of the plug firmly to open the side clip and pull out.

STEP 13. Carefully push the controller back into place and do up the screws.

The controller must be put back properly with both screws done up before the grill power cable is plugged in. Plugging the grill into power with the controller in a loose position can result in a short that will blow the fuse and potentially damage the controller.

STEP 14. Plug in the grill power cable and flick the switch on the controller down to the ON position.

The controller should flash the grill model (450, 702 or 700) and then the software version, for example “813”. See below.

Controller model and software version on Z Grills smoker LCD display

Confirm if the version displayed matches that printed on the dongle. If it does you have successfully updated the software. Great job!

If the display does NOT show the updated software version, or is blank, repeat the process.

If it still fails to update correctly, please contact us.

STEP 10. Please wrap the dongle and USB cable back up in the bubble wrap, put in the supplied Australia Post satchel and place in a post box (or give to the local post office) to send back to us.

Please send the software dongle back to us. Cheers! 👍
