This article provides comprehensive instructions on diagnosing and troubleshooting issues with Application Controllers and Field Controllers, including LED behaviour and switch press schemes. It describes LED light patterns and what they indicate, such as the controller's operational status, errors, and modes. The guide also provides detailed instructions on using onboard switches to execute certain commands, such as toggling lamps, forcing Cloud Connect, rebooting the controller, and more. The switch press schemes are divided into two sections, depending on the software version (prior to 1.9.160 and 1.9.160 onwards).

Please note that Room controller / LCM products do not feature onboard switches or LEDs.

LED Behaviour

Application Controllers 

Application controllers (pro, standard and pro 3) have two 3 colour (red/green/yellow) leds which are also switches.  On Pro 3 products, there are three banks of ON/OFF (1 bank per controller) and a single STATUS LED.

STATUS remains lit if the controller is powered

ON/OFF and RESET slow simultaneous flashing orange/yellow  - Controller is starting up, addressing or committing changes to the bus

ON/OFF intermittent flash green - Dali commands are being transmitted or received (normal function)

RESET solid red - There is a Dali short or no power supply may be connected

ON/OFF and RESET alternating green - device is in bootloader

If the controller is alternating between bootloader and startup LED modes, the device may be boot looping (failing to fully boot by continuously restarting).  In this situation, the controller may need to be scheduled for a further update to remedy this.

Field Controller

Found under a removable cap that also houses the ethernet connection, Field controllers have 2 buttons (ON/OFF and RESET) and adjacent LEDS.  These LEDS are single colour.  ON/OFF is green, RESET is red.  

ON/OFF flashes with wireless traffic 

RESET remains solid red if there is a fault with the wireless interface (contact support)

ON/OFF and RESET alternating red and green - device is in bootloader

Switch press scheme

Switch pressing was updated in 1.9.160

Prior to 1.9.160

ON/OFF Functionality - Application Controllers Only

Press ON/OFF for less than 2 seconds - Device will send either RECALL MAX and OFF (toggles between)

Press ON/OFF between 2 and 10 seconds - Device will run a broadcast IDENTIFY scheme.  Can be pressed again to stop.

RESET Functionality - Application and Field Controllers

Press RESET for less than 2 seconds - Force Cloud Connect (unlikely to be needed)

Press RESET between 2 and 5 seconds - Reboot Controller

Press RESET between 10 and 15 seconds - FACTORY RESET - do not install where RESET may be held on!

1.9.160 Onwards

ON/OFF Functionality - Application Controllers and Field Controllers

Press ON/OFF less than 2 seconds - Device will send either RECALL MAX and OFF (toggles between)

Press ON/OFF between 2 and 10 seconds - Device will run a broadcast IDENTIFY scheme.  Can be pressed again to stop.

RESET Functionality - Application Controllers and Field Controllers

RESET has been reworked as a function button.

To activate a RESET function, keep RESET held down while pressing ON/OFF a specified number of times as determined by the required function. Once done, release RESET.

Here's a brief guide on the number of presses for each function:

• Press ON/OFF twice: This forces a Cloud Connect, though this is unlikely to be required.
• Press ON/OFF three times: This reboots the Controller.
• Press ON/OFF four times: This forces a fallback to DHCP mode for this boot only (reboot to revert back to original network configuration).
• Press ON/OFF seven times: This initiates a Factory Reset (confirmation is required).

If the press count is successful and does not require further confirmation, the green LED will blink as many times as you pressed ON/OFF, repeating this pattern thrice. For instance, for four presses, the green LED will blink four times, pause, blink four times again, pause, and then blink four times once more before returning to its normal state.

If the press count does require confirmation, application controllers will have their orange LED flashing the same number of times. Field controllers, on the other hand, will not show LED activity but will be ready for the next input.

For actions like rebooting or factory resetting, the device might begin the process even before the LED flashes appear. However, the device will exhibit signs of having reset afterwards.

If an incorrect press count is input or a timeout happens, a red LED will flash to match the number of presses (repeated three times). You can initiate your next press count after the red LEDs have finished blinking.

Confirmation of a function

If a function needs confirmation (currently only required for factory reset), after executing the necessary number of ON/OFF presses and releasing RESET, the controller will ask for an additional confirmation step. This step involves holding RESET down again and pressing ON/OFF ten times. Release RESET after you've done this.

A failure to input the required number of confirmation presses will also be indicated by the red LED flashing, similar to the indicator for an incorrect initial press count.

You are able to begin confirmation before the orange flashes have finished, they are for visual feedback only.
