2477D dimmer not responding to 'all on' or 'all off'

[ltgcc]

model 2477D rev 8.2. controller is a 2440. Dimmer responds to assigned button (2). On, Raise, Lower, Off. Does not respond to 'all on' or 'all off' buttons. 6 other dimmers and two wallswitches installed and assigned to same controller and all others respond to 'all on' and 'all off' as well as their individual buttons.

Dimmer has been detached and re-attached multiple times, as well as factory reset multiple times. Still no joy.

thoughts?

thanks.

The all on/off command was removed from newer insteon devices. It sounds like you have older devices that still respond to that command which is why they work
