The VFLEX LED is an essential feature for indicating its status. Full documentation of the status is located here.
Many times the LED indication is useful however in one particular case, it can be disruptive.
When everything is working properly, VFLEX is perpetually showing a Green LED indication. This “light pollution” could be irritating while sleeping or when trying to have other ambiance in your home. For this reason there is a configuration feature that will allow VFLEX to continue to function as normal but turn off the LED when it is in the solid green state.
If Status changes, the VFLEX LED will turn back on and display the new status.
Any other state besides Green will continue to be lit to get your attention.
For example, if there is a voltage tolerance error, the LED will turn Solid Red and remain Solid Red until the error is cleared.
