Not sure what the LED code is for the issue but I have recently come across an after hours override switch that has a constant red blinking LED light illuminated on the front of the cover. Not too sure what this issue could be. When I go to override the current setting, by pushing either the on or off, both the on and off switch flash green and nothing happens to override the current setting. Is there a list of what these LED colors/pattern of flashing mean for troubleshooting purposes?
Lights flashing down the station when pressed indicates an unbound station. Is this a Unison Legacy system? If so, try manually binding the station from the processor. Or, remove it from the wall and power cycle it.
