U10002_1F on/off after hours override not working!!!

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?
