[M&S][Nortek][MC350A] - REL5 flashing & time flashing
Last Updated 5 years ago

This actually means RELS which stands for release.

There is typically a bad room station that has a broken button, or button stuck.

To troubleshoot:

  • remove all black wires from the master unit.
  • Any display of RELS or clicking sound should stop.
  • Add back the black wires one by one until the issue of RELS occurs again.
  • If so, do not attach this wire and hook up all remaining wires.
  • If the user wants to know which room station this is,
    • go from room to room and press the listen button.
    • If the music is muted, the station is good.
    • If the music continues, this is the bad room station.
  • Unfortunately, these room stations are no longer available. So we may have to repair it if that is your option.
