I just removed my Lennox Y0349 thermostat to use a NEST thermostat.

I just removed my Lennox Y0349 thermostat to use a NEST thermostat. I don't see a spot on the NEST will take the "L" wire previously on the Lennox unit. Is this a problem?
Hello,

My name is Billy.

This is not an issue. The L is no longer needed and can be taped and tucked away.

It is an older terminal for indicators no longer used in the industry.
