you likely did not set the dip switches yet for remote thermostat.

If you want warning lights you can go ahead and and hook up L

Also the dip switches ans wiring are covered in the tech manual HERE

did you read the tech manual I sent you link of?

Expert:  BillyHvac replied 1 year ago.

Looks like L is (LS) and not needed anyway for is a building management feature.

The dip switches are shown on page you need the manual link again?

It is not to 39 has pictures of where the dip switches are and what they the remote/thermostat dip switch. It must be set to off.
