What it means

Duplicate device address error on the communication network.

Possible causes

Two indoor units set to the same address Incorrect rotary switch or DIP settings Commissioning process not completed correctly

Suggested fix

Inspect address settings on all indoor units and assign unique addresses according to the design; power-cycle and reinitialize communication once addressing has been corrected.
