Smoke detector Installation The YKN2Open board (A1) indicates smoke faults with a 4-5 flashing sequence of the red LED. If thermostat DPC-1 is fitted, the incident is indicated on the screen where the time is displayed along with fault code 45. Once the presence of smoke has disappeared, the thermostat must be manually reset and the YKN2Open board (A1) reset to delete the incident.
