NTI TFTN Boilers - Fault Codes and Troubleshooting

[@cheers0521]

Any thoughts regarding my NTI Error Code ER3? Here's a brief video from my TH-cam channel showing the issue. th-cam.com/video/w5e64CHCTeU/w-d-xo.htmlsi=7HizlIw-k7deBqL9

Er3 is often caused by a damaged Out door sensor or wire conneciton on the top of the boiler, or the water temperature sensor is failing. Your best bet is to get infront of the unit and talk with tech support.
