Hi all,
On Tuesday 27/08/19 there was a thunderstorm which hit the electricity grid in our area killing the power to our house and some of the neighbours also. (They have reported some appliance damage caused by this).
I can see on the log (also via stokercloud) that it reported some abnormal power levels around the time of the storm, and when I started the furnace up after the storm , the "O2-styring" method changed from "JA" to "VIS"
I initially thought my lambda sonde was toast, so I bought a new one. This however was not the case since I was not getting a reponse with readings, or when trying to calibrate. The new sonde was also cold and not heating up.
I replaced the fuse on the expansion print in hope that it blew with the power surge. This seems like a partial success and appeared to be a problem. The sonde is now heating up, but i still do not have any o2 readings, or when I calibrate i get the below message (see attachment).
The message I get via stokercloud: Info: Ingen forbindelse til udvidelsesprint, kontroller dine forbindelser eller indstillinger.
I have checked all cables and wires to ensure they are correct (based on
https://www.nbe.dk/wp-content/uploads/2015/08/RTB-Manual-V7-DAN-07.04.2016.pdf) and connected. Also worth nothing all this was fine before the electrical storm.
My next stop is to try getting a replacement print, but as they are fairly expensive, this is a last resort.
Thanks and regards.
