Vaillant Sensohome and fault codes.

[rgregson23]

Hello All
I have an ecotec 630 with Sensohome controls. Should the fault codes shown in the boiler also be reflected in Sensohome control? All appears to be working ok but the Sensohome has a fault code relating to the outside sensor (F521) which I can't seem to clear. The sensor is working ok as I see the OT on the panel.
There are a couple of fault codes on the boiler but I don't see them on the control. Is this expected?
Thanks for any advice in the past.

What are the fault codes on the boiler?

I think it will show an actve fault but not history

Hi Chris sorry for the delay in reply. There were several codes, but they seemed to have cleared themselves when I looked again. I remember the one F,78 about hW sensor. They are gone now so perhaps I was being a bit hasty.

F78 mentions the incorrect configuration with accessory, so maybe this is why you’re getting faults?

many thank Chris. I will try pairing the outside sensor again to see if it clears that one. thanks again.

well that one has gone as well. It's for the NTC sensor.
