Customer Question

fan balanced sealed sytem vaillant probably 12 years old - struggling to find that boiler number!

At the front of the boiler it has symbol which is a 'hand with a finger pointing' not sure what this is.......? the light goes red? What does this mean?
Also playing with the settings there is a list saying d that ican change from d1 up to d99 . What is this for?

Hi I am sorry to hear that, I think I know whats needed but yes you are correct, we need to find the model # ***** be sure and to order parts.
Please inspect it carefully but you may need to remove the cover(s) to see where they placed that.
Valliant is good for putting these model #s in weird places.
Let me know if you locate that or even the serial #.
Thank you
