Hi - wonder if someone can give me a bit of information. Following a visit from a W Bosch technician today the 'eco' button on my 40cdi conventional boiler (not combi) has been lit up. When I look this button up in the manual it just says 'not applicable'. It wasn't lit before the visit, it have pressed it and nothing happens.
I just wondered what the eco button is and what it is supposed to do as I can't find any information about it.
Thanks
