How do I set the heating timer on a Ferroli Modena 32C HE boiler?


I did a Yahoo search for "set heating timer on Ferroli Modena 32c HE boiler" and got this -

http://www.ferroli.co.uk/brochures/Timer-HE-013001X0-Instructions.pdf

If you can get to that site, it will let you download a PDF which seems to answer your question.
I copy/pasted the hyperlink, but you may have to enter is yourself. My last hyperlinks did not work.

Ferroli boiler optimax he 38 c.Powers up ok,no hot water,no error code.Think its an ignition problem.Heating flame not showing?????


Is there an error code? If not the flow sensor for the hot water could be faulty. Also if you've had a power cut depending which model of Optimax HE you have, you sometimes have to tell the boiler it's a Combi, as they have a generic Pcb fitted which is also used on the system only boilers.

The wifi connection from worcester boiler to room thermastat Honeywell Cm921 , boiler not receiving signal


Can't help you directly, but Honeywell will have user instructions on their website.
It's something like holding the 'stat within a metre of the boiler when the batteries are inserted. Best to RTFI.

Why does my Ferroli HE31C keep switching off code A3.


Here you go, page 30, sounds like it's overheating, possibly a problem with the boiler stat or lack of circulation in the system. http://www.ferroli.co.uk/Product_Documentation/Domestic/Optimax_HE_31_C_Manual.pdf

Ferroli boiler error code A3


boilers need a certain amount of water pressure to operate as specified--there may be a pressure regulator valve, allowing a certain amount of water to your boiler, and when water is drawn elsewhere, there may not be enough getting to the boiler---this is one possible solution, but there are easily 20 more, and that is where a trusted plumber is worth it's gold...very difficult to diagnose most plumbing problems without being onsite
