SOURCE: ferroli optimax HE 31C boiler

Setting time is not in manual that we received, however, we did get a separate sheet: Buttons top left-right are A - Clock adjustment B - Operating Mode selecting C - Override Buttons bottom left-right are: D - - E - Programmes F - +
To set clock: 1 - Push A 2 - When the DAY and the CLOCK icons on the LCD are flashing use + and - (D and F). You should set the day of the week (1 = Monday, 7 = Sunday). To confirm the day press A. 3 - The HOUR and CLOCK are flashing use + and -. Confirm with A. 4 - MINUTES and CLOCK are flashing use + and -. Confirm with A.
My LCD is not working correctly, so I have to press the screen gently to see what icons are displaying. Annoying.

Fault code f35 on ferroli optimax he plus 38 c


You simply need to get an electrician to check the power supply to your property, with a frequency meter if it tests OK then you will probably need to replace the board on the boiler, it has to be said that the incoming mains frequency is set by the supply system and generally cannot alter but some local conditions can have an undesirable effect, any good electrician will have a frequency meter on his van and will take only a few minutes to test.

Ferroli optimax he 31c. brand new system will only heat 3 of 8 rads. boiler on 90c will only burn for 15sec then D2 shows and it cuts out. Why??


it is either your pump is not running or blocked [ debris from installation ect ] or your diverter valve is stuck partially open allowing a little water to pass into the heating system [ usually first rads on system ] it runs for a short while and cuts out because your overheat stat is kicking in because of poor circulation [ it is only running around the primarys in the boiler where it quickly reaches the over heat limit ] temp tends to rise approx 1 deg per second a clear indication of circulation problems.

Do you know where I could get the instructions for setting the clock timer on my optimax he 31c


I sent an e-mail to technical@ferroli.co.uk telling them that my Optimax HE 31 C
manual didn't include instructions for the timer, and received a manual via e-mail within minutes.

You probably won't get a reply during the weekend though.

Good luck!

I have just tried to run my ferroli optimax 31c boiler. The boiler fires up, but then displays a d2 message and the radiators do not heat up. Any ideas what causes this problem and how I can solve it...


D2 is not a fault what that means is delay and 2 refers to CH which means the boiler has gone into standby mode. you need to check that your CH circut is open, there is a filter on the return valve into boiler make sure this is not blocked. If this is blocked the water is just going though the boiler by-pass so then the boiler thinks its up to temp. hope this helps

Problem with heating on ferroli optimax 31c


d2 is the code symbol for delay after central heating. and is not a fault code.. however if this is coming on then stopping the operation of the boiler then it usually points to a sticking diverter valve.
