    This should be easier than it is!  The old boiler had a lever which re-pressurised and was obvious. I won't touch the black key, we'll just have to wait until an engineer calls me. 

    Thanks for all the suggestions so far, I really appreciate it.
    It is easy. The boiler doesn't come with an attached, keyless filling loop as standard so rather than fit one your installer has fitted an external filling loop instead. The instructions on page 7 of the operating instructions show exactly what you need to do in this instance, just turn the key. However, if you're not comfortable doing it then that's fine also.

    Personally I'd more concerned as to why it's dropped pressure so much.
    The boiler doesn't have the key shown in the manual.   I'll speak to the bloke at the heating company about checking for a leak tomorrow.

    The heating engineer has just phoned, the black key in the blurred photo is the one to use so I've now got the bar back up and, with a bit of luck, the system will reboot in about 10 mins or so.

    Once again, many thanks.

    Fig. 4 on page 7 represents what you have, and the key/handle is shown there.

    Thanks, I can't recognise it as such, sorry.  It look rather different to the configuration I can see.

    Now the remote has lost connection and there are no instructions!  I hate technology when it's not working or explained properly.

    What controller do you have?

    It's the Comfort RF2 - the engineer rang me back to talk me through repairing it, however it stubbornly refuses to do anything.  I've found the manual for it and tried everything there, no joy.  The engineer is going to contact the office to arrange someone to come out.  Meanwhile we'll not freeze today, the temperature has climbed to 5 degrees and DM is okay in bed and she has a portable convector heater if needed.  It's just annoying. 

    Thanks again for your efforts and suggestions.

    The receiver has a button below the indicator light? That's used to 'pair' the two items, but also acts as an 'override' if the stat stops working for some reason.

    Is the light flashing to indicate a connection problem? That's fine. If you press that button ONCE and briefly (less than 3 seconds) it'll turn your boiler on. The light should also come 'on', but just flash 'off' briefly to indicate it's in override mode. You can now control your house heating via each rad - turn the TRVs to what you want to have the room snug. If you want to turn the override off again, just press that button - once and briefly.

    To 'pair' the two, you need to do other stuff - it's in that doc above...


  • Oh, and whenever you repressurise your boiler, keep a steady eye on the pressure gauge and STOP when it reaches, say, 1.2bar.

    DON'T let it go right up near 2 bar or above.

    Happily the heating engineer came out after all - DM is registered with them as both elderly and vulnerable.  He couldn't understand the fault but fiddled around enough to fix it.  The connection was showing a zero bars, now back to 10.  Boiler fired up again and working, heat coming back to the radiators and the house will soon feel cosy again.  Phew!  It's been a long haul.

    Once again, thanks for all the suggestions.

    I wonder if the following had anything to do with the problem 😉

    I touhed the green thing, it turns yellow'ish and beeps though nothing happens.  I've turned the boiler off and touched the now blank thing.

    The receiver is plug and play and it's entirely possible you may have knocked it out slightly when trying to reset it.

    Everything is entirely possible! My own home doesn't have such sophistication, only a necessary wood burner so it's all new to me.  Now we are back to being toasty. Impressive service from the company.
