Boiler will not fire up

[Boomer48]

Hi all,
Cant get the boiler to fire up, thus no heating. Messed a bit with it earlier today, and re-programmed the Danfoss controller, and it worked.
Heating was on, and then went off on time, but didnt kick in on the next cycle. Tried setting temp up high on thermostat, and turning electrics off then wait, then on. No Joy.
I am just a regular homeowner, and ideas?
regards

OK so now after mulitple tries, the system has fired up, but now I am sceptical if it will operate on the timer as set. All the relevant lights come on i.e auto on auto off, all day on all day off. do I need to change the Danfoss Programmer? Any thoughts?

Just as above

What boiler, and is there motorised (zone) valves?

Hi there,

As above check zone valves if fitted, move the lever across & it should return under spring pressure to original position.

You will hear it motorising back as the lever returns.

If you have set the programmer timings & it does not come on at designated times see if the programmer has a +1 button or advance button which gives a manual override input & boiler should fire up if room temp is below desired temp on stat (if fitted).

My guess is on the programmer as i have had a few that have gone a bit haywire BUT always check that you have new batteries fitted if it is wireless & that it is paired with the boiler,

Thanks,

Andy

Thanks for the reply Andy, I managed to get system working this morning and have re-programmed for on all day, but now i have to monitor it to see if it cuts in and out.
I have an 'advance' button on the programmer and will try that also.

Have you changed the batteries and tried re sinking it

I have a couple of customers who despite me putting in a good rf programmer/stat with tpi that still leave it on a constant 10 degrees setback temp & then manually override it via stat to 19 - 20 degrees when they are in the house & are completely happy with that.

It defeats the object of fitting/programming these type controls but at least they will have low level heating through any cold spells or when they are away for a few days during the winter.

During the spring/summer/autumn they find the boiler will only very rarely kick in if temps drop enough.

Just another way of looking at it & if you find it works for you on constant setting with manual inputs for temp control then all is good,

Thanks,

Andy
