Boiler installed Nov 08, and I think this unit was probably installed at the same time, so a bit over 5 years
Yes, been working reliably until last few weeks when it has been a bit temperamental. Since two days ago, nothing
Boiler serviced a couple of weeks ago. Boiler working okay
What is the other thing you think it could be?
Are there any test buttons on the back of the transmitter that can be used to try and reactivate it?
Tried that already... :-(
Are we looking at a unit replacement then?
you are giving conflicting advice. Which should I do?
You say "I would have the tech come back, as this could be a bad sensor or an air adjustment is all".
You also say "it sounds like its time for a new controller.I wish I had better news for you I really do, but at least you know for sure what the problem is".
Mmm...what did we do to test for a bad (flame) sensor or air adjustment? How have you now ruled out these possibilities?
If you think the only option now (apart from a whole new unit) is to make a replacement part, what replacement would I need to make and with what materials?
The boiler was serviced a couple of weeks ago, so I don't suppose the control board at the boiler needs attention.
I don't know (and you have not said) where the flame sensor is - is this part of the siemens unit or part of the boiler? If part of the boiler, I suspect it should be okay (as boiler serviced recently). If part of the siemens unit, can you be precise about what I need, where I might get it and what I do with it once I've got it?
I simply do not understand what you mean when you ask, 'do you have a meter for testing?' Is that a piece of kit to test something on the boiler or the siemens unit?
Right. Tried that.
Green light on Siemens unit now solid green. Yellow light gone out. But no sign of life from the boiler :-(
Please, what does this tell us?
Okay, so this is the control board that is part of the boiler, right?
If so, should the servicing guy have picked this up 2 weeks ago?
Does this mean that the siemens thermostat unit is okay and not in need of replacement?
How much should I expect to pay for a control board?
Are they easy to get hold of?
Is it easy to replace?
Could I do it myself, or should I get the servicing guy to come back and do it?
Can you please tell me precisely what part I need to order (order ref or code?) and how much I should expect to pay for it? Thanks
I might well get the guy back to install it...
In case it is relevant, the boiler is a Ferroli Optimax HE31S
This is a boiler part, right (Ferroli)? Not a thermostat part (Siemens)?
