Hi,
I have a Vaillant Turbomax 282e boiler. The timer is one of the green mechanical jobs, and it appears to have a fault - when on timer, the heating never goes off when it's meant to; if the timer says on from 8 to 9pm, I will find it still firing at 9.30, showing no signs of stopping. when it is in this state I can "reset" by powering off the boiler, and sometimes just by moving the timer to the off position, but that doesn't always work.
So I found a replacement timer on ebay... I'm not sure it's the timer, I imagine there might be other causes, but I found what looked like a good replacement, a digital version which if it worked would be an upgrade. It was only £25 so I took a punt.
Sadly, I am a prat.
The new timer is for a Thermocompact 282e, and despite being the right shape and colourscheme, the wires are different (why Vaillant? Why the same boiler number?).
The old timer has a 4-wire white ribbon cable which plugs into the PCB.
The new one has heavier wires that have to be separately screwed into a connector block. The wires are blue, brown, black, red, white and grey. There's a secondary loom which extends the black/brown/blue, presumably a power circuit for something else.
Question. Is there any point at all in trying to make this fit? I assume not, and the seller has agreed to refund, but I thought it might be possible and that someone here would have a definitive answer!
Many thanks, sorry for being longwinded.
