Valliant boiler manual required

[sp33dy]

Hi,

Can anyone identify this Valliant boiler type (see picture). I would like to get the manual in order to check the programming of it. There is no hint as to a model number. I've searched around, but everything I find seems to have a digital control, where as this has a manual timer. I'm not sure where else to turn.

I've also got a drayton t45 thermostat on a wall. The boiler doesn't seem to care about the temporature setting (Ie always on, but I know it's wired up.. Recent builder moved.. ggrrr). Is it possible it's wired round the wrong way? I've take off the wall, it has three wires. The diag has:

Pins:
1 - N
2 - L
3 - 1
4 - 2
5 - 3 Call

To be clear, here is a picture:

I'm colour blind, but N appears to be blue, L appears to be red (or brown) and 3/Call appears to be yellow.

Any idea which two wires I need to switch around?

Thanks and kind regards

Doh.. Sometimes the simplest answer is the one I've overlooked. I'll ping them an email now...

Any thoughts over the thermostat wiring? I'm gradually building up my knowledge. Apparently all it's doing is completing the circuit, in order to allow/disable the boiler. I get that. I see that the L is live and has a voltage (purely from checking there is one, not knowing how much).

Kind regards

you only need to use 1 and 3 for switching,I dont normally give out electrical information because if there is chance that you dont know what you are doing exactly then you may damage the PCB on your boiler

Given what you've said. I know myself around wiring, but not to an expert way. Very odd. I've just clipped the thermostat front into the wall mounting and it is now controlling the boiler again!!! How exciting. Sort of fixed. Is it possible that it's become faulty? After all, we've had it 10 years. Or is it possible that the builder hasn't clipped it back in right? Although, I don't think that can be the case..

>David, thank you.

you are probably right ,it wasn't making contacts properly.Hopefully it should behave now


Good luck
