help needed please...

Hi there...

I hope someone is able to help, it's needed urgently......

I have an old Valliant Combi boiler with a British gas EMT2 timer fitted and a room thermostat downstairs.

The room thermostat dated to the 60's so I brought a Honeywell T6360 to replace it. When I took the old one off I found a red,black and earth cable, and a single red on it's own. I was advised..(hmm) to firstly try wiring the thermostat without using the single red. I did this but the boiler wouldn't fire up. I was then advised (hmm) to simply connect the 2 red wires together. This had the desired effect the boiler sprung to life... however when I lowered the thermostat past the switching point the trip switch clicked.

When I turned the power back on I found that the boiler wouldn't fire up again. There is a light on the timer and I can hear the clock mechanism working. I have since put the old thermostat back on and still the boiler wont fire up.

I have now been advised, by someone else!!.. that I dont really need the thermostat as the house is only small and needs to be cranked up to make any difference anyway, so does anyone know first of all how I would I remove the thermostat from the circuit?? Does anyone know how they are wired into this timer..??

The other thing I need to know is is there a fuse in the timer or boiler that will have blown when the power tripped?? There is obviously power getting to the timer as the mech and light is still working, it just doesn't seem to be getting out the other side...

Your help in this is very much appreciated.!!

Here's the help you need;

Stop taking 'advice' from the people giving it, they obviously know buugger all.

Don thick rubber gloves and rubber soled shoes.

Keep experimenting by connecting different pretty coloured wires to different terminals on the timer.

Keep your fingers crossed, and try not to touch the boiler casing or any pipework attached to it.

After one week, or in the event of your local electrical suppliers stock of new fuses becoming full depleted, come to your senses and get a Corgi bloke in!

namsag.. thankyou!!! for your help!!.. I've not done it yet.. but will give it a go, thanks... Do you have any knowledge of where I will find the fuse in the boiler.?? I'm a bit apprehensive of taking the cover off it, but don't anticipate it being a problem if I only need to replace the fuse...

Would there also be a fuse in the timeswitch too..??

Thanks again

Some vaillant fuses are on the boards others are in little plug in holders so depends on model.
No fuse in timer usually

Thanks for responding in such a helpful way!!!.. unlike some of the sarcastic answers I have encountered on this forum before!!...

Thanks!

Dont worry Agile will be along later to oblige you.

Turn power off before you open as there is still a live to boiler even though its not working
