I have finally got my FBH (Fuel burning heater.) fitted and fully functional. So, in preparation for the lovely English winter, I thought I would go about fitting at timer.

I searched Ebay for a "12V Timer Switch" and there were loads of cheap ones from China (no surprise).

I ordered this and it came in just under a week:

Image

It was less that £7 delivered, so if it was rubbish I hadn't lost much. Its got manual override for on/off and auto functions. The timer is 7 days and there are about 15 on/off functions, so plenty to play with :D

I wanted to put it somewhere out of sight, so decided to put it in the cubby under the armrest.

First thing was to take the cubby out, 2 torx screws and a bit of a tug at the front and it was out.

Image

I decided to make a cardboard template first, so that the fit was right.

Image

I then transferred this and cut out some 1.2mm aluminium sheet I had lying around but could have used thin plywood or MDF. I cut a 60mm hole with a hole saw for the front of the timer to go through.

Image

Then I set about wiring the timer up. I took live and negative feeds from the power socket above the ashtray in the centre console (purple/yellow is a permanent live and black is earth).

The FBH is triggered by earthing pin 3, so I ran a wire from there back inside the cabin and behind the centre console and under the armrest.

The switch is just a live and earth and and earth on the output and the trigger wire for the FBH, as its a simple circuit, even I could work it out :D

I covered the plate with some spare covering I had left over from when I recovered an old parcel shelf and popped it all in place.

Image

I took the opportunity to add an Aux Power Socket I picked up for £2.50 on Ebay.

Tested and all working fine. I dont think its too bad for less than £7.00. :D:D

Thanks Paul. I had looked for the Webasto timer but to be honest, it doesn't do anymore that this cheap jobby from China. I have a remote on order and I'll be fitting that in a week or so. That way I'll have all my options covered :-)

Well done Davey, looks a neat install.

I was wondering if it would look better if you extended the metal plate to cover the whole of the bottom of the cubby hole so its all the same colour ?

I'll look into that when I get chance, as I am fitting another aux power socket in the back of the car for my son to use on long journeys. :-)

If you want a remote, I used this: http://www.ebay.co.uk/itm/370820622781

Dead simple wiring.

Red = Live
Black and one of the yellows = Earth
Second yellow = Pin 3 on FBH.

Works up to about 40 yards away.

I don't understand how those sellers get away with selling those. They are 315MHz which isn't legal anywhere in Europe. They are meant for the USA and a few other markets. We should be using 433MHz or 868MHz.

Have you thought of arranging things so that the interior heater comes on at the same time? Nice warm engine and nice warm interior :)

Hi Paul,

I certainly have considered it. I have my eye on this:

Image

From here: http://www.lewisrendal.co.uk/mediac/450 ... 355564.jpg

Guy is selling on Ebay, at what seems one item at a time: http://www.ebay.co.uk/itm/181233194034? ... 1423.l2649

The plan long term is to get the ATC (Automatic Temperature Control) working on the GSM remote also.

Duncan, I had no idea the remote was illegal but these are all over Ebay, so its not just me with one and to be honest its used so little I am not sure it would cause much of an issue(??).

Dave :-)
