FBH remote operation circuit - Page 4

bobthethird · 1st February 2009, 18:34

I am having exactly the same problems as yourself, the only difference is that I connected 12v to pin one which overrides the temperature sensor. Then use that 12v to power a 12v led from Maplin http://www.maplin.co.uk/module.aspx?moduleno=35738. I am currently working on a timer circuit for both fbh and ATc so that I can use the non-latch facility of the remote. I have the same remote as you.

I've just purchased a 12v remote switch with key fob from Maplin. I know I need to short pin 3 to make the FBH fire up as I've tested it by manually shorting pin 3 to gnd.

But: my remote switch can be set to momentary or latching switching. So a single press can turn on and another press turns off; or it turns on for the duration of the press and as soon as you stop pressing, turns off.

Which option do I need? Once its turned on, does it stay on until you disconnect pin 3? In which case latching. Or is it timed? If I use latching, will turning the engine on for a journey, then stopping override it and switch it off?

If latching, I'll have to rig up some sort of indicator too so I don't accidentally leave it on and flatten my battery...

tnx for any advice or suggestions (other than spending loads on a proper Webasto one!)

A little pricey for a switch, but cool. You can't get much better than sitting in your office at work and phoning your car to turn on the heater!!
