Default How to operate your FBH and ATC by text.

This "How to" applies only to the FBH like this.



You will need to order a GSM unit.

This one by lewisrendel. This is his Ebay site.

When you place your order, it would be worth mentioning the requirements of the GSM unit i.e. what you want it to do. That way he will program it so the relays are timed - e.g. relay 1 comes on straight away, relay 2 comes on after 5 mines and then both turn off together after 20 mins. Otherwise I think you'll have to program the relay yourself using his instructions or text the relay to turn it back off.

GSM relay:

+V: wire to 12v feed from fuse box (5amp fuse)
Negative: wire to suitable earth.

Relay 1 for FBH:
NO: wire to pin 3 on FBH.
C (or NC if labelled incorrectly on GSM): wire to earth

Relay 2 for Heater Controls:
NO: wire to pin 13 of DPDT relay (based on the DPDT relay in the pic in post 1)
C (or NC if labelled incorrectly on GSM): wire to +12 from fusebox (5 amp fuse)



http://www.ebay.co.uk/itm/401030979071



You will also need a Double Pole Double Throw relay.

Here is one.

http://www.ebay.co.uk/itm/191590027847


You will need to connect a black wire to pin 3 of your FBH.



WARNING: when wiring to pin 3 of the 6 pin plug for the FBH, make sure you remove the little blue rubber blank from the pin. You will need to use either tweezers or a needl and dont push down on the rubber blank otherwise it pushes down the plug and becomes a real pain to remove.

You will need red wire for a permanent live 12v to operate your GSM and your ACT panel.

Use one of these, readily available from Ebay.

For those who have earlier models they will have the older style larger fuses so would need the larger fuse taps, just in case they order the wrong ones.

Rick-sta used 2 fuse taps, 1 to power the 2 12v's required for the DPDT relay, and 1 for the 2 12v's required for the GSM unit, this may be advisable.







You will need a earth connection.



These are the wires to cut and connect to your DPDT relay



This how to wire the lewisrendel GSM unit.



Before wiring relay 1 and 2 check that the connection markings are correct because Rick-sta and Tony (awvc1) found that the C and NC terminals are labelled the wrong way around. We've both had to wire ours to the NO and NC terminals to get it to work. So it's advisable to check.

This is the diagram to wire the DPDT relay



And this is how to wire the double pole double throw relay.

My 12 pin Double Pole Double Throw Relay (from the picture in post 1 above):
Pin 1: White/Orange wire for AC (Car side)
Pin 2: Green/White wire for AC (Car Side)
Pin 5: 12v feed from fuse box (5amp fuse)
Pin 6: 12v feed from fuse box (5amp fuse)
Pin 9: White/Orange wire for AC (AC Controls Side)
Pin 10: Green/White wire for AC (AC Controls Side)
Pin 13: 12v feed from relay 2 GSM unit terminal NO
Pin 14: Wire to Earth



Locate your GSM unit in the center cubby.



Wiring:
I used 14AMP rated 0.75 thin wall cable I had left over from my cruise control retrofit, which can be purchased from ebay. See here http://www.ebay.co.uk/itm/50M-Roll-1...a8NlkEOCyrOqZw


My DPDT relay is placed next to the heater controls in the centre consol. When you take the heater controls out, you'll notice there is a lot of space to the left or right of where the unit goes, so I secured mine on one side.

You will need female spade connectors for the DPDT relay like these: http://www.ebay.co.uk/itm/FEMALE-SPA...3:m:mKuqdvB5Uo 6kvlkxRQEDxDgI can't remember what side I used now, I simply popped down to my local private DIY store and picked the size that would fit the spades on my DPDT relay.

I placed my GSM unit in the centre cubby hole simply for easy access just in case I needed to get to it, for example to register another mobile number (the GSM will only accept texts and calls from registered numbers, this prevents those PPI nusance callers from activating your FBH). To run the cables to the GSM unit, you will need to pop up the gear surround and handbrake gaiter, and you will need to drill a hole in the bottom of your cubby hole (make sure you remove the cubby hole from the car and drill it outside). It is held in place with two torx head screws, simply remove screws and pop out.

When running the cables from the heater controls to the GSM unit in the cubby hole, make sure you keep the cables clear of the gear stick and the hand brake (wouldn't want it to get caught).

I'd also advise fitting a quick release plug like the one in the link below for the wires running to the GSM relay, which was advised to me by Dave (Duotone), to prevent shorting the relay whilst connecting or removing wires from the terminal. I did this by accident first and blew two of my fuses You'll need a 6 pin for the GSM unit.
http://www.ebay.co.uk/itm/Tyco-AMP-E...Wsrc0SFlCqeIWw


When all connected you will be able to operate the FBH by sending the text RT this will turn on your FBH via relay 1, after 5 minutes relay 2 will operate sending 12v to your DPDT relay. The DPDT relay will then switch on your ATC unit for a further 15 minutes.

After a total of 20 minutes the FBH and ATC will shut down.

ATC running without ignition key.



To register your phone to the GSM unit i.e. you have to power the GSM unit, flick the on switch, call the relay (it will ring a couple times and cut off) and then flick the switch off. This registers your number with the relay.

Retrofitting Fuel Burning Heater:
I also had to retrofit the FBH itself, so for those who don't currently have a fuel burning heater fitted to their diesel and would like to fit one, here is a link to a very useful how to on servicing and fitting a fuel burning heater.
http://www.the75andztclub.co.uk/foru...d.php?t=100297


Thanks to DaveyC for the original idea and to Rick-sta, awvc1, David Lawrence and anyone who has helped.

I have brought all the info and pictures together to make this "How to"

Please comment/ correct this "How to" and after it is checked I will ask a mod to add it to the "How to " forum.

Well done Dave Covered everything nicely there

Just to nicely summarise the guidance above, here's the list of wiring I wrote up for myself when doing the GSM mod on mine:

GSM relay:

+V: wire to 12v feed from fuse box (5amp fuse)
Negative: wire to suitable earth.

Relay 1 for FBH:
NO: wire to pin 3 on FBH.
C (or NC if labelled incorrectly on GSM): wire to earth

Relay 2 for Heater Controls:
NO: wire to pin 13 of DPDT relay (based on the DPDT relay in the pic in post 1)
C (or NC if labelled incorrectly on GSM): wire to +12 from fusebox (5 amp fuse)


My 12 pin Double Pole Double Throw Relay (from the picture in post 1 above):
Pin 1: White/Orange wire for AC (Car side)
Pin 2: Green/White wire for AC (Car Side)
Pin 5: 12v feed from fuse box (5amp fuse)
Pin 6: 12v feed from fuse box (5amp fuse)
Pin 9: White/Orange wire for AC (AC Controls Side)
Pin 10: Green/White wire for AC (AC Controls Side)
Pin 13: 12v feed from relay 2 GSM unit terminal NO
Pin 14: Wire to Earth

12v Power Feed:
I used two fuse taps (in the pic in post 1) to power my two relays. The way they work is you remove any existing fuse from your interior fuse box, and put the fuse tap in it's place. The fuse tap has two fuse slots, 1 for the existing fuse you removed, and the second for the feed you wish to create. See picture below:


The first fuse tap i split into two feeds and wired both to the GSM relay (1 to power the relay and the other to terminal C of Relay 2.
The second fuse tap I again split into two feeds and connected it to pins 5 and 6 of the DBDT relay. You will need to use 5 amp fuses for your feeds (you will need two 5 amp fuses).

Wiring from FBH to GSM relay:

To run an wire from Pin 3 of the FBH to the GSM unit inside the car, you will need to run your wiring a long the back of the engine bay, across to the driver's side and pass it through the rubber grommit in the driver side plenum which you can see in the pics below. Once passed through here, you will be able to retrieve the wiring from the driver's side footwell after dropping down the panel above the foot pedals which is held on with 2 screws. The wire can then be passed through to the centre cubby hole.





WARNING: when wiring to pin 3 of the 6 pin plug for the FBH, make sure you remove the little blue rubber blank from the pin. You will need to use either tweezers or a needl and dont push down on the rubber blank otherwise it pushes down the plug and becomes a real pain to remove. Trust me, I found out the hard way

Hope these two posts covers everything you need to know to do this mod

Thanks again Dave for all your help

Great "How to" - definitely should be moved to the How To section.

This is something I would like to do and armed with this I will be able to get someone to do it for me !!!

Seriously - I would not want to do this myself but an auto electrician friend of my son's will have no trouble armed with this.

Great stuff!

I messaged lewisrendal on ebay earlier HERE and he is aware of the fitment for our cars and the Webasto FBH system.

Incidentally, he has quoted his "Buy it Now" price as £35 plus £0.90 for signed shipping/Delivery for the GSM Controller.

At least half the price of a Webasto timer with remote!

Lewisrendal is a top bloke for customer service as well. He helped me out when i stupidly put my sim card in the wrong way round, and provided advice when needed until i had finished the install. Buy from him with confidence.

Lets face it, he has a specific setting in his unit just for us, who could ask for more than that?

I am thinking of Trying to fit one of these after reading the know how,and would like to say thanks to all of those that have put this all together.
I will be getting one of lewisrendal to make it easyer. I have done a diagram of sorts useing the photos could some kind person check to see if I am right with where I have got each wire going and put me right if Im wrong.Not used to wiring.
