United Kingdom 2006 Discovery 3 TDV6 HSE Manual Buckingham BlueDiscovery 3

Hi everyone,
since a few weeks now I am the proud owner of a 2006 Disco 3 Very Happy. I have sourced a Thermo Call TC3 unit from Germany that finally arrived today after some delay due to extreme weather Big Cry.



I have spent some time reading on this forum and elsewhere about fitting a remote or timer to control my FBH and have the following question:

Where on the TC3 do I connect the cable that goes to Pin 2 on the FBH control plug?

Hope that you can help me so that I can fit this during the next weekend...

Hi,

do I understand right for the TC3 :

Pin 1 (10-30v + in) to Battery plus
Pin 2 (GND) to Battery minus
Pin 6 (W-Bus) to Pin 2 of the Webasto unit

The picture https://www.disco3.co.uk/gallery/albums/us...e~149.jpeg shows it nicely . unfortunately I can not see where the green connector is going to , blue goes to 6 , red goes to 1 , but the green one ? I assume its 2 , correct?

That´s all ? Is this correct ?

THX Smile

Just for those who still struggle as I (noob) did :

TC3 ("D" series)


Pin 1 to battery plus (red cable)
Pin 5 to battery minus (brown cable)
Pin 6 to Bus input ( input 2 in the 8 wire socket in the heater) - check the wiki how to connect the plug and the socket

App:

-no external temp sensor used - app on "internal sensor"

-make sure to only use the last 7 digits of your phone number for installing - I had an error because of using the complete one

- it works - just sends me the message "unknown error" to the phone - but works . will see how to get this sorted . Tomorrow i will built it in properly incl. the red light button which I will bring to some place in the inside,,,
