Hi Martin

I tested and measure wbus data today. TT-V repsonse every command w/o any problem. And also manual push button is perfectly working. If you connect external temp sensor you can get the alarm from TC-3 Smile I'm realy happy Thumbs Up

If you can monitor the WBUS can you see what the address byte of the WBUS command is please? It is the first byte of the command Smile 06 D3 SE / 15 LR D90 XS SW / 88 LR 90 Td5 / 68 BMW 2000 ti

When you send start, you should get a message of 4 bytes in length: address, length, command, checksum. The heater will then reply with a message of 4 bytes.

There will be a lot of communication to determine the status of the heater and get information, but the start command will be something like:

0x?? 0x03 0x21 0x1E 0x??

The first ?? contains the TC3 address. The last ?? is the checksum. 06 D3 SE / 15 LR D90 XS SW / 88 LR 90 Td5 / 68 BMW 2000 ti

Actually, any first byte of any of the commands would tell us what the address is Embarassed 06 D3 SE / 15 LR D90 XS SW / 88 LR 90 Td5 / 68 BMW 2000 ti

I wonder what the differences are those TC3 for? I have found the following versions of 7100350B, 7100350C, 7100353A; B and C. The question of which version works LR in? or does it matter? Embarassed

Maybe the firmware version or gsm chip is different. I sent mail to webasto but I didn't get any mail from them.

Hi ,
Thanks for the topic. I followed the instructions and it's working. Only one question : after start it's not responding to Stop command, why? It needs to reach the specified temperature or must finalize the countdown?
Thanks again! [/i] EGR blanked.

Temp sensor ( external ) ?

Hi,
One question : how to conect the external temperature sensor, the one from webasto, for the TC3 ?
I'm a little confused, to much wires. Sad

Thanks EGR blanked.

It is very easy Smile because temperature sensor has only 1 socket,you can see the female socket than connect to there. You must select external sensor from the webasto app

You must put the sensor front side behind the grill, othervise app show wrong temperature !
