Noob-Questions before i start getting deeper into this great project

[guevara777]

First things first: Thank you for this great project. I want to try using it with my Junkers ZBS 16 83 S2 MA.

I have to questions before start digging deeper into it. Maybe someone here can help me. Thank you.

1.) I do have the "1-2-4-6-A-F"-Interface on my device, but no TA270 oder TA300 connected to it. Do i need a connected room thermostat or is this optional?

2.) The wiring between the Interface and the niren-board has to be this way?

"1-2-4-6-A-F"-Interface <--------> Niren MCP2515 + TJA1050
"2" (CAN HIGH)          <--------> "H" (high)
"6" (CAN LOW)           <--------> "L" (high)

or is it "4" (CAN LOW). This picture is confusing to me:

It seems i only have a TA 211 e-Module with 1-2-4-A-F, not a BM1 oder BM2-Module.
Is it possible to add a BM1 oder BM2-Module to this setup?

Hi there :)

It appears as if the module you are currently using does not have a CAN interface built in. For this you would need to swap that manual thing out and replace it with a BM1 bus module first. Then you may use the CAN interface as described ;)
