Bypass open/close

[cheick66]

Hi,
I have a Vallox 270MV connected via LAN/ModBus .
Is it possible to open/close the bypass? I found a lot of registers but can't figure out which to change.

1_BYPASS_LOCKED_CYC | 0 | 2023-03-16 16:45:30
1_BYPASS_LOCKED_EXT | undefined | 2023-03-16 16:45:30
1_BYPASS_MODE | undefined | 2023-03-16 16:45:30
1_CELL_STATE_BYPASS | 0 | 2023-03-16 16:45:30
1_DIG_IN_BYPASS | 0 | 2023-03-16 16:45:30
1_IN_BYPASS | 0 | 2023-03-16 16:45:30
1_IO_BYPASS | 0 | 2023-03-16 16:45:30
1_PARTIAL_BYPASS | 0 | 2023-03-16 16:45:30
1_RELAY_BYPASS_STATE | 0

Can you give me some help?

Best regards
Christian

I personally only control bypass lock. It prevents bypass opening. Not sure if other registers can be used or not. You can experiment. By setting temperature you can force it to open.
