It is possible to use in a Multiplus the AUX I/O for Allow-to-charge and the Temp Sensor for Allow-to-discharge commands.
Do I have to connect both connection for this function, or is it possible to connect only the AUX I/O alone for Allow-to-Charge, leaving the Temp Sensor connection unused and unconnected?
My BMS has only one free relay output left and I need only the charge disconnect function for the Multiplus.

You need to get familiar with Assistants if you are going to use AUX I/O for ATC.
The temperature sensor for the Multi is not needed. Your BMS should take care of it and open ATC in case temperature is too low to charge.
Hi @Stefanie, thanks for this quick response.
I think this will fit. When going back to my boat on Saturday, I try to get familiar with the assistants. ;)
