Multiplus-II GX Aux Relay Temperature control

Hello there , I am trying to figure out how to manage room temperature based on values from Pylontech BMS or Multiplus external temp sensor. I' like to control AUX Relay on multiplus itself to regulate room temp in which the system is placed in.

Couldn't find any answers from my retailer so I hope someone here has experience on this topic.

Thank you for feedback

Best regards. Sam.

Node red on the big OS is a possibility.

I have not tried it.

At the end of the day an air con unit has its own temperature control so usually is the go to for room control.

You can use the K1 relay to drive a fan based on whether the fan in the multi is on.

You will need 2 conditions one for on one for off.
