The controoler is Danfoss type MCX20B and also what is the meaning of error 032 showing in the display panel with rotating circle in the middle of display panel. hope to hear some answer, thanks a lot
Have you tried Danfoss?

You will have to contact Tecnair for the password but I doubt they would give it to you or that it would be useful as the controller is specifically programmed for close control.
I would surmise with the "rotating circle in middle of display" you have a comms fault
Contact Tecnair for the fault code it will tell you if it is BMS related or analogue input etc.
Thanks Guys appreciated
Yes, it's a canbus communication error between board and display. Check the flat cable plugs.
