Hello
Could anyone help me to solve my issue. I mounted Cylinder unit (EHST20C-VM2DR1) and outdoor unit (PUHZ-FRP71VHA2).
The system doesn't starting up at all. On outdoor unit I get error GREEN LED - 2 blinking and RED LED 1 blinking, on Indoor unit I get error EC . 
I attached two videos with my setup.
Here I used separate shielded wire for communication, error still there.
My question is : Does external unit (PUHZ-FRP71VHA2) capable to work just with cylinder unit and without ATA (indoor unit). If it is possible, could  you be so kind and give me the correct DIP switches combination to make it to work as it should be. 
Sincerely 
  Alex.

Alex,

I doubt there is anyone here with the sort of detailed knowledge.  I suggest you try one of the Facebook Mitsubishi groups as they have installers who may know.  Try this one:
