I want to run the Carrier Indoor unit 40MVC012 without outdoor unit. I tried with 35VDC & 12VDC as per PCB information, I can able to ON the unit with 12VDC, and its not working when i tried to run the indoor fan with 35VDC power supply.

As per carrier supplier the unit should run with outdoor unit, but we are connecting this indoor unit with our DX system, that's why we didn't buy outdoor unit.
If anyone solved this kind of issue, please advise me how to run the unit.

please find the attached pictures for your reference.
