Daikin FKCAQ71AV16 unable to identify connector type

[dhruvbhutani]

Hi,
I'm unable to identify the connector type for wiring up. The PCB designations don't correspond to any of the recognised wiring connectors. Can I get some inputs here please?

The model number is Daikin FKCAQ71AV16
Thank you.

That is new!

My guess is X801, but worth carefully checking relative voltages all make sense, and being very careful in case they are live/mains levels.

Voltages relative to pin 5 (note pin 1 is bottom with triangle) should be, if it is S21 style:

Pin 1 may be 5V or 0V
Pin 2 and 3 should be around 5V
Pin 4 may be 12V ish, perhaps a few volts more, our may be 0V

If 5V on pin 1 and nothing on pin 4, then connect pin 1 on this to pin 4 on Faikin module.

As long as you don't connect more than 35V DC to pin 4 and no more than 5V to pins 2 and 3 on Faikin you should not fry it!

TAKE CARE OF POSSIBLE MAINS VOLTAGES!!!
