Is Thermostats compatible with CN1 connecter from Fuji

[Alowa]

Hello,

I've a Fuji AC with three wires CN1, it seams to be not compatible with Thermostats.

Is it compatible or is there some sort of converter or dongle that could be used. here are pics

@Alowa 

No, your current system is incompatible with any Nest thermostats, and I have no idea if Fuji offers an adapter.

Hello folks,

I wanted to stop by and see how I could help.

Thanks for lending a hand here, @Patrick_Caezza.

@Alowa, in addition to what was mentioned above, your system is proprietary if you discover wires in your thermostat's connector with unusual designations, such as 1, 2, 3, or A, B, or C. Google Nest thermostats are incompatible with proprietary systems. However, a skilled installation can rewire certain proprietary systems to make them interoperable.

Let us know if you have more questions.

Regards,
Mark

Hi @Patrick_Caezza and @Markjosephp ,

Thank you for your feedback, I'll get a professional you check if different wiring is present in the main board of the outdoor unit.

Hi Jenelyn,

I'm having a professional to check the AC main board for different wiring, but he is scheduled on 28th this month.

so if you could leave the threat until then, I'll be updating and if applicable sharing photos.

Best R,

Dear Zoe,

Unfortunately, with the expertise around my place no one seems to know how to rewire the Fuji proprietary systems. I'll share the wiring label and the main board photos.

Thank you @Patrick_Caezza @Markjosephp @Jenelyn_O @zoeuvre  and its time to close this threat.
