So what ones have you mixed and matched? Your saying that you can match a Fujitsu to a mits or samsung or visa versa as long as it's 2 ton? Again never tried so not saying your wrong.

Do you have a wiring diagram.

Same pressures, same pipe sizes, same refrigerant then yes, why not? Might have to add a relay/contactor if the evap fan is a different voltage or jump out a lp/hp switch if there isn't one. Why would u think it wouldn't work?

Different boards, different signals re communication to and from units, different faults and fan speeds re thermistors in coils, I can think of a bunch of stuff but again never seen it done, the unit shown does look pretty basic though, just seems like a whole bunch of different. The units communicate through DC voltage curves not just a on and off contactor in the head, jump out a pressure switch, why would you have to do that? There are no pressure switches in a head that I've ever seen. Anyways to OP be very careful lol.

There should be a diagram on the back of the panel for the wire connections, well most have one lol.

Basic 7 wire, 2 speed fan motor, rt1(room temp), rt2(
No curves in DC voltage, temps use a 4-20ma or 0-10 vdc signal. I didn't say all splits either. The "signals" are just on and off , only thing being monitored is temps, pressure switches,etc(alarms) and input voltages. Nothing else.

Ok, like I said, never seen it done is all, curious why a pressure switch would need to do removed, shouldn't effect anything as its a safety (in series). And yes temps are read through thermistors, which changes with temp. So not sure how it's an on or off thing. Anyways all I'm saying to OP is be careful, as you said not all are compatable
. I'm thinking out of the 4-5 main brands none are compatable although I agree that one is not a main brand lol.

It's hard to get what your trying to say without writing a essay....Never mind trying to explain tech shit lol

so some guy said its not a minisplit(ductless) but a conventional horizontal discharge ac unit. idk really. sond familliar to anyone?

its a rotary compressor. but im interested in the part u were talkin about...

Oh ok then lol. But I would understand as I've had my refrigeration licence for 35 years

. I don't see a board there so probably is just a condenser and its not an inverter compressor. So yup everyone is right but for all the wrong reasons lol. Probably could just change the contactor to 24 volts and use a regular evap coil and air handler

Oh and don't take out the pressure switch circuit, that's a bad thing lol.

What's up how can I help you. I am an air conditioning contractor and have been doing minisplit AC systems most of my life. Don't take our any thing

Chances are that the unit is fine. Get the numbers of the compresser. I know that I have the other part of the unit. The evaporator coil

Oh and it is a minis minisplit system ,because it says it on the tag .WALL MOUNT TYPE. And it is an inverter compresser because it also says heat/ cooling .
