Hello Gary, So whats going on and what can i help you with?
Customer: replied 7 months ago.
Picked up a mini-split used, no remote. attempting to use a universal remote , obvious communication problems. Is their a code to enter into remote? any schematics available? etc outside unit 38qrf018-301 inside 40kmq01824-301 carrier
Expert:  Sean replied 7 months ago.
Ill see if I have any info on this particular model
Expert:  Sean replied 7 months ago.
I don't have programming info on this but I did find some universal codes that I had in my folder for mini splits. For Carrier 690-699 890-899
Expert:  Sean replied 7 months ago.
Do those codes help you.
Customer: replied 7 months ago.
If this doesn't work can we wire up a standard 24v t-stat?
Expert:  Sean replied 7 months ago.
Trying to find a wiring diagram now :)
Expert:  Sean replied 7 months ago.
Doesn't look like a standard t-stat will work, There set up for a wireless thermostat like you have
Customer: replied 7 months ago.
If I could bypass the inside board and get the fan to un on a 24v relay, I think I can get it to run on a normal tstat
Expert:  Sean replied 7 months ago.
That i don't no. I looked at a carrier wiring diagram it shows nothing about a thermostat for this model, I can opt out and see if someone else can help you?
Customer: replied 7 months ago.
do you have a wiring schematic for the inside unit?
Customer: replied 7 months ago.
opt out?
Expert:  Sean replied 7 months ago.
Not for this exact one, No I do not and can't find one. I found a generic carrier one in my truck,Opt out means we can let someone else try and answer your question.

Here is the manualhttps://catalog.dcne.com/catalog/Data/00165.ECC/00171.PDFschematic wont give you the info your looking for, Does your universal remote specify it supports Carrier models?
