Hi guys. New here and have a quick question. My general area of knowledge is hydronics but I have a heat pump question. Replaced a York condenser with a Trane XLi unit last week. 3 ton unit. York air handler inside with 11.3 KW coils. My question is about low voltage wiring between condenser and air handler. R,W,G,Y,O,X,B are all obvious connections at the air handler. However I have 3 other terminals labelled 66, 60 and 53. For no aux heat the air handler has a jumper between these three terms and 66 becomes W. I'm at a complete loss with this as this is NOT my area. Any help or manuals you could point me to would be most appreciated.

Thanks.
K

No, I only have a few York fancoil manuals and I checked them all.

It should be noted that you risk voiding compressor warranty with a mismatched system like yours. This is doubley so with a heat pump.
