So compressor terminals. R goes to the other. S goes to the HERM terminal on a capacitor with the other side of that capacitor (C) going to the same leg that feeds R. C what I’m saying? It is a red wire and comes from the transformer usually located in the air handler for split systems, but you may find the transformer in the condensing unit. Step 4 Examine the top of the capacitor. capacitor which is usually marked with a “C” or “=”. For instance if C to S reads .02 ohms and C to Run = .04 ohms, then C to R should be around .06 ohms. Home Diagrams C.S.R Compressor Wiring Diagram Single Phase With voltage Type Relay. Vapor-compression uses a circulating liquid refrigerant as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere. im not so sure though. Your compressor may show a different measurement of Ohms, but as long as you get resistance, it is a good sign. Berikut ini kami jelaskan secara sederhana cara menentukan C.S.R compressor. Google Arts & Culture features content from over 2000 leading museums and archives who have partnered with the Google Cultural Institute to bring the world's treasures online.
