Self-check beeps (wireless remote) Wireless remote self-check feedback

Normal status Mr. Slim PEAD-RP JA(L) ducted indoor unit

What the display is showing

During self-check with the wireless remote, the indoor unit gives two beeps to confirm the start signal was received. If no further beeps come and the OPERATION INDICATOR lamp does not light, no errors are stored. Three beeps in a row (0.4 s each) after the first two mean the refrigerant address entered is wrong. Real errors show as a beep/lamp flash count.
