Normal status Kinghome KM HT1DIKinghome KM HF1DI

What the display is showing

During defrosting in heating mode the heating lamp pattern is off for about 3 s then blinks once, with the lamp on for 10 s and off for 0.5 s. The compressor keeps running while the indoor fan stops. The manual calls this the normal state. The on-screen code for this row did not survive the text export, so only the lamp pattern is given.
