Mitsubishi Electric air conditioner remote symbols
13 buttons and icons that Mitsubishi Electric itself documents, each in our own drawing, with Mitsubishi Electric’s name for it in quotes and what Mitsubishi Electric’s document says it does. Tap a drawing for the symbol’s own page: how other makes use it and every source.
Makes differ, check your unit’s manual: the same drawing can mean different things on different brands, and only your model’s manual says exactly what a button does and which modes it works in.
Read this first
The source is Mitsubishi Electric’s service manual for the MSZ-LN wall-mounted indoor units (OBH766, revised edition B), from its UK library. It is written for installers, so it is exact about temperatures and timings. Modes are chosen with the OPERATION SELECT button; up-and-down swing is on VANE CONTROL and left-and-right swing on WIDE VANE.

Not listed for Mitsubishi Electric
The Mitsubishi Electric document checked here does not explain these symbols from this site, so they are left off this page: Fan speed, Sleep mode, Quiet / Silence, I Feel / Follow Me, Clean-filter reminder, Defrost indicator, Self-clean, 8 °C / 10 °C frost-guard heating. That does not mean no Mitsubishi Electric unit has them, only that the Mitsubishi Electric source cited here does not describe them. If your remote shows one, find it by its shape.
