Daikin Mini-Split Code CE
Warning
Presence sensor or floor sensor abnormality. The optional occupancy/floor-temperature sensor kit read as disconnected or shorted while the unit was running.
Manual wording: “CE Presence sensor or floor sensor abnormality”
Documented for: Indoor units fitted with the intelligent eye / floor sensor kit
Likely causes, most common first
- Disconnection of connector
- Breaking of wires
- Defective sensor(s)
- Defective sensor kit PCB
What you can safely check yourself
- Turn the system off at the breaker or disconnect switch and back on once
When to call a technician
The sensor kit plugs into connector X81 on the indoor PCB - reseating or replacing it is a technician's job. The unit will usually still heat and cool without the sensor.
A Daikin mini-split throwing this code repeatedly has a reason — clearing the code without fixing the cause just hides it.
