Fujitsu Heat Pump: Change the wireless remote custom code (A/B/C/D)
Change the wireless remote custom code (A/B/C/D) on a Fujitsu heat pump: The indoor unit only answers to a remote with the same custom code; the default is A and it returns to A when the batteries are replaced.
Applies to: Fujitsu ductless heat pumps: Fujitsu wall-mounted 7-15 (NA ASU/AOU type); Fujitsu ductless heat pumps: Fujitsu slim duct ARU 7-18 (LL type)
How to fix change the wireless remote custom code (a/b/c/d): step by step
- Press START/STOP until only the clock shows on the remote.
- Hold MODE for 5 seconds or more to show the current code.
- Press SET TEMP up or down to cycle A, B, C, D.
- Press MODE again to return to the clock and store it.
- If no key is pressed within 30 seconds the remote goes back to the clock without a change.
