What it means
After the compressor stops, Pioneer controls wait about 3 minutes before the next compressor start. That protects the compressor and is not an error.
Urgency
Not an error
This is a normal status, reminder, or service-query indication, not an error by itself unless comfort is poor, water is present, or the indication will not clear.
Likely causes
Homeowner fix
Wait several minutes without repeatedly pressing buttons or cycling the breaker. Operation should resume when the protection timer finishes.
When to call a pro
Call for service if the unit never restarts after the delay, a breaker trips, or a separate code appears.
Repair vs replace
This is a status or maintenance indication, not a repair-or-replace decision.

Which systems show it

- Pioneer Diamante Essenza R-32 single-zone systems imported under the diamante-essenza product line; optional detector and fresh-air codes apply only to models/manuals that list those options.
