What this means
The unit is in forced cooling/test operation, not a fault. It ignores the room-temperature sensor and automatically cancels after 60 minutes unless stopped earlier.
What you can check yourself
- Cancel the test with the remote START/STOP button or hold the forced-cooling button for 3 seconds.
