What does Floaire Reboot mean?
Reboot is logged in the MSC Fault History any time the fan goes from OFF to ON. It is recorded as a fault for tracking purposes only and displays solely within Fault History; it is also tallied under Fault Totals. A Reboot entry by itself indicates a normal power or run-state cycle of the controller rather than an equipment defect.
Symptoms
- Reboot entries appear in the MSC Fault History
- Reboot count shown in Fault Totals
- Entries coincide with the fan being switched on
Common causes
- Fan transitioned from OFF to ON, which the board logs as a reboot
- Repeated power cycling of the controller
- Intermittent supply power causing the board to restart
Diagnostic steps
- 01
Confirm reboots match expected on/off cycles
Compare Reboot entries against known times the fan was switched on; matching entries are normal.
- 02
Investigate unexpected reboots
If reboots appear without the fan being intentionally cycled, suspect intermittent supply power to the board.
- 03
Check the power connection
Verify the controller's supply wiring is secure and the disconnect is not cycling.
- 04
Clear history and monitor
Use Clear Faults to reset the log, then watch whether new reboots appear without an intentional power cycle.

When to call a professional
A single Reboot entry tied to switching the fan on needs no service. Call a qualified electrician or technician only if reboots recur without the fan being intentionally cycled, which can point to intermittent supply power or a wiring fault. Tracing unstable line power to the controller involves live electrical testing inside the enclosure and should be left to a professional with proper tools and training.
