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
Confirm reboots match expected on/off cycles
Compare Reboot entries against known times the fan was switched on; matching entries are normal.
Investigate unexpected reboots
If reboots appear without the fan being intentionally cycled, suspect intermittent supply power to the board.
Check the power connection
Verify the controller's supply wiring is secure and the disconnect is not cycling.
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.
