The Bonaire navigator thermostat control not only operates your heating system but also monitors and controls all its functions. If the system encounters any issues during operation, the Bonaire controller will display an error code symbol on its screen.
Experiencing issues with your system? Before calling for service, try a simple reboot first. Unplug the unit from the power plug or turn off the main power switch from your switchboard for at least 5 – 10 minutes. This can often resolve minor glitches.
If the problem persists and the error code doesnt go away, Don’t hesitate to call us on 0411 792 669 – 24/7 Emergency On Call
