Protection mode
electronics
overheating
The unit is currently in protection mode. The power transmitted to the motor is deliberately
reduced to decrease electronics temperature. The unit will exit this mode by itself once
conditions are back to normal. It is normal to observe reduction in airows during this period.
This condition should appear only when the unit is set in high speed and located in a warmer
environment, for example over 30°C (86°F).
8. INSTALLER’S TROUBLESHOOTING (cont’d)
Make sure that no piece of mineral wool will enter in the unit during installation. Otherwise, this could reduce
airow and generate vibrations and noise in the unit.
