2.2 Motor protection
The QT150 HT has an energy-saving maintenance-free EC Motor with high
efficiency. The motor is equipped with a thermal contact, wired in series, which
automatically switches on/off after cooling. If the motor is blocked there will be an
attempt to restart it every 3 seconds.
2.3 Start-up performance
To start the motor a certain rotor position is required. If it doesn’t detect it, it outputs
pulses to the rotor in order to reach this position. This may take a few seconds. After
switching off the fan, switch-on inhibit activates the fan for 15 sec. to protect the
motor from rapid on/off switching.
