Power on the Hub:

Switch on power to the hub, the Power indicator on the hub will be on, and other three indicators will stay off. Press the Test button to change fan speed, the fan will run in the following cycles:

1 speed fan:

2 speed fan:

3 speed fan: high speed -> medium speed -> low speed -> off -> high speed -> medium speed -> low speed -> off. on -> off -> on -> off, high speed -> low speed -> off -> high speed -> low speed -> off, And, the Test indicator will blink as follows:

Low speed on: the speed LED will blink once every 2 seconds, Medium speed on: the speed LED will blink twice every 2 seconds, and High speed on: the speed LED will blink three times every 2 seconds. Notes:

If the corresponding DIP switch of the fan is configured incorrectly, all the indicators on the hub will keep blinking when the hub is powered on. Please switch off power and re-configure the DIP switch correctly. Then try again. Rev 2.0 Page 2 of 2
