Controller 4 Screen Setup

The touchscreen may require additional setup before operating the fans. Please refer to the

steps below to properly configure your controller.

1. Power on the fans. The screen will illuminate as soon as power is supplied.

2. The screen will search for fans and take you to the home screen once the scan is

complete.

3. AVD 370 and Y series fans do not require further setup. If you only have these fans on the

network, set a speed and direction using the buttons on the home screen. Y series fans

will operate normally. AVD 370 fans will spin in reverse at a preset speed, automatically

determine the blade length and resume operation at the speed and direction command.

4. AVD3, 550, 780, and X series fans REQUIRE the blade size to be programmed in order to

function correctly. The blade size is set via the “Fan Diameter” screen. Once the size is

programmed into every AVD3, 550, 780, and X series fan on the network, the fans can be

operated normally.
