Fan Controller Connections

Thermal Probe

Fan Controller:

User sets the controller's on and off temps to start and stop the system. Set a Global temp that will control all 4 fans together and/or set individual temps for each fan.
Each of the 4 fan power connectors are numbered 1 thru 4 corresponding to the front panel LED indicators. When the LED's are on that fan will be on. When the LED's are off those fans will be off.
Global setting: Front panel LED's for fans 1-4 are all on.
Individual setting: Front panel LED on for the selected or operating fans.

Typical start temp is about 80-85F. Off temp at or slightly above room temp. These settings can be adjusted for optimal performance. The controller has a temp sensor that should be located on or near the heat source, or can be located at the top of the cabinet for an ambient reading. This temp is displayed on the controller during operation for easy monitoring. Or, the display can be shut off during operation. (See Operating instructions)

Programming Temperature profiles:

Set the Global range higher than individual fan settings. If the highest individual temp is for example 90F set the Global temp to 92F or higher. If the Global temp is set to start at 85F then any fans set to start at 90F they will start when the Global start point of 85F is reached. Likewise if using the Global setting, make sure all individual settings are set outside of the Global range. The same rule applies for the OFF settings.

Care and Maintenance

To maintain optimal performance, keep the fans clean. Canned air works well. If the fans are used outdoors or in a dusty environment is recommended to clean the fan blades as needed to keep clean.

Blade Removal

For cleaning and maintenance, the blade prop can be removed.
Grasp the blade prop and pull straight out of the fan body. Inspect the shaft and lubricate if needed. Any oil will work; light grease works best. Clean blade as needed with a dry cloth. Soap and water can be used if needed, but should be thoroughly rinsed and dried before use. Reinstall the blade; when properly installed the blade will snap into place.


The fan will not start:

1. Is the controller display on? If Yes, skip to #3.
2. Check the power connections. The power supply has a green led indicator, it should be on. If it is not check the power source. If not lit or flashing, it would indicate power supply failure or no power source power.
3. Check that the fan plugs are all plugged in on the back of the controller.
4. Check the fan blades to make sure they are fully seated in the housing. Press on the center of the blade and push in. If it is not seated you can hear it snap into place.
5. Turn the fan blade by hand to see if they are stuck. They should be free moving. If this starts the fan it is likely the fans need maintenance.

The fan is making noise:

1. Check for anything that could be rubbing against the fan blade.
2. Make sure the fan blades are clean. Dirty fan blades can cause a rattling noise.
3. Check the blade prop shaft for lubrication. (See step #3 above)
