  • Independent Control of 3 Banks of Fans
  • On/Off & Variable Speed Based on Temperature
  • Variable Speed Fan Control Based on Temperature
  • 3 Alarm Modes to Protect Systems from Overheating
  • Sensors can be Extended for Remote Equipment Applications
  • Compact Size for Easy Placement

Fan Modes
Mode 1: On at 70F This mode will not be used often for AV cooling, only in cold rooms
Mode 2: 80F Use for room/closet cooling
Mode 3: 90F Used primarily for cabinet spot cooling and venting (default mode)
Mode 4: 100F Cabinet spot cooling , venting, and secondary cooling systems (backup systems)
Mode 5: 110F Primarily for secondary/backup cooling

Alarm Modes

Installation Overview
The controller is installed inline utilizing a 12V DC power supply plugged into the controller which in turn connects to the fans.  When connecting, ensure polarity is correct by aligning on the cable ends, Tip to + and that the connection is secure.

Find a centralized place for the controller and ensure the fan and sensor wires can reach the desired areas to be monitored and fan locations.  Place the sensors in the areas where hot air will accumulate but not directly on equipment as the fans may ramp up too fast and/or never turn off.

Preplanning the programming will save time and potential frustration.  Simply take note of desired settings for each fan bank and the alarm settings.

The unit should be accessible and can be mounted to a surface either with the supplied screws or other fastening methods (velcro works well but is not included).  Connect the fans and power supply to the controller (ensure proper polarity).  Once powered the LED should illuminate green.  Each of the fan leads and sensors should be for a specific zone/component within the system, ensure the sensor corresponds to the fan!

Sensor Location & Installation:  For spot cooling, mount the sensor in the vicinity of the component are cooling. For cabinet cooling, mount the sensor high in the cabinet and close to the fan unit (in or close to the airflow path).

Programming is done using the button on the side of the controller. It is best to know your plan before attempting to program it. This simply means know ahead of time the desired modes/settings: Fan 1 Mode, Fan2 Mode, Fan3 Mode, Alarm Mode.  
To make programming easier, pay attention to the LED colors:  Fan 1 = Green, Fan 2 = Red, Fan 3 = Orange

Fan Mode Programming.  To enter programming mode, simply press the button and the green LED will flash and beep corresponding to the current mode (quick beeps). To change the mode, press the button corresponding to the desired mode (1 press = Mode 1...). After 1 second, the unit will beep to confirm the mode.  If mode is not correct, simply re-press the button for the desired mode.  Once the mode is correct, press the button for 1 second to move to Fan 2 (LED = Red), . Once program Fan 2, press the button again for 1 second to move to Fan 3 (orange LED)  Unit will time out after 5 seconds or press the button for 1 second to exit programming.

Alarm Programming.  Press and hold the button for 3 seconds and the green light will flash quickly and beep corresponding to the currently set mode.  Press the button corresponding to the desired mode.  Unit will beep corresponding to the mode and exit the same as with the fan programming.  The unit will time out after 5 seconds or press the button for 1 second to exit.

Fan Mode Program Review.  Quickly press the button 3 times and the unit will review the selected modes.  Once entering review mode, the unit will display green for Fan 1 and beep once indicating Fan 1, then beep the current mode, once done, will automatically move to Fan 2 and LED will change to red and there will be 2 quick beeps, Fan 3, orange LED...  The unit will time out after 5 seconds or press the button for 1 second to exit.
