Troubleshooting 

Problem 

Solution 

Fan does not turn on 

-

 

Verify that the fan has a constant 12v to it. 

-

 

Verify that the controller has power and that the LEDs are on. 

-

 

Verify the Speed and Trigger wiring between the fan and the 
controller. 

-

 

Test the fan by disconnecting the controller, and jumping 12v to 
the Trigger Output signal.  After a moment the fan should turn on 
and go to full speed. 

Fan does not turn on with 
air conditioning input 

-

 

Verify that the AC system is either grounding or providing 12v to 
the air conditioning input. 

-

 

Wait 5 seconds for the fan to turn on. 

After a short delay, the fan 
turns on, and won’t turn off 

-

 

Check the Remote Status LED to see if it blinks 3 times after being 
steady for 5 seconds.  This indicates that the air conditioning 
input is active.  

-

 

Disconnect the air conditioning input as a temporary test to verify 
that the fan no longer turns on after a short delay. 

-

 

Verify that the air conditioning input is not being grounded or tied 
to +12v, unless the system is commanding it. 

Programmed values not 
being saved 

-

 

Make sure you pressing the 

Prg

 button to save values, and not 

the 

Skip

 button.
