Operation The electric cooling fan controller provides a way to run up to two electric engine cooling fans or one two speed cooling fan. (A second relay, sold separately, is required for two speed or dual fan operation). The controller monitors the engine temperature using a dedicated sender, or a gauge and its sender. When the engine temperature goes above a user adjustable set point, the fan is turned on with a relay. When the engine has cooled below a user selectable off temperature, the

Set Up 1. Press and hold SW2, then turn the key on. 2. Release SW2, then press and release SW1 to move onto the next step. 3. To select temperature scale to use, press and hold SW1 to select (Fahrenheit) or press and hold SW2 for (Celsius). Hold the switch for longer than one sec to select. Once a temperature scale is selected, the display will flash and go on to next setting. 4. Display will now read indicating low fan on temperature is to be set. Use SW1 or SW2 to selec

Custom Calibration Note 1: If your engine is warm you may need to disconnect the wire from your sender in order get to the lower points on the gauge. Note 2: If the key is turned off in custom setup, the previous gauge setting will be used and the custom gauge will not be saved. Note 3: If your gauge does not have defined ticks with numerical temp readings, it is highly recommended to use a dedicated sender as calibration to the gauge is very inaccurate or impossible without temp marki
