- Page 4 • A brushed DC motor MUST be connected to the fan output or the unit will report an error code. Possible use with very low power (<4A) fans and non SPAL products may also cause fan not found error code. SPAL USA will not guaranty this products function- ality with NON SPAL fans as too often specifications are unknown.
- Page 5 Pulse Width Modulation tech- nology. A second fan can be added but requires the use of an additional relay to control the secondary fan (SPAL part number FRH). The secondary fan will not be variable speed; it will be ON/OFF only.
- Page 6 Operation ENTR PRG STAT FAN Front View of PWM The FAN-PWM is equipped with 2 LED’s: a ‘STAT’ LED and a ‘FAN’ LED. ‘STAT’ LED will be lit when the unit is powered on, system checks are OK, and the fans are not running. The 3 color ‘FAN’...
- Page 7 GREEN, and the fan will stop completely. Mounting The SPAL FAN-PWM is water resistant and can be mounted in the engine bay or inside the vehicle. Keep the controller away from high heat sources such as the engine exhaust. Above the wheel well, on the radiator support, or firewall are good examples of proper locations.
- Page 8 • Please see the PROGRAMMING section on pages 11-14. • If using this type of sensor, the SPAL FAN-PWM must be programmed to your desired temperature points as the default settings will not be properly calibrated.
- Page 9 This sensor should be located in the en- gine for optimal performance. • When using the SPAL temperature sensor, the fan controller has a factory preset with a Low setting of ~190° and High setting of ~205°.
- Page 10 Air Conditioning Input The FAN-PWM has a built in 15 second delay for ON and a 30 second delay for OFF with the Air Conditioning Input. After the A/C compressor has turned ON, the fan will not go to HIGH until after a 15 second delay. After the A/C turns off, the fan will stay on HIGH for 30 seconds before resuming normal operation.
- Page 11 Air Conditioning Input (continued) 2. If your A/C system has a trinary switch, you may use it to trigger your cooling fans. This is the preferred way to control your cooling fans as the fan operation is based on the pressure of the coolant in the A/C system. Though the A/C pump may not be running, the pressure of the A/C system A/C TRINARY DIAGRAM may require operation of the cooling fans to properly cool the A/C condenser.

- Page 15 Programming (continued) The FAN-PWM has 3 default programs for use with the SPAL temperature sen- sor (FAN-PWM-TS). Preset 1 has a LOW temp of 170° and a HIGH temp of 185°. Preset 2 has a LOW temp of 190° and a HIGH temp of 205°.

See info under High and Low Program Data Error for more information on sensor issues. If using SPAL sensor did you cut the sensor harness connector off? If the sensor connector is cut off then you have to splice the white wire to the green wire. - Page 23 Possible use with very low power (<4A) fans and non SPAL products may also cause Fan Not Found Error code. SPAL USA will not guarantee this product’s functionality with non SPAL fans as too often specifications are unknown.
- Page 24 Troubleshooting (continued) CODE 3: High & Low Program Data Error (continued) 2. Using Factory Coolant Temperature Sensor (OEM) or Electric Water Temperature Gauge a. Sensor profile not compatible with current LOW/HIGH values. Depending on the application a minimum spread of 10°to 15° may not be sufficient.
- Page 25 Over current protection means that the output will SHUT DOWN if the mea- sured fan continuous run current increases above 30A for extended periods. If running a fan that is approaching this amount of current draw (>25A), SPAL USA recommends that the installation also include a status light so the operator will be aware of the fan status.
- Page 26 My Temperature Settings Are Not Staying Programmed. After programming the Low and High temperature settings make sure you are not pressing the ENTR button when ‘FAN’ LED is Blinking GREEN. If the ENTR button is pressed after programming, the FAN-PWM is set to a factory default setting erasing your previous settings.
- Page 27 (continued) Second Fan Will Not Turn On 1. Check relay wiring 2. Confirm ground signal from FAN-PWM on Gray wire when on High 3. Verify fan is working properly by grounding the gray wire from the relay and turning the ignition on, fan should run at this time. Fan Does Not Go Into High Mode Immediately After The A/C or Manual Override Is Turned On 1.
