If your vehicle is not equipped with an OEM temperature sensor, you can pur-
chase a SPAL temperature sensor (SPAL part number FAN-PWM-TS) that plugs
directly into the fan controller harness. 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°.
• If different settings are required, please see the PROGRAMMING section
on pages 11-14.
The FAN-PWM provides a negative output for an external device such as a LED
(not provided) to be used to remotely show the status of the system. With the
vehicle's ignition on, the status output will indicate the following:
• No output: All checks OK, fan not running
• Output on: Fan output is active (fan could be running low to high speed)
• Blinking output: Indicates an error code; watch 'STAT' LED on module for
error code (See page 21)
