IMPORTANT
The Control Module utilizes an auto resetting circuit breaker to protect
the fan(s) and controller circuit. In the event of an electrical short, the
breaker will “trip” and open the connection between the battery and the
controller. If this happens, turn the vehicle off and let it cool before
restarting the system. The breaker will automatically reset.
MAXIMUM CAPACITY AMPS:65
HOW IT WORKS
The Derale Control Module is designed to adjust the electric fan speed to maintain the engine temperature.PWM desired
The Control Module has an override circuit available that when activated, will ramp up the electric fans to 60% running speed. As theAC
engine temperature increases the fans will increase accordingly .
If the override circuit is not being used for the AC, an optional toggle switch could be connected to it to manually activate fans at 60%.
PWM will automatically increase fan speed if needed to maintain temperature.

THERMOSTAT PROBE INSTALLATION
Placement: The Thermostat Sensor is designed to be installed on the outlet side
of the radiator, therefore sensing the cooler fluid returning to the
engine. (See Diagram #4)
Warning: Do not install the Thermostat Sensor on the Hot side
s.of the radiator, Waterneck or Cylinder head
Installation:
1. TaketheRadiator Probe and thread it clockwise onto theThermostat Sensor.
2. Carefully insert the probe assembly into the fins of the radiator until Sensor is
flush with radiator. (Probe should not make contact with AC condenser or
auxiliary coolers. Probe may be trimmed to allow clearance.)
3. Install the Foam Pad onto the Radiator Probe.
4. Install Retaining Clip onto the Radiator Probe until tight. (See Dia. #5)
5. Route the Sensor Probe wire to the Control Module. The Sensor Wire splits
into two wires near the end. Using a Red # Ring Terminal, connect of8 either
the wires nto the Negative (-) Sensor Terminal on the Control Module.o
6. Using a Red #6 Ring Terminal, connect the Probe wire nto theremaining o
positive (+) Sensor Terminal on the Control Module. (See Dia. #7)
Note: Sensor Wires are not polarity specific. Sensor Wires can be lengthened if
necessary. When lengthening wires always use good quality wire &
connections to assure proper function.
CIRCUIT BREAKER MOUNTING
1. Choose a convenient location for the Circuit Breaker that is between the Fan
Controller and the Battery.
2. Using the breaker as a template, mark and drill two 5/32” holes.
3. Using the two #10 sheet metal screws supplied, secure the Circuit Breaker
in place.

this wire to the fan (-) terminal of the Module using #8Yellow Ring Terminal.a
Green Wire: Override Circuit (Optional)
The green wire is designed to work in two different configurations. When used, this will allow the Electric Fan(s) to be turned on
regardless of the temperature of the thermostat. The fan speed will quickly ramp up to 60% and will operate between 60 and
100% as the temperature increases. Use of the Override terminal is optional and not required for the Control ModuleNote: PWM
to work properly.
1. A/C Override - Using the provided, attach the green wire to a Positive (+) 12V output on theBlue Wire Tap Connector A/C
compressor.
2. Manual Switch Override - Attach the Green Wire to the 12V output on the manual switch (not provided).

TEMPERATURE ADJUSTMENT
The Control Module is set from the factory for use with a
180°F Engine Thermostat. If desired, the temperature can
be adjusted using the Multi-Turn Potentiometer on the
Control Module.
Reference Diagram #9
1. Using a standard Multimeter (set on voltage).DC
2. Connect the negative lead of the Multimeter to the
Negative (-) terminal on the Control Module.
3. Then connect the Positive (+) lead of the Multimeter
to the calibration terminal on the Control Module.
4. Using a small screwdriver turn the Multi-Turn
Potentiometer on the Control Module until the
Multimeter reads the desired voltage.
5. Using a 3/32” Allen Wrench, Reinstall the Control
Module cover.
VEHICLE TESTING
1. Before you start the vehicle, make sure all wires are safely zip tied and away from any moving parts.
2. Start the vehicle.
3. If the Manual Override function is being used, turn on the A/C or Manual Switch. Electric Fan(s) should start running
immediately.
4. Turn off the Manual Override or A/C function & allow the engine to warm up.
5. If the electric fan does not turn on or you feel that it is not set correctly, check all connections and refer to the “Temperature
Adjustment” Section above.
6. Once you have the fan cycling on and off using the control module, take the vehicle for a short test drive. For personal
preference, some additional adjustment may still be necessary.

Warning: Installation of accessories should only be undertaken by those with mechanical knowledge and are familiar with working on
vehicles. Always use eye protection (goggles, safety glasses or shield). Park the vehicle in a well lit area, on level ground and apply the
parking brake. Only work on a cold vehicle that has been sitting overnight, failure to do so will result in severe burns and injury. Before starting
the vehicle, make sure no tools or any other items are left under hood that could interfere with or be drawn into moving parts of the engine.
Failure to follow instructions can lead to severe damage and personal injury.
