IMPORTANT NOTES!
This fan controller has been completely quality control tested prior to final packaging.
If for any reason you are having issues with the installation of this fan controller,
please refer to the TROUBLESHOOTING section on pages 3 and 4 or view our tech tip videos
on our website. Please go to and search Part # 16795Derale.com

MAXIMUM CAPICITY: 65 AMPS
This controller will operate multiple fans with a combined maximum amperage up to 65 amps. On dual fan applications, it is
important to know your fan(s) amp draw before installing, if fan(s) exceed the 65 amp rating, you will void the warranty.
AUTO RESETTING CIRCUIT BREAKER
The fan controller utilizes an auto resetting circuit breaker to protect the fan(s) and controller circuit. In the event of an electrical
issue, the breaker will “trip” and open the connection between the battery and the controller. The circuit breaker will
automatically reset once the issue has been corrected.
MAIN POWER CONNECTIONS
The positive and negative wires feeding the fan controller be connected directly to the vehicles battery.MUST
This is very important because the controller requires a clean signal, do not connect directly to the fuse panel, starter or the
alternator.
VEHICLES BATTERY LOCATION
If the vehicles battery is located more than 5 feet from the fan controller, the signal could encounter some interference or noise,
which causes a dirty signal. In some cases, an additional filter may be required. Please contact our technical support team for
more information. (323) 266-3850 or dp_tech@derale.com
SENSOR LOCATION
The controller is designed to monitor the coolant going back in to the engine, therefore controlling the engine temperature vs.
reacting to it. By design, the sensor be installed on the of the radiator tank.MUST COLD SIDE
This unit is equipped with a newly released aluminum temp sensor that reacts 50% quicker than previous models. It uses 3M
double stick tape to adhere right to the radiator tank, therefore getting a very accurate temperature reading. The surface
preparation is critical; surface must be absolutely free of dirt, oil, peeling paint or any contaminants to ensure a proper bond.
Important: The ideal application temperature range is 70°F to 100°F (21°C to 38°C).The minimum suggested application
temperature is 50°F (10°C). At 70°F approximately 50% of the ultimate bond strength will be achieved after 20 minutes, 90%
after 24 hours and 100% after 72 hours.
OVERRIDE CIRCUIT
The fan controller has an override circuit available that when activated, will ramp up the electric fans to 60% running speed. As
the engine temperature increases the fans will increase accordingly.
WIRE CONNECTIONS
Crimp connections are critical to the function of this controller, please ensure that all connections are made using quality
crimpers. After each crimp has been completed, wiggle wires, there should be no movement within the connector.
