Works with 12V and 24V systems
- Manages 1 or 2 fans with a 10-second delay for the second fan to prevent circuit overload.
- Enhanced cooling for high-performance engines, off-road vehicles, and trucks.
LED display shows actual and set temperatures in Celsius or Fahrenheit.
Heavy-duty 12AWG wiring and dual 40A relays (50A max current).
Dual Fan Control
Supports thermoelectric fans, EWPs (Electric Water Pumps), and similar models.
Precise Temperature Adjustment:
The default set temperature is 104°F. The system activates at 104°F and automatically shuts off when the temperature drops to 96°F. The fan automatically shuts off when the sensor temperature drops 8°F below the activation set point.
- Universal Fit & Simple Installation: Designed as a direct replacement for Part #0444/DC0444, this digital controller works seamlessly with Thermatic Electric Fans, EWPs, and most automotive cooling systems. The kit includes pre-labeled wiring and all necessary hardware for a hassle-free, plug-and-play setup.
- Precision Temperature Control with LED Display: Easily adjust the fan activation temperature from 104°F to 230°F (40°C–110°C). The bright LED screen displays both real-time and set temperatures in °C or °F—simply hold the button for 5 seconds to switch units. The system automatically runs the fans until the air temperature drops 1°C below your set point, preventing overheating and ensuring optimal engine performance.
- Smart Dual-Fan Operation with Staggered Start: Control one or two electric fans with ease. To protect your electrical system from power surges, the second fan engages 10 seconds after the first fan starts. This intelligent delay prevents circuit overload, making it ideal for high-performance engines, cars, trucks, and off-road vehicles.
- Heavy-Duty 40-Amp Relay Harness for 12V/24V Systems Built with a 40-amp relay and 12 AWG wiring, this harness safely delivers power to up to two electric fans. It supports both 12V and 24V applications and includes a 30-amp in-line fuse per fan for added circuit protection. Maximum continuous draw is 30 amps per fan for reliable, long-lasting performance.
- Versatile 3/8\" NPT Temperature Probe Included: The kit features a 3/8\" NPT thread-in temperature probe for easy integration into standard radiator or water neck ports. This ensures accurate coolant temperature readings for precise fan control.
