It displays both set and real-time temperatures in °F or °C on an LED screen, delays the second fan to prevent inrush overload, and fits most automotive, truck, and off-road cooling systems as a direct replacement for DC0444-style switches.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the controller manage two fans without tripping circuits?\u003c\/h3\u003e\n\n\u003cp\u003eThe FASTSTORM unit stages fan activation: Fan #1 starts immediately at the set temperature, and Fan #2 powers up after a ten-second delay to limit simultaneous current draw. Built-in relays matched to the supplied wiring harness handle common inrush currents for 12V and 24V systems, reducing strain on the vehicle's electrical system.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e10-second delayed start for the second fan to reduce fuse and relay stress\u003c\/li\u003e\n  \u003cli\u003eIncludes relays and wiring labeled for straightforward connections\u003c\/li\u003e\n  \u003cli\u003eSupports fans operating from 12–27V, suitable for dual-voltage applications\u003c\/li\u003e\n  \u003cli\u003eAutomatic shutoff when temperature drops 1°C below the set point\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat temperatures can I set and how is accuracy shown?\u003c\/h3\u003e\n\n\u003cp\u003eThe kit offers a wide, adjustable temperature window from 104°F to 230°F (40°C–110°C) to accommodate a broad range of engines and operating conditions.
