Hayden's digital fan controller incorporates pulse width technology. This unique controller varies fan speed based on your custom temperature setting giving cooling when needed, not when you don’t. With adjustable set points between 120˚F-210˚F, this digital controller has no contacts to wear out and no relays to replace, ever. Its auto on feature with A/C engagement and auto shutdown when key off ensures you get the cooling you need while extending fan life. Hermetically sealed electronics and EMI suppression ensure long life and trouble free operation. Temperature probe, wiring and installation instructions included.
Optional 3/8” MPT brass sending unit also available, Hayden part #355
