Road heating controller three-element control
Automatic control of optimal snow melting operation from three sensor inputs! Achieving efficient and waste-free road heating.
The RHC-51B is a road heating controller that adopts a "three-element control method" combining three factors: outdoor temperature, road surface temperature, and road surface moisture. It automatically switches between "preheating operation," "anti-freezing operation," and "snow melting operation" according to road conditions, reducing unnecessary power consumption by operating only when needed. Additionally, it has high reliability that allows for emergency operation to continue through power control even in the event of a sensor malfunction.
