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 employs a "three-element control method" combining three factors: outdoor temperature, pavement temperature, and pavement 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 a high level of reliability, allowing for emergency operation to continue through power control even in the event of a sensor malfunction.
