Watts 654 is a versatile snow melting control system that provides automatic and manual operation, allowing you to customize snow melting based on your needs.

Automatic start and stop operation: The 654 automatically starts melting snow or ice when detected by a snow sensor and stops when the surface is dry, ensuring efficient and effective snow removal.

Manual operation: You can also manually start the snow melting process using the Melt key on the control display, giving you complete control over when and how long the system operates.

Multiple zone control: The 654 can control multiple zones, allowing you to customize the snow melting operation for different areas. Zones without sensors can repeat the run time of a primary zone, ensuring consistent melting across your property.
