Watts 654 Quick Set-up

Brand: Watts

Model: 654

Type: Quick Set-up

Watts 654 is a snow melting control system that can be used in both interior and exterior locations. It has two relay outputs that can be used to control a variety of devices, such as snow melting mats, hydronic boilers, or electric snow melters. The system can be configured to operate in a variety of modes, including PWM (hydronic pulse width modulation), BOIL (hydronic boiler heats snow melting system), MIX (hydronic mixing valve or injection pump heats snow melting system), and ELEC (electric snow melt).
