The Uponor single-zone snow-melt control is a microprocessor used to control a hydronic system to melt snow and ice more effectively from exterior surfaces. This low-cost control solution provides snow and ice melting for both automatic and semiautomatic operation, using a Pavement Snow and Ice Sensor or optional Aerial snow sensor. The latter is perfect for retrofit applications when adding a Pavement Snow and Ice Sensor is not an option. The control also provides an idle mode and warm-weather shutdown/cold weather cutout, as well as modulating boiler control and optional boiler protection.
