1. A snow and ice melt control system for use with a slab to melt ice and snow from the slab, control system comprising:
- a slab supply for supply fluid to said slab,a slab return for carrying fluid away from said slab after said fluid passes through said slab,said slab exposed to ambient outdoor weather conditions, temperature differential means to determine the temperature difference of the fluid supplied by the slab supply and the fluid returning from the slab,said temperature difference related to the ambient outdoor weather conditions,a controller connected to said temperature differential means to generate command signals responsive to the temperature differences between the supply and return fluids.

Abstract
A snow and ice melt control system is provided to melt snow and ice from a slab, a temperature sensor means are provided at the input and output from the slab, and a differential temperature is generated reflecting the condition of the slab in respect to the ambient temperature. A controller is provided to adjust the amount of heat and heated fluid flowing to the slab to actively respond to environmental conditions to more efficiently melt snow and ice on the slab.
