The GX 850M Controller is the most optimal solution for keeping an area free of ice and snow. The GX 850M acts on information received from sensor(s) which register both temperature and moisture, then calculates the information ensuring that the heat will only be turned on when snow and/or ice is present. The result is optimal performance with maximum energy savings and minimum operating costs.

•User interface allows total control of snow melting system set points

•Set to maximum melting or maximum energy savings or anywhere in between

•Dual zone feature allows for energy savings and lower amperage requirements

•Digital sensors provide precise feedback on snow and ice conditions

•Fault finding program detects and alarms on faults

•Can be field upgraded to take advantage of new features

•Requires at least one ground or roof snow sensor

•Allows up to four (4) sensor inputs in total
