required.
Control
GC-1 (or a DS-8 substitute)
Enter Desired Quantitiy
*GC-1 prevents melted water from re-freezing
Monitors Temp & Moisture
*GC-1 prolongs the life of cable by allowing the cable to only turn on when needed
*GC-1 provides significant energy saving versus systems without a control
Enter Desired Quantitiy
Temp Sensing Only
C3RC
*C3RC is ideal for downspout only applications
Note: Most electrical contractors will have multiple runs of cables tied to contactors (holding the load of the SR Cable) and then the contactors are tied
to the control. Additional controls are recommended where cables will see different conditions (i.e.: temp, sunlight).
