The DS9 turns hardwired heat cable systems on and off using both temperature and moisture, saving you a lot on your electric bill. This controller works with any Heat Tape PRO spooled cables from 6 watt to 8 watt, from 120 volts up to 277 volts. The DS9 will control TWO 30 amp circuits at 277 volts.

The DS9 unit operates by detecting environmental conditions through a base mounted temperature sensor and a remote heated precipitation sensor. When rain or snow land on the precipitation sensor, your cable system will turn on. The small heater in the sensor then rapidly evaporates the moisture, clearing the sensor in preparation for the next cycle. Smart stuff. The precipitation sensor is connected to a 10 foot cable and is intended for remote mounting near the roof deicing system. Use an EX-50 extension kit (with coupler) to put the precipitation sensor up to 60 feet away from the DS9 unit.
Signals from the sensor are supplied to the microcontroller which determines the appropriate action based on the system settings.
The difference between “sensor” and “controller” modes is the “Delay Off” drying cycle provided by each configuration. “Delay Off” time is the amount of time the sensor/controller will hold the load control relay(s) closed after the last detection of rain or snow. Proper setting of “Delay Off” assures that heat cables have created a sufficient melted pathway through the snow/ice on the roof.
The DS9 heat cable controller detects snow and rain in addition to directly controlling the cables themselves by pushing power into the cable only when called for. The DS9 is constructed of a durable NEMA 3R enclosure, rated for outdoor use and has a 3/4 Inch conduit hub and operates from -40F to +185F. The power pigtails are #14 Blue/Brown/Green and the load pigtails are #10 AWG Yellow.
“Heat Tape Pro did exactly what I needed it to do. Now I don’t have to worry about water leaking into my house, because I can tell when it’s working by the little light on the end of the cable.”

Including a thermostatic heat tape switch or controller in your installation will cut power to your heat tape in times it is not needed. This will lessen your environmental footprint and save you money.
Savings will always depend on the weather and how often you have temperatures above the threshold that the switch turns on your heat cable. In most situations where heat cable is needed, savings will offset the cost of the ThermaCord and then some.
