Product Details

Dual Heat Tape Controller with Sensor (DS9-C)

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.

The type of roof you have determines the roof clips and accessories needed. Check out our Heat Tape Installation Accessories.

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.

Yes. Radiant Solutions Company is based in Hopkins, Minnesota.

We are a family-owned business with less than 10 employees that has been in business since 2016. Our experience with ice dams goes far beyond that: our founder Steve started a business diagnosing and solving Ice Dam problems on customer houses for almost 35 years.

The short answer is NO. Self-regulating heat cable does not turn itself on and off automatically. To do that you need to put the cable on a switched circuit or outlet or on a controller. Of course, you can also be old-school about it and simply plug and unplug as needed. 

“Self-Regulating” refers to the fact that these cables are temperature sensitive. Due to their construction, these cables sense changes in temperature along their entire length, demanding more power as temps fall and less when they rise. 

PipeFreeeze Pro™, Pipe Freeze Protection Solution has a built in thermostatic switch, meaning it will turn on and off on it’s own.

Heat Tape Pro™, does not contain a built-in thermostatic controller. We recommend adding the ThermaCord™ Thermostatic controller to turn your Heat Tape PRO to turn the cable on and off with changes in temperature.
