The DS8 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 DS8 will control a single 30 amp circuit at 277 volts.

DS8 units operate 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 DS8 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 DS8 & DS9 heat cable controllers detect snow and rain in addition to directly controlling the cables themselves by pushing power into the cable only when called for. The DS8/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.”

The Free Shipping option uses available “standard” delivery methods for whichever carrier services your location. For many that means UPS ground, but for locations that UPS doesn’t go to –or is too expensive, we substitute a different carrier.
We are based in the Twin Cities (Minneapolis/St. Paul) metro area, so depending on where you are located, your shipping time will vary.
Here’s A link to shipping distances with Approximations of Lead times
If you can’t wait for your product to arrive via UPS ground, Radiant Solutions also offers a paid, 2-day shipping option. One thing to keep in mind: our cables are fairly heavy, which mean they are expensive for us to ship. This means that they are even more expensive to ship expeditiously. A little bit of planning ahead can save you some good money.
And if you are using Heat Tape Pro on your roof / eave to resolve an ice dam issue, you should use heat tape to make sure there’s a clear path through your gutters for water to escape your roof. If you don’t do that, the water could just refreeze in your gutters. You also want to get the downspouts too.
There is a common misconception that gutters are a root cause of ice dams. This misconception can lead people astray when creating their strategy for ice dam deterrence. If you have an overhang on your roof (an eave), the chances are very good that you problem exists on your roof before the gutter.
The terms heat cable, heat tape and heat trace are all used interchangeably to described heated cables used to protect pipes from freezing, preventing roof and gutter ice dams from forming and for safeguarding temperature sensitive components.

Installing our heat tape on your standing seam roof can be very effective in combating ice dam formation. There’s two main products used to install heat tape on your standing seam metal roof: The S-5 SR Heat Tape Clip, and the standard ice dam heat tape clip.
Installing Heat Tape on a Standing Seam Roof with the S-5 SR Heat Tape Clip
The S-5 Heat Tape Roof Clip is a new, patented roof clip design specifically for standing seam applications with a focus on ease of install and effectiveness. It is used in conjunction with the S-5 Base, which needs to be purchased separately. The S-5 base is designed to clamp onto the seam of a metal roof as the S-5 Clip holds your ice dam heat tape into position. Can be set up in a single or dual-clip configuration. (See product page for more info)
Installing Heat Tape on a Standing Seam Roof with Standard Roof Clips
There are specific ways/configurations used when installing heat tape on a standing seam / metal roof using standard heat tape clips. The following (2.6 – figure 16.0 & 17.0) shows a snippet of the HeatTape Pro installation manual showing two different clip configurations, more info can be found in the manual itself: Heat Tape Pro installation Manual
