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.

Measuring is not difficult and you can make measurements without going up on your roof or using a ladder if you err on the side of overestimating the distances. Here’s Radiant Solutions Guide to Measuring for Heat Tape, which gives a detailed overview of measuring and some tips and resources, if you think you need it.
Once you have your measurements, you can use our Heat Tape Calculator to help you determine the length of Heat Tape Pro you need, the number of Heat Tape Clips you’ll need, and misc. product considerations.
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.
This includes, but is not limited to:
The type of roof you have determines the roof clips and accessories needed. Check out our Heat Tape Installation Accessories.

We generally do not reserve stock for miscellaneous reasons outside our stated inventory on this website. Besides selling on this website, we also Sell our products on Amazon.com – in doing so, we send separate inventories to their warehouse for fulfillment, so you could check inventory of the product you are looking for there.
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.
