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.”

We are building a hand guide to identify what kind of roof you have and find the clips that can/should be used with that roof-type.

We have a guide on How to Measure for Purchasing Heat Tape that will help you. Once you have your measurements, you can find our Heat Tape Calculator here.
Heat Tape Pro and Pipe Freeze Pro are offered in many lengths from 6-foot up to 150-foot. These products are not designed to be modified, so you should pick the length you need and work with that length. These cables should not be altered and doing so would void any warranty on the product.
We offer heat tape on spools from 250-foot to 1000-foot. These spools are designed to be cut to length, made into multiple cables, etc. Heat Tape on spools needs to be hard-wired into a junction box, or have a power connection plug-in manually added to it for use. It also requires ends to be properly sealed and terminated. When working with Heat Tape on spools, a Licensed Electrician should be utilized to assure proper wiring per regional codes and standards.
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
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.
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.
Heat Tape Pro has the most comprehensive installation system that works on almost any kind of roof type.
