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.”

PipeFreezePRO comes with one or more 30ft rolls of high-quality fiberglass tape, but you can use any tape with a temperature rating of 150º F and above. Self-adhesive aluminum foil tape can be used but avoid standard tapes, including electrical tape and duct tape because they lose their adhesion when exposed to heat. Remember, it’s imperative to cover the pipe/heat tape assembly with pipe insulation (1/2″ minimum thickness). Think four easy steps: 1) cable on pipe, 2) tape on cable, 3) insulation on pipe/cable and 4) tape on insulation.
Pipe Freeze PRO can be overlapped during installation. This is a fundamental advantage of self-regulating heat cable over cheap, constant wattage cable found in hardware stores is that it can be overlapped without risk of shorting out or catching fire. So yes, overlap away!
The amount of heat cable needed for pipe freeze prevention is determined by a couple of simple factors including: Length of pipe, diameter of pipe, distance to power supply and number of valves.
Most of the time, we do not recommend a spiral cable application because it’s simply not necessary. It requires 3x the cable to do the same job.
Therefore, simply use a straight, single run of cable affixed to the bottom of the pipe (think 6 o’clock position) using the provided fiberglass installation tape. Next, add 1 foot of cable for every valve because you will be wrapping the valve with cable. For pipes less than 1″ in diameter, a single cable run is sufficient. For larger pipes, two cable runs are recommended. Keep in mind that plastic pipes are less thermally conductive so you may choose to use two cable runs on larger plastic pipes to be safe. Finally, if your outlet isn’t close to the pipe you are treating, factor in enough heat cable to reach your outlet (Pipe Freeze PRO does come with a 36″ power cord).
Finally, you must install insulation on your pipe and heat cable assembly in order for the system to operate effectively. See instructions for further details.
The cable can be exposed to wetness but the thermostat must stay dry to function properly. Use Pipe Freeze PRO for pipe freeze prevention applications only.
Consider using Heat Tape Pro inside of open drain pipes as that cable is rated for use in wet areas.

Pipe Freeze Pro’s integrated thermostat turns power on and off automatically to the cable to save electricity. The thermostat is the lump located between the power cord and the heat cable. The thermostat triggers the cable to turn on at 37ºF and off at 50ºF, with a sensitivity range of +/- 4ºF. It’s a great feature that makes Pipe Freeze Pro unique among heat cables on the market.
Yes and no. The cable is approved for exposure to wet conditions but you should keep the thermostat dry for proper operation.
No. The thermostat need only be exposed to cold air. It does not hurt to have the thermostat attached to the pipe but it is not necessary. If you choose to attach it to the pipe keep in mind that the thermostat should not be covered with insulation.
No. You want the thermostat to react to the cold environment so it triggers the Pipe Freeze Pro to turn on.
Every Length of Heat Tape Pro has a cord length of 10-feet that is not included in the listed/state length. Meaning: A 100-foot Heat Tape pro will have a 100 feet of heated cable + a 10-foot unheated power cord.
Every Length of Pipe Freeze Pro has a cord length of 3-feet (36″) that is not included in the listed/state length. Meaning: A 30-foot Heat Tape pro will have a 30 feet of heated cable + a 3-foot unheated power cord.
Radiant Solutions has the most comprehensive installation system for Heat Tape that exists. We make accessories to install heat tape on almost any kind of roof.
