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.

Yes. Heat Tape Pro can be used on your flat roof and will not harm the roofing material.

Radiant solutions has developed several accessories and installation components that work well for flat and low-pitch roofs. Installing heat tape on a flat roof often requires more unique considerations than standard serpentine patterns used on pitched roofs.

Check out our Case Studies for examples of Heat Tape installations, including information on flat roofs.

Also refer to the Heat Tape Pro Product Manual for information on flat roof installations of heat tape.

Yes!

Heat Tape PRO can be use with any gutter system made, be it open, closed, metal, plastic, vertical or horizontal.  Heat Tape PRO will work throughout the winter to keep an ice free path open for water so it can escape and move away from your home.

Keep in mind that if your home has ice dams in addition to ice in your gutters, you will want to install Heat Tape PRO on your roof to address that problem as well. Heat Cable in the gutters alone will not manage problematic ice on the roof surface.
