For nearly three decades, tekmar has been providing zoning and control solutions for a variety of heating and cooling applications. Products made by tekmar can improve the efficiency and comfort delivered by almost any system. The 665 Snow Detector & Melting Control is for single zone snow melting systems. This control operates a boiler and a system pump to provide a water temperature for your snow melting slab. An electrical cable contactor, or an injection pump or valve, may be operated in place of a boiler. The tekmar 665 is an ideal solution for safe and reliable snow melting operations.
The tekmar 665 monitors outdoor temperature information and the water temperature at a point in your system. Using this information, it is able to determine the ideal slab temperature for your snow melt system.
The tekmar 665 Snow Detector & Melting Control supports an additional sensor for automatic activation of melting protocols. A tekmar Snow/Ice Sensor is necessary for this functionality. Automated snow melting means that your system won't miss precipitate and won't run when there is no need.
Warm Weather Shutdown
Warm weather shut down is present in this control and it prevents your system from melting or idling when the slab and outdoor temperatures are above a threshold. That threshold may be automated or manually set.
Cold Weather Cut Out
Cold weather cut out prevents your system from running during extremely cold temperatures when maintaining melting functions may be inefficient and untenable.
Pulse Width Modulation
Pulse width modulation output will vary the run time of your device depending on the size of the difference between the current and desired temperatures. This feature limits the frequency of overshoots and undershoots, which means that your system will use less energy and your water temperature will experience less fluctuation.
