Description
The M326CDP Controller brings control and monitoring of your snow melt system indoors. No need to hope that the system has successfully triggered. One glance at the CDP confirms it! The CDP is compatible with all M326 activators/controllers.
The unit consists of an electronic printed circuit board mounted securely to a steel mounting plate. The overall dimensions of the CDP are 4.1″(104) x 1.8″(45) x 0.9″(23). The unit weighs 2.5 ounces. The CDP fits into a standard single gang or multi gang electrical enclosure. Compatible self-threading mounting screws that fit both metal and plastic enclosures are included. The plate also has mounting holes for a rectangular “modular” cover plate, similar to the Leviton Decora® or Hubbell StyleLine™ series. This allows the user to select a cover plate color and material that blends with the decor of the room.
Wiring is performed by installing an interconnect cable between the CDP and the companion M326 activator. All signals between the units are very low voltage so no conduit or similar protection of the interconnect cable is required. The individual leads of the interconnect cable are then installed into the rear terminal block of the CDP and the unit is ready for operation. The CDP does not require batteries or an AC power connection. It is actually powered by parasitic voltage “stolen” from the snow sensor. Peak power consumption is only 3.5 milliwatts. Operational temperature range for the electronic components is -40oC to +85oC. Therefore, the CDP can be installed indoors or outside with proper protection from the elements.
The M326CDP Controller allows control of the snow sensor and also reports the sensor’s own override switch position. The “Manual On” function activates the snow sensor and controlled equipment to operate for one “delay off” cycle. The delay off cycle is determined by the DEL switch setting and the DEL adjustment on the snow sensor, 2 minutes in “sensor” mode, 30-90 minutes or 2-6 hours in “controller” mode. This can be handy for testing and special operational conditions, like clearing hail buildup or heavily drifted snow, without the potential expense of leaving the system in a continuous “Manual On” condition. The “Automatic” position allows the sensor to handle all detections and control. The unit will also always revert to “Automatic” mode once a “Manual On” cycle has been completed. A sensor will report activation by illuminating the “Deice On” indicator. The “Standby” position disables triggering even in snow conditions and can also be used to clear the delay off timer from true or test activation.
