The APS–3C Snow Switch, when used with compatible sensors, automatically controls snow/ice melting heaters, ensuring minimum operating costs. Typical applications include pavement, sidewalks, loading docks, roofs, gutters, and downspout snow/ice melting. The APS–3C is interchangeable with earlier APS–3 models.
The adjustable hold-on timer continues heater operation for up to 10 hours after snow stops to ensure complete melting. The optional RCU–3 Remote Control Unit can be located where system operation can be conveniently observed. It duplicates many of the controls and indicators on the APS–3C front panel and is used to clear tracked and drifting snow that may not land on a sensor.
The calibrated high-limit thermostat (40°F to 90°F / 4°C to 32°C) prevents excessive temperatures when using constant wattage and MI heaters. It also permits safe testing at outdoor temperatures too high for continuous heater operation. The temperature sensor is included.
The APS–3C provides a relay closure interface for use with energy management computers (EMC). This feature can also be used for general-purpose remote control, annunciation, and other advanced applications.
All sensor and communications wiring is NEC Class 2, which simplifies installation while enhancing fire and shock safety. The APS–3C can interface with up to six sensors from the CIT–1 product family. Using more sensors provides superior performance by better matching the controller to site requirements.
The APS–3C is an exceptionally capable deicing controller.
FEATURES
- Automatic snow/ice melting control
- Operates electrically- and mechanically held contactors
