ETI Snow Switch PD Pro

The Snow Switch Model PD Pro is an automatic snow and ice melting control system. Utilizing standard Environmental Technology snow and ice sensors (sold separately), applications include snow and ice detection and melting for pavement, sidewalks, loading docks, roofs, gutters and downspouts in commercial and residential environments.

The PD Pro interfaces with up to two standard Environmental Technology sensors to meet site requirements. The CIT–1, GIT–1, and SIT–6E sensors reliably detect snow and ice melting in gutter and pavement applications. The CIT–1 Aerial Snow Sensor detects falling or blowing precipitation before snow or ice begin to form, allowing the control to begin managing the system. Roof or mast mounted, it can be paired with either the GIT–1 Gutter Ice Sensor (gutter deicing applications) or the SIT–6E Pavement-Mounted Snow/Ice Sensor (trafficked surface deicing applications). All three sensors detect precipitation as snow at temperatures below 38°F (3.3°C). The PD Pro is signaled only if moisture occurs below this temperature, saving energy and ensuring thorough snow and ice melting. Since 1968, these sensors have been the industry’s most versatile and cost-effective automatic snow melting control sensors.

The PD Pro features automatic and manual-override operator controls. The adjustable Hold-On timer continues heater operations up to 8 hours after snow or ice conditions end to ensure complete melting. The Heater Cycle control button allows manual initiation or cancellation of a heating cycle. Use optional RCU–3 remote control unit for convenient monitoring and operation. These flexible control options provide complete snow melting and water evaporation for lower operating cost.

The PD Pro weighs only 3 pounds and measures 5 1/2" (L) x 8 1/8" (W) x 4 3/8" (H). Comprehensive instruction manuals simplify installation and operation. PD Pro controllers are backed by Environmental Technology Technical Support.

The PD Pro is a capable snow and ice control for medium-sized applications whose features and power requirements do not require an APS or EUR Series control panel.
