PD PRO (23736) Automatic snow and ice melting system control

Utilizing standard ETI snow and ice sensors (sold separately), the automatic Snow Switch® Model PD Pro control is used in 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. The CIT–1 sensor may be roof or mast mounted and can be paired with the GIT–1 sensor for gutter applications or the SIT–6E sensor for pavement 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.
