snow switch SC-40C

Modular Snow/Ice Heater Control System

The SC–40C Satellite Contactor answers the need for cost effective modular snow melting heater control. One or more SC–40Cs, when used with an APS–4C Control Panel acting as the master control, allow for modular snow melting system design. There is no limit to the number of SC–40Cs that can be interfaced in a single system. This approach reduces front end design, hardware and installation costs while providing a number of useful features that would be otherwise too expensive and complex to implement. The SC–40C provides the same advanced patented and patent pending Ground Fault Equipment Protection (GFEP) as required by the USA and Canadian National Electric codes that is found on the APS–4C. Upon sensing a ground fault condition, an SC–40C inhibits operation of its contactor until manually reset. Circuits without a ground fault continue to operate normally thus partitioning defective heaters.

Snow switch GF Pro

SNOW AND ICE MELTING SYSTEMS CONTROL: AUTOMATIC WITH INTEGRAL GROUND FAULT EQUIPMENT PROTECTION

The Snow Switch® Model GF Pro utilizes standard Environmental Technology snow 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 GF Pro interfaces with up to two standard Environmental Technology sensors to meet site requirements. 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), saving energy and ensuring thorough snow melting. Since 1968, these sensors have been the industry’s most versatile and cost-effective automatic snow melting control sensors.

• Self-testing Ground Fault Equipment Protection (GFEP)
• Automatic and manual-override operator controls

Snow switch PD Pro

SNOW AND ICE MELTING SYSTEMS CONTROL: AUTOMATIC, PILOT DUTY APPLICATIONS

Utilizing standard Environmental Technology snow 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.

• Automatic and manual-override operator controls

snow switch EUR-5A

AUTOMATIC SNOW/ICE MELTING CONTROL PANEL FOR ELECTRIC & HYDRONIC APPLICATIONS

The EUR-5A brings the performance, economy and energy efficiency of the industry leading APS–3B to a wide range of commercial snow melting applications requiring electrical panel location. A rich assortment of features optimize EUR-5A performance for its intended applications and environment. The EUR-5A interfaces multiple sensors from the CIT–1, GIT–1, SIT–6E family for flexibility in a wide range of pavement, gutter and downspout deicing applications. This feature is essential for large systems employing common heater switching.

• Continuing heater operation
• RCU–3 Remote Control
• Low voltage push-button switch

snow switch APS-3C

Automatic Snow and Ice Melting System Control

The APS-3C Snow Switch when used with compatible sensors automatically controls snow/ice melting heaters, ensuring minimum operating costs. Typical applications include pavement, sidewalk, loading dock, roof, gutter and down spout 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. It is used to clear tracked and drifting snow that may not land on a sensor.

• High limit thermostat
• Relay closure interface

snow switch APS-4C

AUTOMATIC SNOW/ICE MELTING SYSTEM CONTROL INTEGRAL GFEP

The APS-4C Snow Switch when used with one, or more, compatible sensors automatically controls snow/ice melting heaters for minimum energy costs. Applications include pavement, sidewalk, loading dock, roof, gutter and down spout snow/ice melting in commercial and industrial environments. The APS-4C is interchangeable with the earlier APS-4. The adjustable hold-on timer continues heater operation for up to 10 hours after snow stops to ensure complete melting. The optional RCU–4 Remote Control Unit can be located where system operation can be conveniently observed. It duplicates many of the APS-4C front panel functions.
