APS3C 120V Controller & Snow Sensor


Automatic snow/ice melting control

• Operates electrically- and mechanically- held contactors

for pilot duty applications

• Energy management computer (EMC) interface

• Accommodates MI, constant wattage and self-limiting

Multiple sensor capability

• Heater hold-on and test capabilities


• Simple to install and operate

• Low system costs

• Minimum energy costs

Up to 6 sensors from the CIT–1 product family not included  


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.

The calibrated 40ÅãF to 90ÅãF (4ÅãC to 32ÅãC) high limit thermostat 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 and annunciation and other advanced


All sensor and communications wiring is NEC Class 2. This simplifies

installation while enhancing fi re and shock safety. The APS–3C can interface

up to six sensors from the CIT–1 product family. Using more sensors

provides superior performance by better matching the controller to site

performance requirements.  The APS–3C is an exceptionally

capable deicing controller.


SNOW OWL Aerial Snow Sensor replaces the CIT-1 for surface snow and ice management systems.

The SNOW OWL is designed to work with a controller or contactor, optimizing energy usage in heated snow/ice melting applications. The SNOW OWL is also an excellent solution for building automation applications.

During dry or warm weather, the system’s heaters are turned off to save energy costs. The heaters are turned on only when snow and/ or ice is present, and kept on only long enough to ensure complete melting and drying. Temperature and time parameters can be varied within the SNOW OWL, enhancing system performance in a given environment and application.

Self Regulating Plug In Heating Cable 120V



Polymeric Freeze Protection Heating Cables are easy to install, reliable, and low-maintenance, making them ideal for residential free air applications like pipe tracing or roof and gutter de-icing. Pre-Terminated Polymeric Heating Cables come fully assembled from our factory in various heated lengths, with a 2’ cold lead and plug to transition from the heated area to your 120V receptacle.

These cables are engineered in a constant wattage/series-resistant design and include a built-in thermal disk that helps ensure the cable is on when cold and turns itself off when the pipe is warm enough not to freeze. This reduces energy costs and eliminates the need for external thermostat control. Further, the fixed wattage output means you will maintain consistent temperature across the entire pipe.

Self-Regulating (SR) Heating Cables


Self-Regulating (SR) Heating Cables are safe, flexible and easy to install in a wide range of residential, commercial, and industrial applications where the heating cables need to be exposed to free air, rather than being embedded in a medium.

Self-regulating technology allows each of these heating cables to adjust its wattage (heat) output based on the temperature and environment to which the cable is exposed. In cold conditions, it generates more wattage (heat). In warmer conditions, the output is reduced and, thereby, saves energy.

This technology also helps make it one of the safest heating cables on the market, as well as the industry standard for most roof and pipe tracing applications. If it encounters a warm surface or is exposed to a warm ambient environment, the cable will automatically adjust its wattage output and avoid overheating in any one location. They can also be cut, field-terminated, and crossed over themselves.

These cables are ideal for:
  • Freeze protection pipe tracing
  • Process maintenance pipe and vessel tracing
  • Heat loss replacement
  • Roof and gutter de-icing
  • Frost heave prevention
  • In-pipe heat tracing of potable water lines
  • Hot water temperature maintenance

Self-Regulating Heating Cables are available in bulk coils with termination accessories. However, you can also choose from our standard catalogue of pre-assembled SR cable kits that include a factory-made end seal and pre-made termination point. These have a 6′ cold lead and directly plugged into a 120V outlet.
