Our systems can handle low temperatures, but many controls come equipped with a Low-Temperature Lockout Feature. This feature prevents the system from running in very low temperatures. At very low temperatures it can become difficult for the system to effectively melt the snow. It is however possible to turn off this feature should you need the system to keep running during such low temperatures.

All of our automatic controllers have a Hold-on time feature after the initial warming up of the snow melt system. This feature ensures that all the snow is melted from the surface, and also that the system continues to operate and evaporate the surface water without it refreezing.

When the design requirement's amp draw exceeds the selected controller's capacity.

Each zone may be activated for any length of time. No two applications are the same. You can start with 10 minutes and adjust up to 59 minutes per zone, and through trial and error, find the optimum zone durations for the best operation of your system.

Pavement Snow and Ice Sensor Kit (SIT–6E Sensor + Housing) and Snow Melt Aerial Sensor (AIR-SS-2).

The system may be shut off by pressing the OFF/CONFIG tab on the screen.

2 people found this helpful Was this helpful? Yes No

Yes. When more than one sensor is used, any positive activation by either of the sensors will activate the controller.

For example, the AIR-SS-2 aerial sensor and the SC-SS-PAV-6E-KIT slab sensor can be connected simultaneously for increased reliability.

If the “SNOW SENSOR OVERRIDE” button is pressed, the system will run for the set amount of time which was programmed in to the user defined “AFTER RUN” field.  To cancel the “SNOW SENSOR OVERRIDE” you must turn the system “OFF”.

This control is capable of controlling up to 4 separate zones.

Once you've decided what type of heating system (manual vs. automatic), you'll need to choose a control, which may or may not utilize a sensor. You may need a relay panel(s) depending on the size of the system, and a snow melt plaque which is required by the National Electric Code. Junction box(es) may be optional depending on the distance of heating cable from the indoor power location.

It depends on how the system is intended to operate. If the expectation is manual operation (ex. WiFi or Timer Control), then no sensors are required. If the expectation is automatic operation, then the system will require at least one snow sensor.

No, you may vary the times for each zone as necessary.

Ground fault equipment protection (GFEP) is intended to provide protection for equipment against damaging line-to-ground currents by disconnecting all ungrounded conductors of the faulted circuit.

2 people found this helpful Was this helpful? Yes No

No, a sensor is not required with the snow melt system. However, certain automatic controllers require a temperature/moisture sensor to sense atmospheric conditions and may also require an in-slab, high temperature limit sensor to be installed (notably, asphalt installations).

1 person found this helpful Was this helpful? Yes No

The "Max Slab Temp" sensor value should be set to 50 degrees F, and adjusted as necessary to optimize operation.

1 person found this helpful Was this helpful? Yes No

This control does not incorporate a built in GFEP protection. GFEP protection must be supplied by GFEP breakers.

1 person found this helpful Was this helpful? Yes No

No, the RCO can only be used with the SCA-DUAL or the SCP-120 snow-melting controllers.

1 person found this helpful Was this helpful? Yes No

No. multiple sensors can be used, but when they activate, the entire installation activates and the control will start controlling the entire installation (all zones attached to the control).

1 person found this helpful Was this helpful? Yes No

Ensure that all the zones have a time value set for run-time operation. If a time value is not set for a particular zone, it will not activate.

A 2 pole single-phase 240V circuit works by continuously monitoring the current flowing through both hot wires of the circuit. If it detects even a slight imbalance between the current on each hot wire (indicating a ground fault), it will quickly trip, cutting off power to the circuit. Essentially, it compares each leg of the 240V circuit and trips if they are not precisely equal.

This feature prevents the snow melting system from running, by default, in temperatures below 17°F (–8.33°C), or as set by the user. At temperatures this low, it becomes difficult for the system to effectively melt the snow. It is, however, possible to turn off this feature should the system be required to keep running during these low temperatures.

Priority leaves off where it last ended. So if the controller shuts off in PRI3, that's where it will start again when the snow continues, or it is manually triggered. It will pick up exactly where it left off. Same zone. Same remaining time and after run time.
