It can go outdoors provided weatherproof fittings are used. The optional RCO switch should be considered for remote operation from an indoor location.
The AIR-SS-2 can be mounted at a distance up to 500 feet away from the controller using 22-gauge wires and up to 1000 feet using 18-gauge wires.
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.
