Note that because the unit has no ON/OFF power switch, power runs to the unit as soon as
facility power is connected to it. For as long as power is running to the unit, the green SUPPLY
LED will always be lit. The unit initiates a heating cycle when the system sensor(s) detect snow
or ice at or below 38°F (3.3°C).
Upon initial Start-Up, all of the LEDs will come on for 2.5 seconds, and then shut off for 2.5
seconds. After this, the device goes into normal operation.
