How is a Hott-Wire system activated?
Hott-Wire snow melting systems are activated by a relay panel or contactor panel, which allows a single activation device to control multiple heating circuits simultaneously — essential for larger commercial installations covering thousands of square feet. Smaller systems can connect the activation device directly to the heating element without a separate relay panel. Automatic snow and ice detection sensors are the recommended activation method, triggering the system when temperature drops below 38°F and moisture is detected — eliminating the need for manual switching. More advanced activation methods, WIFI, weather-predicting, and BAS/BMS integration is also available.
