A fan or cooler relay is used in electrical furnace to change the blower speed to the blank speed for cooling
In an electric furnace, a fan relay typically changes the blower speed to a lower setting for cooling. This reduced speed helps to circulate air more gently, allowing for better heat dissipation and preventing overheating of the furnace components. By operating at a lower speed, the blower can provide effective cooling while maintaining comfort in the surrounding space.
