Overview
The Aprilaire 4851 blower activation relay is used to allow the humidifier to energize, or turn on the furnace blower in order to circulate humidity even when the heat is off. Typically, the humidifier runs when the thermostat activates heating. With this relay installed, however, humidification will be available at any time.
