Oct 09, 2009 · Wiring Humidifier to furnace Showing 1-13 of 13 messages. Wiring Humidifier to furnace: elbrecht: the air conditioning relay. The blue wire is from the fan/limit control, the 110 volt side of a 24 volt transformer to a multi-speed blower, where speeds are determined by heating or. The line voltage feeding the furnace (to operate the fan blower motor) is transformed down to a safer level of 24 volts (the gas control valve needs 24 volts to open), and after making a series loop through at least one safety device (the most basic and mandatory one is an over-temperature shut down), the power goes up to the thermostat, and.
Once the wiring is completed, turn on the electrical power to the furnace, plug the ventilation unit and verify if the relay is working properly. When the ventilation unit is ON, the furnace blower.
