Recently had a Aprilaire 700 humidifier installed by service technician that burned out after less than 1 year. New service technician informed me that the unit burned out because of being incorrectly wired. was told that the 24 volts from the humidifiers should not have been wired to 24 volts to the furnace. And should have only been wired to the humidistat As I have no background experience here I am Not sure if this was the case or not please comment
