Question about Aprilaire 600 Humidifier
My Aprilaire 600 appears to be operating properly, however,the humidistat never registers above a "1". FYI-The unit is attached to the intake ductwork and the humidistat is also mounted on the intake ductwork.
There are 3 things to check on the humidifier. Check the metal mesh screen, is it wet after the humidistat is call? If it is dry the water solenoid my not be opening or the nozzle is plugged. The circulating fan blows air through the wet screen to add humidity. Does the fan spin when the humidistat is calling? There is an intake and exhaust on the humidifier. Check that the metal was cut out properly when the humidifier was installed to allow air to feely circulate?
