Check the Humidifier Operation

Turn the control knob to the maximum RH setting.. Make sure that the water saddle valve is open and that the humidifier is on.. The indoor unit blower must be running for the humidifier to function.. Once humidifier operation is verified, reduce the Humidifier Control setting to the recommended inside humidity, depending on the outside temperature..

If using the automatic humidifier control model number

S1-HUSTATAUTO56, Do not leave in test mode as humidifier will not operate.

additional information

Be sure to keep fireplace dampers closed when not in use.. They provide an excellent escape route for heat, as well as humidity..

On occasion, indoor moisture producing activities such as clothes drying, cooking, showers, etc.., may raise the humidity level higher than it should be, even though the humidifier is not operating.. Telltale indications are condensation or frost on cold surfaces such as windows, doors, walls, etc.. If such condensation persists for several hours, your home should be ventilated to dissipate the potentially damaging excess moisture..
