The Humidifier Control is a precision instrument that can be used
to determine the RH accurately in your home during the winter. Turn the
dial to the lowest setting, then reverse the dial direction slowly until a
"click" is heard° At this point, read the RH on the dial. This will be very
close to the actual RH in your home.
To check the humidifier operation, set the humidifier control
above the click point, make sure that the water saddle valve is open
and that there is electricity to the humidifier_ Generally, the furnace
and blower motor must be operating for the humidifier control to
function. After the humidifier has operated for several minutes and
water is entering the humidifier and coming out at the drain, reduce
the humidifier control setting below the click point and the humidifier
should automatically shut off. Now set the humidifier control dial at
the recommended inside relative humidity, depending on the outside
temperature. Follow the suggested settings prior to a drop in the
outside temperature.
Additional Information
Be sure to keep fireplace dampers closed when not in use.
They provide an excellent escape route for heat, as well as humidit¥o
Humidity is lost at an even faster rate than heat because water vapor
tends to seek its own level and your humidifier would not be able to
replace it even when running at full capacity.
On occasion, indoor moisture producing activities such as clothes
drying, cooking, showers, etc., may raise the relative humidity level
higher than it should be, even though the Humidifier is not operating.
Telltale indications, again, 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.
