if there is no call for humidity. See “Check the Humidifier Operation” on
page 13.
ADDITIONAL INFORMATION – AUTOMATIC MODE
Your humidifier is a precision system that will accurately maintain the
humidity in your home. For every 2°F change in outdoor temperature, the
Digital Humidifier Control will automatically adjust the indoor humidity by
1%.
The Digital Humidifier Control will accurately control the humidity in your
home to a maximum of 45%.
The humidity Values in Table 3 are targets based on outdoor temperature
and the Digital Humidifier Control setting. The actual humidity may vary due
to conditions in the home (cooking, showering, etc.).
