ADDITIONAL INFORMATION
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 RH by 1%.
The Digital Humidifier Control will accurately control the
humidity in your home to a maximum of 45%.
The humidity values in Table 2 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.).
