AUTOMATIC MODE
In Automatic Mode, you will receive the optimal amount
of humidity so that your home and its furnishings will
be protected from the potentially damaging effects of
excessive or insufficient humidity during the heating
season The thermostat automatically adjusts your
home's relative humidity based on the outdoor
temperature to provide as much humidity as possible
while avoiding window condensation
The humidity setting needs to be set low initially to
determine the humidity limits of your home. Please
follow these steps when adjusting your thermostat
1. Adjust the humidity setting to 3, which is within the
low-normal range. During the next 24-48 hours, it may
be necessary to adjust the setting for more or less
humidity, depending on your personal comfort and
home's construction
2. During the coldest days of the first heating season,
minor adjustments may be necessary This will depend
on your home's windows and overall insulation The
relative humidity in your home will then be accurately
controlled to meet your needs and should not need
any adjustment during future heating seasons
