Changing the Humidity Level E The thermostats
offer three humidity options: normal, auto, and off.
The thermostat is set at the factory for "normal humidify,"
which is a fixed humidity setting based on how much humidity
the user wants in the space. This humidity level remains con-
stant, regardless of the outdoor temperature. The user can man-
ually adjust the humidity level according to their own prefer-
ences.
The second option, "auto humidify," uses an outdoor tem-
perature sensor (if installed) to automatically adjust the indoor
humidity level according to the outside temperature.
The third option is to turn off the humidify/dehumidify
feature.
To change the fixed (constant) humidity setting for normal
humidify, perform the following procedure:
1. Open the thermostat door.
2. The "humidify" icon will be displayed at the bottom of
the screen when the operating mode is heat. The "dehu-
midify" will be displayed when the operating mode is

ting. It is factory set at 26% for humidify and 60% for de-

value to a higher number. Humidity can be set to between
