HUMIDIFY
Choose Humidify from the Main Menu.
The three items available in this menu are explained below.
Mode choices are:
Off – Humidity level will not be controlled through the thermostat.
With Heating – Humidification will occur only during a heat cycle and when the indoor humidity level
falls 2% below the humidity setpoint.
Independent Of Heating – Humidification will occur when the measured humidity level falls 2% below
the humidity setpoint regardless of a call for heat.
NOTE: Setpoint is only an option when an outdoor sensor is installed.
Setpoint choices are:
User Adjust – Humidification will occur based on the user setting.
Automatic – This selection can be made only when an outdoor sensor is connected. Humidity
setpoint is based on the outdoor temperature and the dew point adjustment (see below).
Notes: If Setpoint is set to User Adjust, Humidify Below will be the option on the Humidify Menu.
If Setpoint is set to Automatic, Dew Point Adj will be the option on the Humidify Menu.
Humidify Below – This is where you set your preference of the humidity level. The range is 15%
to 45%.
Dew Point Adj – Range -15% to +15%. This feature is typically used to help prevent condensation
from forming. In general, the lower the outdoor temperature, the lower the humidity level must be to
avoid condensation. Because each house has different tightness
characteristics, the Dew Point Adj setpoint may need to be adjusted
to optimize humidity control.
NOTE: When humidification is active, the main screen will include the
icon next to the measured humidity.
