prevent the floor from becoming too hot on long heat calls.

Cold Weather Comp: Modifies the humidifier output to prevent
condensation on the windows. Requires an outdoor
temperature source (CHV-THSAT or CHV-TSTAT with
CHV-RTHS, CHV-RTS or CHV-RSS, sensors sold
separately).
Invert Hum Output: Reverses the logic controlling the
switching of the HUM relay (NO/NC). May be useful when
using to control a dehumidifier.
NOTE: Most dehumidifier applications require the default
setting.
Call FAN in HUM: Makes a fan call during humidity calls
instead of waiting for a heating or cooling call to trigger fan.
NOTE: Most dehumidifier applications automatically trigger
fan operation.
NOTE: This setting is only useful for humidity calls with
normal (non-inverted) logic.
