MENU B – SETPOINTS continued
Hum Setpoint: This set point is used to control the return air humidity. The range
of adjustment is 25 to 70% with a default value of 50%.
Hum Deadband: This is the amount humidity must rise above the set point before
dehumidification mode will start. It is also the amount humidity must drop below the
set point before the humidifier will start. The range of adjustment is 1 to 15% with a
default value of 3%.
Note: This screen is only shown when "Hum Anticipation" is enabled in the factory
settings menu.
This screen shows information of what the current humidity setpoint is and how
much it is currently being offset by based on the difference between the
temperature setpoint and the actual temperature of the return air. In the Humidity
Anticipation mode, humidification control uses the "Anticipation SP" value rather
than the actual Humidity Setpoint.
