The dual speed model will run continuously on low speed. The integrated humidistat senses the humidity level of the room and boosts the fan to high speed when the humidity level rises above the preset level. When the humidity level falls below the preset level, the fan will return to low speed. The fan can also be activated to high speed through a wall control switch or timer.
