There are several modes on control. Winter is usually set at 35% and summer 50 to 55%. On the venting mode set 20/40. This will bring the unit on for 20 minutes and off for 40. The first mode is vent and you can use that when you have a lot of people over to bring in fresh air and exhaust old air. This is mode that will operate up to 8 hours. Low or medium setting on fan control. Russ

This unit is not a dehumidifier it only brings in and exhaust air from house. This units should be connected to bathrooms and set to come on with the bathroom fan. Russ
