The Wireless Vent and Filter Boost Remote provides one-touch control of your ventilation system from bathrooms, laundry rooms, or any location in your home or building. The remote has three buttons: 20, 40, and 60 minutes. The ventilator can be temporarily boosted for 20, 40, or 60 minutes, depending on the button pressed. Pressing one of these buttons temporarily boosts the ventilator for either the time on the button or the current run time at the thermostat, whichever is greater. Vent boost can be cancelled from the thermostat.
